Introduction
Lap Timing
Displaying your Lap times as you drive around a circuit is simple with PerformanceBox. You can
display your last and best Lap times and Lap count, and also display split times for up to six
specified split points around the lap. The split files can be saved and reused should you attend the
same circuit again, guaranteeing consistent data. You will be able to catalogue and review your
performance over any given period of time.
Through the PerformanceBox website and forum you are able to download circuit overlays from
around the world, compare lap times, and share lap overlay data with other users.
Speed Display
PerformanceBox has a display screen mode that shows a large digital speed value and compass.
In open conditions, PerformanceBox has a velocity accuracy of 0.1km/h, which is useful for
checking the accuracy of your vehicle’s speedometer.
In this mode there are also Odometer and Height display screens.

Introduction
Power Calculations
PerformanceBox can help you to measure the power developed by your car’s engine, either at the
wheels or flywheel. Having set the vehicle weight, results are calculated from the measurements
taken by the fast GPS engine to give you useful guidelines to the car’s brake horsepower or
kilowatt output. Because these calculations are made from the GPS data rather than
accelerometers, your results are likely to be more consistent and accurate.
Data Logger
For drivers keen to improve their lap times and get valuable feedback on technique,
PerformanceBox includes a sophisticated, fully functioning data logging package. If used with a
64mb SD card, PerformanceBox can log up to 50 hours of continuous data, which can be analysed
in great detail in the available software.
This software allows graphical analysis of acceleration, braking, cornering and lap times, and if the
PerformanceBox is used in conjunction with a Micro Input Module, data from the vehicle itself
(such as RPM and throttle angle) is recorded alongside the GPS parameters.
You can overlay up to four files, and you get an accurate track map to compare your driving line
between different laps. The software also features a graph measure tool, allowing for precise
analysis of performance figures. Data-logging capabilities are further enhanced by automatically
generated text data on the SD card.

Satellite Reception
PerformanceBox calculates all of its logged data from the information it receives from GPS
satellites and relies on being able to get a good lock to produce this data. So it is imperative that
PerformanceBox (or optional external antenna) is placed in the best possible position for a clear
view of the sky.
If you are using an external antenna, ensure that it is connected before you power up
PerformanceBox.
The location that you drive in can also affect data quality, if you drive in a very built up area or an
area with overhanging trees then the signal quality can degrade. If the satellite reception does drop
out in use, you will see either of the following symbols:
1.

Searching for satellites at power up
Whilst the PerformanceBox is acquiring satellites it will flash the image of a satellite, the location of
the flashing image depends on the screen you are in.

results for every performance test made using the PerformanceBox, each time appending the data
onto the end of the file. The second file, ‘BESTXX.TXT’, displays only the best results achieved for
each type of test, overwriting previous results when required. If the unit is power-cycled, two new
files will be created with an incremented file name and all data will be written to the new files
instead.
Results text files are only created on the SD card if the ‘Write Results File’ option has been chosen
from the Performance Mode Menu:

Speed Buzzer
The Speed Buzzer can be used in such tests as 0-100-0, as an audible warning when a certain
speed has been reached. This means that during such testing the driver will not need to watch the
display and can listen for the buzzer instead.
To change the speed at which the buzzer will sound, enter the MENU from any mode, scroll to
Setup and click OK. The speed buzzer is one of the options in the Setup menu. Pressing either the
▲▼ alters the speed setting.

Lap Timing Mode
Laptiming Mode
PerformanceBox can be used to measure lap times by storing the position of a virtual gate and
using this to trigger the start and end of a lap. Further locations can be added to represent split and
dedicated finish lines.



Start/Finish Line: Defines the point at which one lap ends and another starts. It also
defines the start of a test that ends in a different location, such as a sprint or slalom stage.
Split Line: Defines a point on the track or stage at which intermediate time and speed
measurements are displayed.
Finish Line: Used only in point-to-point tests (such as sprint or slalom tests), to mark a
finish point that is in a different location to the start point.
Measuring Lap times
There are two ways of measuring lap times as you drive round a circuit: by setting the start/finish
and split points through the PerformanceBox menu screens, or by using the ‘Simple Lap Timing’
option. The latter is useful if the user is in a situation where several button presses are difficult to
achieve, such as during a qualifying run.
Simple Lap Timing
This method of lap timing requires just one button push to set up a start/finish line. With the
PerformanceBox in Lap Timing mode, press either the up or down arrow key as you drive over the
desired start/finish point. The screen will then display the following message:
The screen will then count down to 0 and revert to the normal lap timing screen:
If an arrow button has been pressed in error this count down allows you to abort the setting of the
start finish line, whereupon the lap times will be calculated according to any previous start/finish
points that may have been set.
As soon as the start / finish line is crossed again, lap timing will begin. The lap time will be

Lap Count
A count of the number of completed Laps is displayed in the top left corner of the Lap timing
screen.
To reset the Lap count and the Best Lap time, press the RESET button.
Lap Timing Including Split Points
This method allows for the setting of a start/finish line, up to six split points, and a separate finish
line if the course being driven is of a sprint or hill-climb type. Due to the fact that it requires several
button pushes it is best employed in a non-race session.



Firstly set the start/finish line and splits or load a previously saved set from the SD card
(see Setting Start/finish and Split Lines below).
If you want to save your lap times to a file, insert an SD card.
Drive around the circuit, your times will automatically appear on the PerformanceBox
display:
Big Speed @ Split display
There is a choice of what is displayed in the main area of the Lap timing screen, either your
Lap/Split time, as shown above, or the Vehicle speed as it crosses a split point or start/finish line;
with the current lap in the upper left and the split time in the upper right of the window:
If Split points are placed at the exit of corners then this mode displays the corner exit speed, which
is a very easy way to help you improve your speed out of a particular corner. To display the exit
speed at the last split instead of the time press the MENU button and change the ‘BIG SPEED @
SPLIT’ option.

Split to Split time
There are two different ways of measuring split times. The default is from the start of the lap to the
split, the other method is from one split to another. To change between these options, tick or untick the option ‘SPLIT TO SPLIT TIME’ in the LAPTIMING MENU.
Split Widths
When setting a start / finish or split line, PerformanceBox will set the width of the line at a default
value of 25m (12.5m either side of the point at which the OK button was pressed.) However this
can be changed by selecting the Split Widths function and altering the value using the ▲▼ buttons.
This feature is useful if PerformanceBox is being used on a track where separate sections pass
closely by each other, and eliminates the possibility of going through a split line in the wrong
direction.
Clearing your Best Lap time
Press and hold the RESET button for 1.5s.
One Shot Mode
By default, PerformanceBox starts the lap time from a start / finish line. If you want to start the lap
time from the moment you start moving, then you need to select ‘One Shot Mode’. To set this
mode:
 Press the MENU button to enter the LAP TIMING menu.
 Highlight ‘ONE SHOT MODE’ and press OK to activate.
 Bring the car to a halt at the start point (previously set using either set start/finish method.)
 After two seconds the following screen will appear:

When this screen shows you can then start your lap. Timing of your lap will start as soon as
you pull away and will then stop as you cross the start / finish line at the end of your flying
lap.
Start / finish and split lines
Before PerformanceBox can measure and display times, you will need to either load previously
recorded start / finish lines or create new ones in your PerformanceBox. This is done using either
Simple Lap Timing, mentioned above, which sets only a start / finish line. In order to set a start /
finish AND split points, follow the instructions below.
Setting start / finish lines
1. Press the MENU button to display the Lap Timing Menu.
2. Highlight ‘SET START & SPLITS’ and press OK
3. As you drive across the start / finish line press OK
4. This will set the start / finish line and the screen will now show the SET SPLIT1 screen.
5. To set the first Split, press OK when you pass this point or press RESET to skip.
6. If you wish just to place a separate Finish line, press the ‘RESET’ button to skip all the split
points and scroll to the SET 2nd FINISH screen.
7. Press OK to set a separate finish line as you drive over it.
Note: you must be moving to be able to set virtual lines.

Saving start / finish and Split Lines
After creating start / finish, Splits or Finish lines you can save them to a file on the SD card which
can be loaded back into PerformanceBox at a later stage, or used in the VBox Tools software. The
file created is called DBOX.DSF and is saved into the ‘DATA’ directory on the SD card. If a
DBOX.DSF already exists the file will not be created; this is to prevent existing start and split lines
being accidentally overwritten.
To Save the lines you have created:
1. Ensure the SD card is inserted.
2. Press the MENU button to enter the Lap timing menu.
3. Highlight the SAVE SPLITS option and press OK
Loading start / finish and split Lines
You can load start and split line information from a file stored on the SD card into your
PerformanceBox. By default the PerformanceBox looks for a file it has saved out; DBOX.DSF in
the ‘DATA’ directory. If no DBOX.DSF file is found the PerformanceBox will look for a ‘DSF’
directory and display a list of all *.DSF files in that directory. This facility allows you to keep a
library of split lines files on the PerformanceBox from multiple test areas or circuits.
To Load a split line file:
1. Press the MENU button to enter the Lap timing menu.
2. Highlight the ‘LOAD SPLITS’ option and press OK
Clearing start / finish and split Lines
This option will erase the split line information from the PerformanceBox memory, not from the SD
card. Split line information remains in the PerformanceBox memory until they are either cleared or
re-entered, even if the unit is power cycled.
1. Press the MENU button to enter the Lap timing menu.
2. Highlight the ‘CLEAR ALL’ option and press OK
Recording and Reviewing Lap and Split Times
To record your run data and lap and split times, simply insert a SD card into PerformanceBox, the
run data will be recorded in a ‘.dbn’ file on the SD card and the Lap Time information will be
recorded in a text file e.g. ‘Laps-01’.txt’

Predictive Mode
Predictive Mode
Predictive mode enables you to graphically view your predicted lap time. Predictive lap timing
works by saving your position around a circuit, every second. If the current lap is the fastest so far,
then this positional data is saved as a reference.
.
This screen is shown when comms mode is set to VBOX Tools. Pressing the OK button changes
the comms mode to Mass Storage which enables predictive mode.
This message on screen means the Drift Box is receiving positional data from less than three
satellites.
If the Performance Box loses satellite lock while predicting, this screen will appear. The user will
have wait until the start finish line is crossed before predicting again.
Before Predictive mode can operate, you will need a reference lap. If a reference lap file is found
on the SD card as the Drift Box boots up, it will be automatically be loaded. A reference lap file can
be loaded from the SD card at any time using the Load Reference menu option. The Drift Box will
display this screen when no reference lap is available. Once a Reference lap has been set, the
Drift Box will start predicting when the start line has been crossed.
If you do not have a reference lap file, you will have to wait until a full lap of the circuit has been
completed. This screen will be displayed while the drift box is creating a reference lap.
02/05/2014

Predictive Mode
Once a valid reference lap has been created or loaded, the Drift Box will begin predicting. The
prediction is shown in text and graph format which is a graphical representation of the amount of
time gained or lost around the lap.
When a lap has been completed this screen is displayed for five seconds before reverting back to
the prediction screen.
Fixed Lap
In predictive mode your reference lap will change if it is faster then the previous. Pressing the OK
button will fix your current lap, preventing it from changing. Pressing OK again on the same lap,
cancels the fixing. Pressing OK on a later lap will cause that one to be fixed.
If you decide to load a lap file from the SD card, it will automatically become the fixed reference lap.
Anything that resets predictive mode will put the unit back in to normal non fixed predictive mode.
This includes pressing the reset button, clearing splits or performing a power cycle.
You are able to set the scale of the bar display with each gradation representing a set number of
seconds. The options available are 0-2s, 0-5s, 0-10s and 0-30s. This can be changed by selecting
MENU and then BAR RANGE.
To save a reference lap, Press MENU and then select SAVE REFERENCE.
If you wish to clear your reference lap to enable you to create a new one, holding down the RESET
button will allow to you to do so. Clearing the split points on Laptiming mode will also reset the
reference lap. Please note, once you create a new reference lap, the previously saved one will be
overwritten.

Power Mode
Power Mode
Your car’s power output can be measured using the Power Mode. There are two parts to this
process: the acceleration run, which gives you the power at the wheels minus the losses caused
by tyre and air resistance. The second part of the test measures these losses and also estimates
gearbox losses. The Power Mode is also an additional tool for car tuning, where access to a
chassis dynamometer is not possible.
Note that this is an estimation of power, and as such when carried out correctly will probably be
within 5% of the true figure. It is very important that the test is carried out on a completely flat road
and the correct procedure is followed very carefully. Power output can only be measured on a car
with a standard manual gearbox.
Power Testing
Please note that due to the nature of this test and the amount of space
required, it is strongly recommended that such measurements are
conducted on private roads.
Setting the Vehicle Weight
In order for accurate measurements to be made, the vehicle weight must first be entered via the
Power Menu:
POWER MENU
UNITS
SET WEIGHT
SETUP
EXIT
The weight you enter must be as accurate as possible - for best results have the car weighed prior
to carrying out any tests as even a small inaccuracy will not give correct power figures, a 10% error
in weight will give a 10% error in power. Use the ▲▼ buttons to increase or decrease the weight
value (Holding down the buttons increments/ decrements faster). Altering the units from the menu
will change the weight values from lbs to kg, and the power values from bhp to kw.
Power and losses runs should be carried out on level ground and always in the same direction,
and it is recommended that power runs are conducted with the car in second gear.
02/05/2014
Page 27
Racelogic Ltd
Power Mode
Power Runs
Once the vehicle weight has been set, a simple power run can be carried out to give engine output
at the wheels. Put the car into second gear at a low RPM, 2000 RPM or less.
Press OK, the next screen indicates that PerformanceBox is ready to record the run:
Once the car begins to accelerate, the power is being recorded:
Accelerate to the top of the engine’s rev range, disengage the clutch and make a note of the car’s
speed as this will be required during the losses run, then coast for a few seconds. PerformanceBox
will record the amount of power as soon as it recognises deceleration:
Calculating Losses
So as to estimate power output figures at the flywheel, you will need to configure the amount of
loss generated by tyre and air resistance. To do this requires a ‘coast-down’ test. It is
recommended that this is carried out in third gear.
With the weight correctly entered, switch from the Power Run screen to the Losses Run screen
using the ▲▼ buttons. The screen will display a similar initial instruction to the Power Run:
02/05/2014
Page 28
Racelogic Ltd
Power Mode
Begin to accelerate, and press OK. Continue to accelerate to the top of the engine rev range.
At the top of the rev range, disengage the clutch and put the gearbox into neutral. Once
deceleration has begun the screen will display the recording information:
Let the vehicle coast down to a speed a long way below the speed at which maximum power is
likely to occur, then accelerate briefly to finish the run:
Press OK to save the losses; pressing RESET will cancel the recorded losses so that you can start
the process again. Losses are permanently saved, but you should generally carry this out on the
same piece of road in the same direction as your acceleration runs. Note any small gradient can
have a large effect on the measurement.
If you have not carried out any power tests at this point then accessing the Power Run screen will
simply display the priming instructions. If you have already carried out power runs the results will
now be displayed as output from the flywheel rather than the wheels. Any further power runs will
display the results at the flywheel, until the RESET button is pressed when in the Losses Run
screen.
Pressing the RESET button when in the Power Run screen will clear the result in order for a new
run to commence.

Input Module Screen
The Input Module screen provides the ability to configure the input and output channels of a
connected Micro Input Module and view the data on each of the input module channels.
NB: This mode requires the RS232 chip upgrade in order to function.
Input module connection
The PBOX connects to a Micro Input Module using an RLCAB045 cable plugged into the Auxiliary
connector on the back of the PBOX to the DATA socket on the Micro Input Module. If an input
module is connected to a PBOX and it has been initialised then the PerformanceBox will
automatically log all of the input module channels to the SD card.
Initialising the Micro Input module.
In order for the PerformanceBox to log the input module data channels, the Input Module screen
must be accessed whilst the input module is connected and the PerformanceBox has satellite lock.
After the Input Module screen has been accessed the screen will briefly display the following
message.
Then the screen will display the data output diagnostic screen. Once this has happened the
PerformanceBox will log the input module data. In firmware revision 1.4.76 and above a new
display can be accessed by pressing down in this mode.
This screen displays Speed and a selected input module channel. To select an input module
channel press the MENU button then navigate through the list to select display channel. From this
screen any one of the MICIN01 channels can be selected.
NOTE: After each power up, the Input Module Screen on the PerformanceBox must be accessed
in order for the PerformanceBox to recognise the presence of the MICIN01. After this has been
done, then any of the PerformanceBox screens can be used, but this must be done or the MICIN01
channels will not be logged.

Data Logging
Data Logging
Providing that you have registered your PerformanceBox (see Quick Start Guide) then it will be
capable of logging data to an SD card.
Using the SD card
The Performance Box will only work with SD and SDHC hardware.
Files logged by PerformanceBox are named ‘PBOX_001.dbn’, where 001 increments when a new
file is created. A new file is created every time PerformanceBox is powered up, or when the card is
re-inserted. If you wish to log data to the SD card then simply insert the card into the slot in the
front of PerformanceBox. PerformanceBox will log vehicle position, speed and acceleration into a
binary ‘.dbn’ file which can be opened in PerformanceTools software for analysis. This data is
logged when velocity is above 0.5Km/h.
The PerformanceBox has two logging modes, selectable through the SETUP menu available from
any screen.

ONLY WHEN MOVING: In this mode GPS and PerformanceBox data is only logged to an
SD card (.DBN file) whilst the Speed is greater than 0.5km/h.
Only ever remove the SD card when you are stationary, otherwise you will risk losing
data or corrupting the card (which would require a re-format).

CONTINUOUS: In this mode all GPS and PerformanceBox data is logged to the SD card
(.DBN file) regardless of Speed or satellite reception.
Before removing the SD card, the data-logging process must be stopped by pressing
the MENU button, which ends the writing of data to the card and closes the current
file.
To read data from the card either insert the card into a SD card reader connected to your computer
or connect your computer directly to PerformanceBox via the supplied USB cable to read the data
from the card. PerformanceBox must not be writing to the card when you connect to your PC, so
you must be stationary. To ensure Windows recognises a PerformanceBox, power up your
PerformanceBox before connecting the USB cable to your PC.
File types
Below is a list of the file suffix’s and definitions that are used by PerformanceBox and
PerformanceTools Software:
Type
*.dbn

Coldstart
Cold Start
A cold start completely re-initialises the PerformanceBox’s GPS engine. GPS coldstarts clear the
GPS engine’s list of satellite positions and configures the GPS engine for normal PerformanceBox
operation. For this reason, coldstarts should be performed at the following times:



If PerformanceBox has not been used for more than three weeks.
If PerformanceBox has moved over very large distances (thousands of miles) whilst turned
off.
If PerformanceBox’s firmware has just been upgraded.
Because each of these are common during distribution, it is also recommended that the
PerformanceBox is coldstarted on its first use. After performing a Cold Start the vehicle to which
PerformanceBox is connected should be left in an open area for at least 15 minutes, to re-acquire
the satellite almanac. You should only need to do a cold start when you first receive your
PerformanceBox, or you are experiencing poor satellite reception in an open area.

Troubleshooting
Troubleshooting
My PerformanceBox does not pick up or lock onto satellites.
Some modern cars are fitted with a special windscreen that cuts down the amount of UV (Ultra
Violet) rays that will be transferred through the windscreen which help cut down on glare. These
windscreens are called athermic, or UV Coated and will dampen/reduce GPS signals coming
through the windscreen, so if you have an athermic windscreen, it means you will not receive the
same quality of signal as you would do by taking the PerformanceBox outside of the car.
How do I know if I have an Athermic Windscreen?
You can either contact the manufacturer of your vehicle, or talk to the main authorised dealer who
may be able to tell you. If you cannot receive a firm yes or no, then another way to check is to
power up the PerformanceBox and hold it outside of the vehicle, receive a satellite fix and use the
GPS diagnostic screen to see how many satellites you can see. Once you have noted this down,
move the GPS inside the car and see if the GPS signal drops by 2-4 sats. If it does immediately
then you probably have an athermic windscreen.
There is list of cars in the table below that we believe have had Athermic windscreens fitted
throughout part of their history. Please note that manufacturers don't always use the same
windscreens through the life of a car model, so even though a model may be listed below, it does
not necessarily mean that the current model that you have may have an Athermic windscreen. If
you are unsure, try the above test or talk to your car manufacturer/dealership.

If your car does have this type of windscreen you will need to use an external GPS antenna that
magnetically fixes to the roof of your car. An external antenna is available as an optional extra see the website for details.
If you still have reception problems:
 Obstructions to the open sky will reduce GPS performance. Try to ensure placement of
PerformanceBox is away from the windscreen edges so it has the widest view of the skies
possible. With an external antenna place it away from roof bars and at least 10 cm way
from any other roof mounted items.
 Driving in built up areas and close to tall trees reduces satellite reception.
 PerformanceBox may require a Coldstart, see the PerformanceBox setup section of this
manual for more information.
No data files are appearing on the SD card
Make sure the SD card is not full. If your PerformanceBox does not beep twice when you insert the
card, then you may have to re-format the card - you should use the utility in PerformanceBox Tools.
If purchasing a new SD card, ensure that it is of high quality from a reputable manufacture

The PerformanceTools software allows you to view the driving data recorded by
PerformanceBox in a ‘.dbn’ file. The software also allows you to display Lap times,
Acceleration, Deceleration results, and to carry out detailed analysis of driver and vehicle
performance.
Installation
Each PerformanceBox is supplied with a CD containing the PerformanceTools software.
Insert the CD into your computer, the installation should then auto run. The Installation will
place a shortcut onto your desktop for the main analysis software, and also install USB
drivers for upgrading your PerformanceBox. The software installation is also available from
the downloads section of the PerformanceBox website, along with the current firmware
release.
PerformanceTools Windows
PerformanceTools is made up of several windows, each displaying a variety of data in both a
graphical and textual form.
When the software is started for the first time after installation, and before any files have
been loaded, the windows visible will be the Toolbar, the Graph screen, the Graph:Data
screen, and the Graph:Map screen:
There are additional windows that can be displayed, according to the functions being
employed to analyse your data – these will be described in subsequent sections of this

Other channels will appear if a Micro Input Module has been used together with the
PerformanceBox, such as RPM or Analogue_1.
There are a number of other channels which are shown, but these are not relevant to the
PerformanceBox and will be blank. For reference, these channels are: Relative Height,
Vertical Speed, Glonass Satellites, GPS Satellites, Lat Acc from Yaw Rate, DGPS, Speed
Quality, Centre Line Deviation, Solution Type, RMS Error Position, and any channel with an
underscore at the start of its name, such as _latitude.
Window Sizes and Positions
Each of the three display windows can be resized by stretching the window (by holding the
mouse pointer over a window corner and then click-dragging when the pointer shape
changes to ); each window can be repositioned; and all of these windows can be printed.

Software Basics
Opening PerformanceBox Files – Load All
To load a file that has been recorded by your PerformanceBox,
click on the Load All button on the Toolbar. An ‘Open’ window will
appear – navigate to the directory on your PC that contains your
PerformanceBox files and select the file you wish to view.
By default the ‘Files of Type:’ will be ‘PerformanceBox Binary Files (*.dbn)’, with a further
option of ‘VBOX Data Files (*.vbo)’. Unless you are loading files that have been recorded
using Racelogic VBOX equipment you will not need to select the .vbo file type.
Data Display
Once a file has been loaded the three windows will each display some information, as
described in PerformanceTools Windows on page 35.
Note how in the example above, the Graph window is showing speed in Km/h (Y axis), and
time in seconds (X axis); the Graph:Map shows the path the vehicle took whilst the file was
being recorded (in this example the Laguna Seca circuit in the United States); and the
Graph:Data window is displaying values from the file according to the position of the cursor in
the Graph window.
The Toolbar displays the file name and total run time next to the PerformanceBox logo.
Graph Set-up
The Graph Set-up button brings up a list of options that apply to all three of the main
windows, and can also be brought up by right-clicking on any of the three main windows.
Each function is described in further detail in the following sections.

Moving Around the Graphs
Once a file is displayed the data from the file can be examined more closely using the
following basic functions: zoom, pan and cursor movement.
Cursor
The position of the cursors in the Graph and Graph:Map windows are linked and move
together, and the values displayed in the Graph:Data window update as the cursor is moved
through the file. The left and right arrow keys control the movement of the cursor. If the shift
key is simultaneously pressed then it moves faster across the screen; if the ALT key is
simultaneously pressed then it moves through the file one sample at a time (one-tenth of a
second.)The cursor can also be placed in the graph window by left-clicking the mouse button
at the desired cursor position.
Zoom
Zooming in on the data in the graph or map window can be done three ways.
 Use the left mouse button to click and drag a window from left to right around the
area of interest. Click and drag from right to left to zoom out.
 Use the up and down arrow keys on the keyboard to zoom in around the current
cursor position. Pressing the shift key at the same time makes the zoom happen in
bigger steps.
 If your mouse has a scroll wheel then this can be used to zoom in around the current
cursor position. Pressing the shift key before using the mouse roller ball will make the
zoom occur in bigger steps.
Pan
To pan the view in the graph or map window, put the mouse over the area you wish to pan
then click and hold the right mouse button and move the mouse in the direction that you

To swap the X axis from Time to Distance either press the right mouse button anywhere on
the screen or click the ‘Graph Set-up’ icon, then select ‘Graph Type’, then choose one of the
two options, ‘Speed Against Time’ or ‘Speed Against Distance’.
Speed against distance is useful for overlaying laps with different lap times around the same
circuit (eg. different time, but same distance)
Speed against time is useful for examining performance files (acceleration and deceleration.)

Graph Screen Y Axis
The default view on the Y axis is for speed, in either MPH or KMH. More axes can be added
to either side of the graph screen – see ‘Axis Setup’.
Additional File Functions
By clicking on the small arrow next to the Load All button, a further set of file-loading options
is revealed:
Load Compare File
The Graph screen has the facility to load up to three more files for
comparison. Select one of the ‘Load Compare File x’ items and choose
an additional file to examine: the data will be overlaid in the Graph
screen, another data set will be displayed in the Graph:Data window,
and the comparison file’s path will be overlaid in the Graph:Map
window.
To remove a compare file, click on the ‘Remove Run’ icon in the
Toolbar and then select the relevant file to remove.
Append File to Main
PerformanceBox files can be joined together using the ‘Append file to
Main’ option. This is a useful feature if you want to join track sessions together in order to
carry out lap time analysis on a whole day’s circuit practice, or to view an entire journey
which was punctuated by stops.
Appending a file will join the beginning of the additional file to the end of the main file.
If you wish to append files to the middle of the main file it will be necessary to
manipulate the main file first using the Edit Data functions (see Editing a
PerformanceBox File.)
Note that if you have loaded a comparison file, this will be removed by appending an
additional file to the Main Run.
Open in Notepad
A PerformanceBox file can be opened in Notepad by selecting the ‘Open In Notepad’ option
from the ‘Load All’ drop down list. Note that for large files, it may take some time for Notepad
to load all of the lines of data.
This function can also be used to open the other text files on your SD card such as the lap
time results files, Results.txt and Best.txt.
Load Circuit Map
This feature allows you to load a circuit overlay file in addition to your logged
PerformanceBox data, and is covered in the section ‘Circuit Overlays’ on page 59.
Editing PerformanceBox Files
Sections of a PerformanceBox file can be removed using basic editing commands accessed
through the ‘Edit Data’ icon in the Graph screen toolbar. Note from the screenshot below that
each editing function has a keyboard shortcut.

Cut All Data before Cursor
This feature removes the entire file up to the cursor
position in the main memory (ie not any compare files
currently loaded) only. You can use this to select an area
of the graph you are interested in and then save just a
portion.
Cut All Data after Cursor
This feature removes the main memory file from the point
of the cursor onwards.
Cut Data between Two Points
This feature removes a section of the main memory file between two specified cursor points.
When choosing this option instructions will appear on the screen:
Saving PerformanceBox Files
Save a file by clicking on the ‘Save’ icon in the main toolbar. If you have made changes or
edited your PerformanceBox file it is wise to save this file to a new name so that you do not
lose the original file.
A .dbn file can saved in three alternative formats:



Circuit overlay file (.cir): a file created to display the bounds of a circuit, for drive-line
analysis.
VBOX data file (.vbo): essentially the same as a .dbn, but in ASCII rather than binary
format.
Comma-delimited spreadsheet file (.csv): a raw data spreadsheet file, with all logged
information in channel columns.
Printing Graph Data
You may print out the graph data currently being displayed by selecting an option from the
‘Print’ icon’s drop-down list. It is possible to print a single window (Graph, Data or Map) by
selecting the relevant options, or all three by selecting the ‘Print’ option (or by clicking the
‘Print’ icon itself, rather than its arrow.)

Exporting Graph Data
It is possible to export the graph or map as a picture file, which can either be saved or copied
onto the computer’s clipboard for use with other software. Simply click the ‘Export’ icon and
then choose the image to export. A dialogue box will appear that will allow you to choose
several factors, including the format in which you wish to export the file:

Selecting Channels
All channels logged by PerformanceBox appear in the data window; all except speed are
initially greyed out, but the data can still be seen. To enable a particular channel and make it
visible in the Graph window, click in the tick box to the left of the channel name. For example,
to display lateral acceleration:
Click here to
turn the channel
on or off
PerformanceTools will automatically scale the channel to its minimum and maximum values
and show it in the graph window. The enabled channel will then be highlighted in its display
colour.
The data table contains all of the logged channels from the PerformanceBox file plus Lateral
and Longitudinal Acceleration and Radius of Turn channels, calculated when the file is first
loaded. Scroll up and down the channel list to find the desired channel.
A channel can also be found by typing the first letter of the channel, for example ‘S’ for
Satellites, providing that the data table is the currently active window. If there is more than
one channel that starts with the same letter then press the key again until the software stops
on your desired channel.
Show Selected Channels Only
The data table channel list can be reduced to show only the ticked channels, by right-clicking
the mouse pointer in any ‘graph’ window (Graph, Data, or Map) then selecting ‘Show
Selected Channels Only’. This is very useful when you are moving the cursor through the
graph window and wish to see the displayed channel’s data at the cursor point:

Channel and Axis Setup
For each channel there are a number of attributes that can be configured, including those
relating to the y-axis. These are configured in the Channel Set-up and Axis Set-up screens,
which are accessed by double-clicking on any of the channels in the data table or by right
clicking the mouse button and selecting the ‘Channel scaling & Axis setup’ option, or by
clicking the ‘Graph Set-up’ icon on the Toolbar.
Channel Setup
Column descriptions:
Visible
The tick boxes in this column switch individual channels on or off in the graph window.
Channel Name
This column contains the names of the available channels.
Units
Shows the units of each of the available channel.
Smoothing
In this column a smoothing level can be applied to each channel individually. This can be
useful for the Longitudinal and Lateral Acceleration channels. The smoothing level number
directly relates to the number of samples used in the smoothing routine – the higher the
value the smoother the trace will appear on the screen, but it will become less representative
of the response of the vehicle as it was actually recorded:
02/05/2014

PerformanceTools Software
The example on the right
shows the Lateral
Acceleration channel
with a smoothing level of
2.
This example shows the
Lateral Acceleration
channel with a
smoothing level of 25 –
note how the individual
peaks and troughs are
no longer present, so
the true dynamic values
of the vehicle are now
not shown. Smoothing
Level should therefore
be carefully applied –
too little and the data
can be too ‘noisy’ for
easy analysis; too much
and valuable information
can be lost.

PerformanceTools Software
Axis
Displays the axis with which the channel is associated. To change the associated axis, click
the mouse in the right hand end of the axis box once the channel has been made visible. A
common application for this is to display both the Longitudinal and Lateral Acceleration
channels, but to have them referring to one axis only:
Run 1
This column shows the selected colour for each active channel. To change the colour click
on the colour box of the channel and select a new colour from the colour selection box that
appears. The colour chosen will also be applied to the axis, should this be selected; for
example, if the Lateral Acceleration channel is used in green, so too will the Lateral
Acceleration axis, if it is used.
If compare files are also loaded then Run2, Run3 etc columns will be present in which the
colours of these compare file channels can be set:
Axis Setup
The Axis Setup window contains all the controls needed for assigning and configuring the yaxis of the Graph screen:

Each tick box in this column switches an individual axis on or off in the graph window.
Axis Title
Shows the title of each available axis. The axis title is edited by clicking on the box and
entering a new name.
Min / Max
The Min and Max boxes allow the scale ranges for each axis to be set.
Autoscale
The autoscale option causes the axis scales to automatically fit the minimum and maximum
values of the loaded channel.
Symmetrical
This option will cause the positive and negative maximum values on the axis to be the same
magnitude. The magnitude of these will be determined by the largest positive or negative
value of the channel.
Position
This option controls whether the channel axis appears at the left or right of the Graph
window.

Analysing Your Data In PerformanceTools
PerformanceBox Tools has three main features which will allow you gather results from data
you have logged. Many of these results are available to view on the PerformanceBox itself,
but the software allows for more detailed analysis.
This section is divided into two subject areas: Lap Time Results, and Performance (ie
Accel/Decel) Results. It also describes additional features which enhance the analysis but
which have uses within each main function, such as the G-Circle.
Lap Timing
Pressing the Lap timing button in the Toolbar causes the software to scan the loaded file and
apply loaded split file information to produce a table of Lap times, with a V Max for each lap
and with the fastest lap highlighted.
This facility also allows individual laps from the loaded file to be loaded and compared in the
main Graph window. In addition a circuit overlay can be loaded into the Graph:Map window
to aid with drive-line analysis.
02/05/2014
Page 48
Racelogic Ltd
PerformanceTools Software
Start / Finish Lines and Splits
Before you can carry out any lap time analysis you must set a start / finish line in the file you have
loaded. The information pertaining to these points can be saved to start / finish files for later use with
new data from the same circuit, or for sharing with other PerformanceBox users.
Defining start / finish lines and splits in the PerformanceBox software
To define a start / finish line, move the cursor in the Graph window to the desired point, then
press the SPACEBAR to mark a start / finish point, or press the Set Start / Finish button in
the Toolbar.
When the cursor is moved in the
Graph window the cursor in the
Map window follows this movement
so you can see where the cursor
point relates to on the track. After
setting a start / finish line a green
dot will then appear in the Map
window at the corresponding
cursor position.
In addition to the start / finish, up to
20 split points can also be set in
the software. However if you save
the start / finish and splits to a file
for use in a PerformanceBox only
the first six will be saved and used
by the PerformanceBox. To ensure
that only the maximum amount of
splits that can be accepted by the
PerformanceBox are created, an
option to set this maximum is in the
‘Start, Finish & Splits’ menu.
To define the split points, press the ‘S’ key at the desired cursor location or select the ‘Set
Split’ option from the ‘Start / Finish & Splits’ drop down menu.
A separate finish line can be placed when the start line is not
also the finish line. This is used in situations such as hill climbs,
or for data analysis along a stretch of track that does not end
where it starts - such as “Bridge to Gantry” at the Nordschleife
in Germany.
Create a finish line by holding the SHIFT + SPACEBAR at the
desired cursor location or by selecting the ‘Set finish’ button
from the ‘start / finish & splits’ menu.
Note: It is important to try to place the start / finish line at a fast
part of the circuit to reduce the effects of positional error and to get the best lap timing
accuracy.

Page 49
Racelogic Ltd
PerformanceTools Software
Loading and Saving start / finish line and split data
Click on the ‘Save’ option from the start/finish drop down menu to save to the start / finish
and split line information created in the Graph screen to a ‘.dsf’ file. If you want to save more
than six splits for software use only then choose the file type ‘.spl’ instead which is only
compatible with the software and not PerformanceBox itself.
Click on the ‘Load‘ button in the Start/finish drop down menu to load in a ‘.dsf’ or ‘.spl’ file.
The .dsf file must be copied into the DATA directory of the PerformanceBox SD card.
If you have multiple .dsf files from various tracks, it is advisable to keep them stored on the
PC in directories named after the track – then the DBOX.dsf file can be loaded into
PerformanceBox prior to going to the circuit.
Clearing start / finish line and split data
If the current start / finish and split file information needs to be cleared from the
PerformanceTools background memory and display screens, select ‘Clear All’ from the ‘Start
/ Finish & Splits’ menu in the Graph screen toolbar, or from the main ‘Tools’ menu.
Moving Splits
Splits can be moved by pressing ‘M’ in the Graph window and entering the number of the
split to be moved, or by selecting ‘Move split’ from the menu.
Show Split Info on Graph Chart
The start / finish and split lines can be hidden from view by
selecting the Show Split Info on Graph Chart option. This is
available either by right-clicking on any of the three main windows to bring up the context
menu, or from the Graph Setup button on the Toolbar. If you choose to hide the start / finish
and split lines they will still remain active – the software will still generate lap time data even
if the lines are not visible.
Gate Width
The width of the split gate can be set from the ‘Start, Finish &
Splits’ menu.
If you intend to create a .dsf file in PerformanceBox Tools for use
at a circuit, where split points are placed on areas of track which
pass very close to each other, it may be necessary to reduce the
gate width accordingly: this will ensure that you do not
inadvertently drive back through a split point even though you
are on a different section of the track. See the example on the
next page.
02/05/2014
Page 50
Racelogic Ltd
PerformanceTools Software
The circled area circled in green shows two
sections of track passing by each other by only
approximately 20m. If a split point is set on this
section, and the virtual gate has been set too
wide, the split point could be registered by the
PerformanceBox as it passes by in the opposite
direction.
Track proximity can be checked in Google
EarthTM using the measurement tool if you are in
doubt as to how wide the split points should be
created.
Split Names
Split points can be named from the option in the
‘Start, Finish & Splits’ menu. When the Lap Timing – Split Line option is chosen to display lap
times (assuming that split points have been created) an extra column will display the split
names.
Displaying Lap Times
Load the PerformanceBox .dbn file into the software, then define a start / finish
line (along with split points and a separate finish line if required) in the manner
described above, or by loading a .dsf or .spl file.
Press the Lap Timing button on the
Toolbar. The software scans the currently
loaded file, extracts lap times and Vmax
for each logged lap, and displays the data
in a results window.
Note: The fastest lap in the results table
will be highlighted for quick and easy
recognition (see example left.)
Including Split times
If you have set up split points in addition to the start / finish and wish to see the split times
displayed, click on the right hand arrow on the Lap timing button, then from the drop down
menu select ‘Lap Timing – Split Line’. The results table will show the split times as well as
the Lap times in the file.
02/05/2014
Page 51
Racelogic Ltd
PerformanceTools Software
Naming the split files (see ‘Split Names’ above) from the option in the ‘Start, Finish & Splits’
menu will result in the split names being displayed when the ‘Lap Timing – Split Line’ option
is chosen – see the example on the next page, which shows the split points that have been
set on corners at Silverstone Circuit and named accordingly.
Exporting Lap Time Results
The generated results can be exported into other software as a variety of document types by
clicking the Export Results button on the Toolbar and selecting the required file type.
Clearing Lap Time Results
To clear all the results in the results window, click the ‘Clear Results’ button on the Toolbar.
Lap Highlight
With lap data being displayed in the ‘Report Generator – Circuit Test’ window, individual laps
are highlighted in the main Graph screen by clicking on any of the values at the bottom of
individual lap/split data tables:

Loading and comparing individual laps from the same file
Individual laps from the loaded file can be compared to each other in the main Graph and
Graph:Map windows. Each lap shown in the Lap timing table has a Graph Icon
associated with it in the right hand column. Clicking one of these buttons allows that lap to be
individually graphed:
You will now have one individual lap displayed in the Graph window, and one corresponding
column in the Graph:Data window. From the results window, select a compare lap by clicking
a different Graph Icon, in this example the next fastest lap:
02/05/2014
Page 53
Racelogic Ltd
PerformanceTools Software
Result in the Graph window:
The main run is in red, the compare run in blue. In this instance the two laps have been
performed very consistently: the peaks and troughs, which indicate the braking and
acceleration points, sit on top of each other almost every time.
Note that the Graph window’s X axis is set to distance – this makes direct comparison of
braking and acceleration points possible as the distance covered on each lap will be virtually
identical. If comparison laps are loaded when the Graph window’s X axis is set to time, the
data is very much more difficult to analyse.
Result in the Graph:Map window:
Note how in this instance, the driver’s lines have
barely deviated between the two laps – the main
run in red is only just visible below the compare run
in blue.
Three compare laps can be loaded in total,
allowing for comparison of four laps at once (the
main run plus compare runs 1, 2, and 3.) Each
compare lap will have corresponding data
displayed in an individual column in the
Graph:Data window. To change the colours of
each run, open the Channel Setup window and
pick the colours required from the Run x columns.
02/05/2014

Racelogic Ltd
PerformanceTools Software
Loading and comparing individual laps from different files
Lap data created by individual users, and therefore not logged in one .dbn file, can also be
loaded and compared:




Load the first file containing the lap data, set the start / finish line, and click the lap
timing button. The laps will appear in the results window.
Load the next file to be analysed – ensure that the results from the first file have not
been cleared, and do not load the second file as a compare file.
Click the laptiming button again and the second set of lap times will appear in the
results window.
The individual laps can now be chosen as Main and Compare files in the same
manner as before:
In this example, the main run chosen is lap 8 from the first set of times (the same fastest lap
from the previous example.) The Compare Run 1 is lap 8 from another file, which is again the
fastest lap. See below to view the differences in performance as shown in the Graph window.
02/05/2014
Page 55
Racelogic Ltd
PerformanceTools Software
Result in the Graph window:
The main run (1:30.70 – the fastest lap from the previous example) is in red, the compare run
(1:26.10) in blue. Note in this instance how there are differences in the peaks and troughs of
the speed plots, indicating that the faster driver carried more speed before braking, and
accelerated harder.

Replaying Laps (DriftBox Tools Only)
If you have recorded laps loaded into the software you can replay them, by clicking on the
Replay button. By default the cursor will move through the Graph window and round the path
in the Graph:Map window at the same speed at which the file was recorded. However by
clicking on the arrow to the right of the button a faster replay speed can be chosen.
When the Replay button is pressed the Drift Meter and Sector windows will also appear, but
these can be closed if not required.
Whilst the file is being replayed the cursor in the Graph:Map will move around the path taken.
If more than one lap is currently being viewed there will be a cursor for each run, and these
will move around the circuit in a manner according to how the graph window x axis has been
set: if the Graph window is displaying speed over distance, the cursors will move around the
circuit together, as the distance covered during each lap will be virtually identical. However, if
the Graph window is set to speed over time then the cursors will travel according to the
actual lap times.
Note in this example (below) how the green triangle is behind the red and blue triangles –
this is a snapshot of three individual laps being replayed when the Graph screen has been
set to speed over time. This feature allows for ‘live’ analysis of where a driver is gaining or
losing time, and on which part of the circuit.

Set Position Cursor Type
The cursors themselves are configurable: right click on any of the main windows (Graph,
Data or Map) to bring up the context menu (or click on the Graph Setup button on the
Toolbar.) Select ‘Set Position Cursor Type’ and choose the style and colour required for each
cursor. Each run can now display a different shape and colour of position cursor.

Circuit Overlays
A circuit overlay is a file created to map the outer and inner bounds of a circuit, and is a
useful aid in drive-line analysis - comparison of lines taken by different drivers can help to
improve lap times.
NOTE: A circuit overlay is only a feature that can be used in software post-processing – it is
not vital that it is created or obtained prior to visiting a circuit unless specific drive line
analysis, that requires the track boundaries, is going to be carried out between lap sessions.
Creating a Circuit Overlay
There are two ways that an overlay file can be created: either by driving around the circuit, or
by creating a .kml file in Google Earth and importing it into PerformanceBox Tools.
Creating an Overlay File by Driving the Circuit
Note: It is best to use an external antenna to get maximum positional accuracy








Power up PerformanceBox and let it acquire satellites for at least 5 minutes.
Drive to the left hand side of the start of the circuit.
Place the antenna on the left hand side of the roof.
Insert the SD card, ready for logging.
Drive round the left hand side of the circuit.
Stop back at the place you started.
Move the antenna from the left hand side of the roof to the right hand side slowly,
being careful not to cover the aerial – let it see the sky at all times.
Drive at right angles across the track to the opposite side.
Drive round the right hand side of the circuit.
Load the logged file from the SD card using ‘File’ -> ‘Load All’
Save using ‘Save’, select ‘Save as type’ and pick ‘Circuit file’ (‘.cir’).
Creating an Overlay File in Google EarthTM
Please refer to the Google Earth help files for instructions on creating
paths in the software. Once you have plotted a path along the inside
and outside of your chosen track, it must be saved as a .kml file. This
can then be imported into PerformanceBox Tools by clicking on
TOOLS>Import Data
Once the .kml file has been imported, it can be re-saved as a .cir file for
later use with lap data from the circuit. See page 69 for more
information about importing .kml files.
Loading a Circuit Overlay File
The .cir file can be now be loaded into the Graph screen and viewed in
the Map window. To do this, first load a file logged from the circuit in question, and then click
on the drop-down arrow next to the Load All button. Select Load Circuit Map, and choose the
.cir file you have created:
02/05/2014
Page 59
Racelogic Ltd
PerformanceTools Software
If you want to load a .cir file into PerformanceBox Tools on its own, click Load All and then
type *.* in the File name field:
You can then select the .cir file and it will load like a normal .dbn file.
A library of circuit overlay files is available from the PerformanceBox website. If you would
like to share circuit files you have created please contact us and they will be added to those
already available.
Aligning Circuit Overlays and Laps
The standard positional accuracy of PerformanceBox is 5m 95% CEP for Longitude and
Latitude. CEP = circle error probable.
95% CEP means 95% of the time the position readings will be within a 5m diameter circle of
the true position. This error is due to the changing state of the ionosphere, constantly
changing the time taken for the satellite signals to reach the earth. This means that overlaid
laps may appear to miss the edges of the track, especially if the laps or overlay were logged
several hours apart.
The Align Circuit Tracks feature allows post-processing analysis to counter some of this
positional error, by rearranging the driving lines or circuit overlay in the Graph:Map window.
This can be especially useful if the circuit overlay file has been created in Google Earth,
which is not always 100% positionally accurate (a good example of this, at the time of going
to press, is the Paul Ricard circuit in the south of France – the Google Earth image is
approximately 200m adrift of its true position.) It can also help to combat the effects of
positional shift that have occurred between sessions at a circuit, such as morning/afternoon
or one day to another.

Performance Results
Acceleration and deceleration results can be easily extracted from your logged data by using
the various performance results tools. These are available by clicking on the ‘Accel results’
and ‘Decel results’ buttons on the Toolbar.
You can extract speed or distance data for acceleration and deceleration runs. Most of the
tests use standard parameters (such as 0-60 or 0-100) but custom results can also be
produced.
Producing Acceleration Results
Acceleration data can be produced and shown in a results table from the
currently loaded data file by selecting one of the acceleration test options within
the ‘Accel results’ drop down menu. Click on the ‘Accel results’ button to open a
list of the following options:


starting each time the velocity data goes from zero up to a speed of 100 km/h
reached during that acceleration period.
0-160 kmh (0-100 mph): This will tabulate speed, time and distance data
each time the velocity data goes from zero up to a speed of 160 km/h reached
during that acceleration period.
0-160-0 kmh (0-100-0 mph): This will tabulate speed, time and distance data,
starting each time the velocity data goes from zero up to a speed of 160 km/h
then returning to 0 km/h reached during that acceleration - deceleration period.
100-200 kmh (60-130 mph): This will tabulate speed, time and distance data,
starting each time the velocity data goes from 100 kmh up to a speed of 200
km/h reached during that acceleration period.
440 m: This will tabulate speed, time and distance data, starting from zero to
a total distance of 440 m.
18.7 m: This will tabulate speed, time and distance data, starting from zero to
a total distance of 18.7 m.
100 m: This will tabulate speed, time and distance data, starting from zero to
a total distance of 100 m.
Custom: This will tabulate speed, time and distance data, starting over a
custom defined speed range e.g. 0-100-0 kmh.
For each of the test ranges the results table will show Speed, Time, and Distance in
10Kph or 10Mph steps.

the ‘Decel results’ drop down menu. Click on the ‘Decel results’ button to open a
list of the following options:



70-0 kmh: This will output the time and distance taken to decelerate from an
initial speed of 70 kmh to 0 kmh.
50-0 kmh: This will output the time and distance taken to decelerate from an
initial speed of 50 kmh to 0 kmh.
Custom: This will output the time and distance taken to decelerate from one
user definable initial speed to another, e.g. 100 kmh – 0 kmh.
In all of the Decel tests if more than one run is performed an average distance is also
calculated and shown.
Any of the Runs on the table can be omitted from the average by deselecting the tick in the
use box.

Additional Data Analysis Features
The software has additional features to aid in data analysis, explained in this section. Many
of these features can be used as a part of the analysis whilst producing Performance results.
The G-Circle
Pressing the G-Circle button produces a plot of the Longitudinal vs Latitudinal
Acceleration data.
A G-circle (or G-G Plot as it is sometimes known) gives a complete overview of how the tyres
are being used. There is a limit to how much G a tyre can generate whilst cornering, and a
set amount it can generate whilst braking/accelerating. There is often a small difference
between these two values, so you may be able to pull more G in braking than in cornering or
vice versa.
However, if you try and combine
corning whilst braking, then these
limits are reduced. The idea behind a
G-circle is that it tells you how these
can be combined. To the right is a
theoretical perfect G-circle for a
sample tyre.
You can see that the maximum
cornering force is 1g, and max
braking is 0.8g. However, if you are
already braking at 0.6g, then your
max cornering force is only 0.7g.
Plotting out your own G-circle lets you know if
you are exploiting your tyres’ true potential.
Ideally you should get a symmetrical plot, but
bear in mind that you can almost always
generate more G under braking than
acceleration, so the accelerating area will be
shallower than the braking part of the circle.
The example on the left shows a very good
spread of data indicating that the rider
(motorcycle) was able to accelerate and
decelerate whilst cornering to a very good
level, creating a symmetrical plot.
The G-Circle can be examined more closely by zooming in as you do with the Graph:Map,
and by right-click-dragging the current field of view can be moved.

Graph Measure Tool
This tool can be used to highlight a section of data in the Graph window and produce a table
that summarises the data captured in the window:
Measure
Window
Summary
box
Hold shift down whilst clicking and dragging to use the Measure Tool
The area of data that is displayed in the table is highlighted in blue in the Graph window. This
is often useful for quickly establishing average values between two points in a file. In the
screen shot example above the first gear section of the acceleration curve has been
highlighted and it can it can be seen from the table that an average Longitudinal Acceleration
during first gear is easily seen.
Creating a Measure Tool Window
To highlight a section in the graph window, move the cursor to the start of the section you
wish to highlight. Then place the mouse pointer over the cursor position and press and hold
the ‘Shift’ key, then click and hold the left mouse button. Keep the left mouse button pressed
and move the mouse cursor right to drag out a blue highlighted area. At the end of the area
you wish to highlight, release the left mouse button. On release of the left mouse button a
table of results for all channels in the highlighted area appears as in the screenshot above.
Saving and Printing the Measure Tool Data Table
Click the ‘Save to file’ icon in the Measure Tool toolbar to save the data in the table in one of
two formats, .csv or ‘.txt’. Click the ‘Print’ icon in the Measure Tool toolbar to print the table.

Event Marking
Event Marking allows for the Brake Trigger channel to display a change in state – an ‘event’
in a logged file which can be useful for measuring distances etc.
The Brake Trigger channel defaults to a value of 0, until the an event is marked at which
point the value will become 1. The Brake Trigger channel should be set up in the software so
that this can be easily observed, by assigning its axis in a manner such as this:
Note how in the example above, the axis has been set from –0.5 to 1.2 – this allows for the
change in values from 0 to 1 to be very obvious on the graph. If you do not want the constant
value of 0 to be displayed, set the lower axis level to 0 – the event mark will then be
displayed as a ‘spike’ in the graph.
The example above demonstrates an event created by the user holding the OK button on the
PerformanceBox for five seconds: the event will continue to be recorded for as long as the
button is pressed.

PerformanceTools Software
Tools
Clicking on the ‘Tools’ icon on the Toolbar will reveal a drop-down list containing a number of
useful features, such as File Repair and the Exporting Data to Mapping Software facility.
Arrange Windows
The use of different screen resolutions or multiple screens can
cause PerformanceBox Tools windows to be placed out side of the
default screen size, which is then not viewable when the default
screen is used.
This facility allows any PerformanceBox Tools windows that have
been lost off the visible screen to be located back into the visible
screen area.
Export Data
This option allows the location data stored on a ‘.dbn’ file to be
converted into a ‘.txt’ file that may be used with Google Earth,
Microsoft AutoRoute and Microsoft Streets & Trips, to show the vehicle’s path in the mapping
software. This option is also used to create a file that can be used in Track Vision software.
Exporting Data to Google EarthTM
Data can be exported to Google Earth by selecting the Tools menu and choosing the Google
Earth option. The resultant file .kml is recognised by the Google Earth software and allows
data to be viewed on the satellite images.
Upon exporting the file, you will be prompted for an X and Y offset: this allows for data to be
correctly aligned on the satellite images – much of Google Earth is not exactly accurate so
some exported files, such as circuit overlays, may ‘miss’ the edges of the track. The offset
allows for this error to be corrected.
NOTE: if your data file has more than 65,000 sample points the PerformanceBox software
will automatically sub-sample the file to ensure the entire length of the file is represented in
the exported file. Google Earth cannot display files of greater than 65,000 samples.
Exporting to Mapping Software (AutoRoute or Streets & Trips)
Load the ‘.dbn’ file into PerformanceBox Tools using the ‘Load All’ button from the main toolbar, then
click on the ‘Export Data To Mapping Software’ option in the ‘Tools’ menu.
A small selection box will appear, in which the export rate can be chosen.

Importing the Mapping file into AutoRoute or Streets & Trips
Open AutoRoute or Street & Trips. Click on ‘Data’ and then select ‘Import Data Wizard’.
When prompted, browse for the ‘.txt’ file you have just created with PerformanceBox Tools
and open it, then select ‘Comma’ as the delimiter and click ‘Next’. In column F2 select
Latitude as the column name from the drop down menu. In column F3 select Longitude as
the column name from the drop down menu and then click ‘Finish’. The program then
generates a map of your data location and places markers on the map at every data point
that was specified when the output file was, for example once every second.
Exporting To Track Vision
This option creates a csv file with the data in a format that Track Vision software can use.
Formatting MMC/SD Cards
Any new MMC/SD cards are formatted in the correct format suitable for PerformanceBox and
there is no need to format the card. You can delete any files created on the card by
PerformanceBox through your computer when connected to PerformanceBox or when the
card is inserted in a card reader connected to your computer.
However if your card has a problem and the card needs to be formatted it is best to do this
through the PerformanceBox Tools software SD card formatting facility.
Note: that the card will need to be inserted into a suitable card reader in order to format it; it
cannot be formatted through the PerformanceBox and USB cable.
Import Data
Data created in Google EarthTM as a .kml file can be imported into PerformanceTools. This is
particularly useful for creating circuit overlays without having to physically drive the track (see
‘Creating a Circuit Overlay’ on page 67.) Only .kml files can be imported, so when saving
paths created in Google Earth it is necessary to ensure the correct file type is chosen (the
other option is .kmz, and is not a valid import file type for PerformanceBox Tools.)
File Repair
If the file being loaded into the software contains
dropped sample data (caused by travelling under a
bridge, for example) then Performance Tools will
prompt you to repair the file. This can be done by
clicking on the Tools menu and choosing File Repair.
Areas of dropped samples will be then repaired.
Once the repair has been carried out is advisable to save the file and reload it. This will
ensure that all channels are correctly aligned in the Graph screen. Areas that have been
repaired will be represented in the Number of Satellites channel as 0.
A repaired file may still display the Dropouts message upon being reloaded. This is generally
due to the dropouts occurring at a time when the number of available satellites is so low that
an effective repair cannot be carried out (such as travelling through a tunnel.)

Radius of Turn set-up
Click this option to open the Radius of Turn setup
window, in which the smoothing level and maximum
radius value can be set.
When smoothing is applied to data, the value of an
individual sample point is affected by samples around it.
As the effective Radius of a straight line is infinite, the
very high samples of data before and after a corner can
adversely affect the values of Radius in a corner. To reduce this effect it is advised to set a
maximum radius value to a fraction higher than the maximum radius of the corners you are
examining.
Other Features
Some useful features that apply to the whole of the PerformanceTools software have been
included above the main toolbar. These are described in the following section.
Export Results
All Performance or Lap Time results can be exported by clicking on the Export
Results button on the Toolbar. Results can be exported in a variety of formats
such as Excel or Word document files.
Summary
You can view basic but important information about the main ‘.dbn’ file loaded into the
PerformanceTools software by selecting Summary from the menu. The information displayed
includes information such as the time at which the file was logged and its duration, as well as
any errors, such as loss of satellites during the file.
This summary may be printed or e-mailed using the icons at the top of the window.
Units of Measurement
The ‘Units of Measurement’ menu allows
you to set the velocity units to km/h or
mph and the distance units to metres or
feet. Once the units of measurement
have been changed the file must be
reloaded for the changes to take effect.
Help
This menu allows you to view basic information about the PerformanceTools software. It also
provides a quick link to the user manual.
