MECHANIC’S JOB RESPONSIBILITIES OVER RACE/TEST
PRE-EVENT PLANNING

Departure and travel plans should be finalised, with all others involved knowing purpose of test/race.

Mechanic who is charge of running the car should find out:

Noise limits, and take the necessary silencers to pass noise tests.
Session times and where and when signing on is to direct the driver when necessary.

All spares should be checked and packed, with the person who is in charge of the car taking responsibility for test
parts and any extras that may be required.

Mechanic running the car should have all of the cars history and specific car parts, such as fuel dump tanks, dive
planes and have tyres sorted for test/race.

As and when possible have structured test plans for track time available.
MECHANIC’S RESPONSIBILITIES AT CIRCUIT

Follow timetable as closely as possible.

Make sure car is noise tested as soon as possible.

Ensure car is warmed up and ready to go 10 minutes prior to session (Oil at 50°C min and water at 70°C min).

Ensure driver(s) is where they should be - signed on, briefings attended and ready in good time for the session.

Ensure driver is fully aware of any new parts on the car, whether it is brake pads, discs, tyres or development
parts.

Ensure driver knows the procedure for running any new parts, whether or not they needed bedding in, and if so
how it should be done and for what length of time.

Ensure driver knows what is expected of them, whether it’s testing of new parts, bedding-in new parts or setting
the car up.

Ensure a full log of car history is kept, including fuel used, parts used and replaced, running time of car and
development parts, and reasons for changing parts.

Make sure any failed parts are kept for inspection, with technical staff notified where possible.

With parts failures and development parts, and any other issues, be sure to follow correct channels and report to
correct people as soon as possible – i.e. technical team notified.

Make sure the car is downloaded, and check all critical values are within parameters, including:

Oil temp between 70°C and 120°C
Car is charging at 13V to 14V



Water temp between 60°C and 95°C
Fuel pressure around 3 bar etc
Make sure this information is available when necessary.

Ensure all number 2 mechanics have a structured job list to work to, and involve them as much as possible on
decisions to make changes to the car so that they have a better understanding of how the car works.

Appear professional at all times, such as keeping work areas tidy as possible, directing drivers to where their kit
should be stored (i.e. not in working areas)

Once own car is prepped for next session, and all aspects of car are working, i.e. data logger, radio systems etc.,
help out others within the team to get cars ready and out on time.

Try to communicate with others around you so as many people as possible are aware of a situation.

Any extra jobs, other than standard prep, required when the car returns to the factory should be noted, so that
whoever preps the car will be aware of the required work.

Above all, carry out procedures with the Radical Team in mind, acting as a single team and representing the team
in as professional a manner as possible, whether conducting private tests or away assisting overseas clients and/or
distributor.

SERVICE SCHEDULE
As the performance of our cars increases and the number of hours racing the cars grows, we are able to more accurately
predict the lifespan of a car’s components. Please see over, the revised ‘Radical Lifing Information Chart’.
The chart gives the recommended life expectancy of components under ‘normal, on-track racing conditions’. If some of
your racing time is done ‘off-track’ or you hit kerbs, pot holes or other cars – hard, then you will need to consider
reducing the timescales recommended. On the other hand, more ‘gentle’ trackday use will obviously extend the
recommended time!
The recommended life expectancies in no way represent a parts warranty, due to the unpredictable and uncontrolled use
of these racing car components Radical will not be held responsible or accountable for any parts failure. This information
is provided solely as a guide to increase the safety of the cars.

SET-UP PROCEDURE – NEW CAR
1. Check front pushrod lengths are equal & front springs have 3 turns of pre-load
2. Check rear spring platform-to-cap distance is equal (approx. 125mm)
3. Ballast with 80Kg (10Kg in footwell by the pedals, 70Kg in seat) unless specific driver weight called
for on build sheet
4. Lock steering to straight ahead using dummy steering wheel
5. Set tyre pressure to hot pressure from setup sheet
6. Disconnect front & rear anti-roll bars
7. Check dampers are set to minimum all round
8. Bounce & roll car
9. Check drop heights and adjust average of front & rear to be within 1mm of target
10. Set cambers (+ or – 0.1° from target)
11. Set toes (+ or – 0.5mm from target)
12. Roll car off platform, turn on scales and zero
13. Roll car back onto platform, repeat bounce & roll
14. Check corner weights. Target is within 10Kg across front, and within 2% for diagonals
15. Adjust using rear platforms only
16. Re-adjust drop heights equally on front pushrods and rear spring platforms to achieve target. (The
drop height will probably not be equal, due to the offset seating position, so target drop height should be
an average of the left & right readings.)
17. Re-connect anti-roll bars making sure there is no pre-load
18. Set dampers
19. Turn off scales
20. Front diffuser height is set at the middle wooden skid first, at the stated height for the car model (or
not below 40mm) than at the side skids to ensure the front is level. Then set a camber gauge on the
side skirts and make the diffuser top level from front-to-rear and then drill and rivet the rear support
bracket.
ALL Setup Sheets can be found in the Appendix
CORNER WEIGHT SETUP
One of the most important factors is to ensure that the front
corner weights are as equal as possible. The cross weight is not
as crucial in comparison. (The offset driving position of the driver
will usually mean that the weight cannot be made exactly equal.)
152kg
F
160kg
223kg
R
229kg
To adjust the front corner weights, raise or lower the diagonal
rear.
The maximum difference in front weights should be no more
than 10kg (22lb
Cross% = 50.20%

DROP HEIGHT SHEET- RXC (ALL MODELS)
RXC drop heights are measured using the same drop height bar as all of the other models. This is constructed from 2 inch by 1 inch box
section with an additional 2inch by 1 inch box section welded below to give clearance.
Note: On the RXC the drop height bar is used the same on the front as the rear. This is different to the other models (SR3, SR8, SR1).
Please see the following pictures to show where the drop heights are measured to.

HANDLING & SETUP GUIDE
For ALL handling issues the first and most important thing to check is TYRES:


Pressure
Condition
Temperature
Pressure for Dunlop tyres, should be in the range of 28psi to 30psi hot, the working temperature is minimum 70°c and
ideally around 90°c. Temperature spreads, across the tyre tread must not exceed 15°c on the front tyres and 10°c on
the rear tyres. Over 110°c and the tyre is beginning to overheat. The condition can be more complicated; if you know
that the tyres have a lot of miles or have had many heat cycles then, before anything else, try another set.
Also look at the tyres for:


Graining or heavy wear
Unusual colouring
Is there a lot of ‘pickup’?
All these are a good indicator of what is causing problems.
The next priority is to talk with the driver and make a circuit map, if possible, with information on each part of every
corner. You can then decide if the problem is slow, medium or fast corners or everywhere, and if it is entry, mid corner,
or exit. There are always various options to rectify any handling issue and all will have a downside, but we have to try
and chose the best for each corner bearing in mind which the most important corners are, and which problems are
caused by the nature of the circuit.
It is important to understand the difference between understeer and oversteer.

Understeer is when the front tyres have insufficient grip to make the car turn so more steering lock is applied.

Oversteer is the rear tyres not having enough grip.
If you have entry and mid-corner understeer, you will probably get exit oversteer, as you will have applied too much
lock and then when the ‘G-force’ and speed have dropped and you start to apply power it will make the car snap to
oversteer, and this is what the driver remembers so if you try to cure the oversteer it will probably get worse.
This is why it is very important to ask the driver a lot of questions before deciding what to do.
SOME EXAMPLES OF DRIVER FEEDBACK
Driver Feedback
Cause
“Slow speed entry understeer”
The most common cause is too soft front Nik Link or
springs, or front ride height too high, also it could be too
little front rebound.
If braking from high speed to a slow corner the problem is
probably caused by the car pitching too much, so more rear
toe in or lowering the rear ride height will help.
Increasing the rear rebound, if it is entering from medium or
low-speed then softer rear ‘Nik-link’ or maybe springs.
Reducing rear camber will increase rear grip at slow-speed,
so check the rear tyre temps.
“Slow speed entry oversteer”
SIMMS’ MEDAL
NORDSCHLEIFE

LAP RECORD HOLDER
Page 21
QD77-2

With all medium to high speed entry and mid-corner problems, you should first try to solve with an increase or
decrease in front or rear downforce. This can be achieved with dive planes and rear wing flap or with ride-height
adjustment. In general, a lower ride height gives more downforce, and will also increase mechanical grip.

If downforce or ride height is not the answer, then try an increase in camber to increase high-speed grip, but this
in-turn will decrease slow-speed grip.
For example: If you have high-speed mid-corner oversteer, then increasing the camber should help, but it will
decrease traction out of slow corners.

Corner exit problems at all speeds are generally a result of what has happened in the mid-corner. However, out
of slow-speed corners, traction can be improved by reducing rear camber (as above) or softening the rear ‘Niklink’ or springs. Reducing rear compression damping, can help as well.
If you make the opposite change to the front of the car it will also have a similar effect.
In fast corners going stiffer with springs and maybe bars will generally increase grip.

Increasing ‘toe-out’ at front and ‘toe-in’ at the rear will increase stability and tyre temps. Increasing spring rates
and tyre pressure will also increase tyre temperatures and tyre wear.

Damping has many functions, but primarily it is used to keep the tyre in contact with the track by controlling the
spring and chassis movement frequencies, so in general you want to keep the springs and dampers as soft as
possible, but stiff enough to control the roll and pitch of the car. Then, the balance is controlled by the roll and
spring rate differences front to rear and aero levels.

The adjustments on the dampers are called low or high speed compression and rebound. Low or high speed refers
to damper piston speed, not car speed.
For example; on entry to a high-speed corner, the lateral load transfer is relatively slow as you gradually apply more
lock, so the damper movement is slow. Whereas if you go over a kerb at any speed the damper movement is fast,
braking and turn-in to a slow corner is much more aggressive than in a fast corner, therefore the damper movement
is faster, but usually not as fast as over kerbs.
The damping force increases with the speed of the piston:-

If you make the high-speed adjustment too stiff, the damper will not move fast enough and the car will bounce
rather than ride the kerb.

If you have the low-speed adjustment too soft, the car will not respond to driver inputs quick enough in the corners.

Increasing rebound is a good way to increase grip, but it will also increase ride ‘harshness’, which can make the car
skip across the track. There are no simple answers, but damping adjustments are quick to do in the pit lane and will
give you more information to help resolve the issues later.

A
Basic setting:
Front:
A. Rebound
B. High speed bump compression
C. Low speed bump compression
A – Rebound:
The rebound controls the speed of the damper’s extension. The more rebound resistance you add,
the slower the damper will return out. This can be used on the front to fix mid-corner understeer,
and on the rear to aid traction
B – High speed bump compression:
High speed bump compression (refers to the speed of the piston rod into the damper) controls the high frequency
compressions of the damper. In simple terms it controls how the car reacts to small bumps and curbs. We recommend
using no more than +15 clicks from soft.
C – Low speed bump compression:
Low speed bump compression controls how slow or fast the damper reacts under compression. Increasing the low speed
bump will have a similar (though smaller) effect to increasing the spring rate.

Rate Rear
Ideally front ride frequency should be 10% greater than the rear, and the range is 3.5Hz to 5.5Hz for Radicals.
For example; a bumpy track with no fast corners would not require much downforce and would need soft springs so for
an SR3 maybe 4Hz front and 3.6Hz rear.
For a normal track such as Silverstone GP quite high downforce and not too bumpy, you would look at 5Hz front and
4.5Hz rear or stiffer.

WET START POINT
DRY START POINT
To adjust brake bias, press the brake pedal and observe the front and rear pressure shown on the dash. Then move the
adjuster after releasing the pedal to give the required percentage. Then re-check the setting on the dash.
The yellow highlighted values are a good starting point for DRY, while the blue are for WET.
For example - If the dash is showing 35bar front and 26.5 rear, using the chart above this is about 57%. This means you
have too much front brake bias, and you must turn the adjuster to the rear (approx. 1 full turn = 1%), and then recheck
the reading on the dash. Final adjustment will be made by the driver on track to suit their style of driving

BRAKE DISC BEDDING
All cast iron brake discs for competition use need to be bedded-in to ensure heat stabilisation and improve resistance to
cracking. Cracks or warping can occur during the first few heavy stops if careful bedding is not carried out.



If ducts are fitted they should be ¾ blanked off.
Use previously bedded pads.
For a minimum of 15 Km use brakes gently at first from initially low speeds - progressively raise speed to normal
racing speed and gradually increase in pedal pressure.
For the final 2 or 3 applications brakes can be used quite heavily (above 40 bar pressure). The braking potential of the car
will start to fade, this is a sign that the bedding procedure is complete. 1 cooling down lap with moderate brake pressure
is advisable before stopping the car.
It is possible to pick up a vibration or ‘judder’ through the brake pedal. This is due to the disk bell and disk becoming
aligned for the first time; this is not a process that can be simulated in the build of the car. It is therefore very important
that if the driver feels they have brake judder they continue to build up brake pressure and heat in the disk. And not to
stop or decrease pedal pressure, to do so has the potential to make the vibration worse.

After the initial bedding process is complete, allow the brakes to cool. If the car is fitted with a handbrake, do
not apply it at this time.
If AP Racing thermal paints are used then only the green paint (430°C) should have fully turned to white and maybe also
just the Orange paint (560°C) on the outside edges of the discs during the bedding procedure. If fitted, brake pressures
can be used to monitor the bedding in procedure.
PRE-SESSION WARM UP.
With cast iron discs, brake pressures should not exceed 20 bar during the out laps from cold, even with pre-bedded discs.
This includes the start of each track day session, practice session, and warm up of a race.
This is to prevent heat shocking the disc and causing cracking.
Heat shocking occurs when the disc is taken from ambient temperature to 600°C very rapidly i.e. heavy braking on the
out laps.

TYRE SAFETY ADVICE & OTHER INFORMATION

Ensure minimum hot pressures are adhered to! (see tables below)

Calibrate your pressure gauges with DUNLOP personnel.

Do not bleed hot pressures on the car without consultation with DUNLOP personnel.

Fit valve dust caps throughout.

Cold pressures should only be set on tyres that have been shaded from direct sunlight. Do not bleed tyres as the
ambient temperature rises!

Temperature spreads across the tyre tread must not exceed:  15°C on the left front tyre and  10°C on the left
rear tyre. (Temperature measurements to be made at the centre of the tread and 25-30 mm from each edge.)

Please identify your rims, clean them and remove any centre caps before bringing them for fitting.

Avoid hitting kerbs with cold tyres as pressures are still building up.

ADVICE ON THE HANDLING OF RACE TYRES IN COLD TEMPERATURES
Race tyres (car & motorcycle) can be damaged by rough handling in cold temperatures.
The damage occurs in the form of `hairline’ cracks - like very thin splits - often at the edge of the tread and/or the upper
sidewall.
This damage occurs when tyres are handled heavily in low temperatures eg. when `thrown’ to the floor from a truck or
dropped from a storage location.
Based on expert advice from the DUNLOP Development Centre - Hanau (DDC*H), race tyres should always be stored in
accordance with the following recommendations:
Minimum storage temperature +20°C
After prolonged storage in temperatures of less than +10°C, tyres should be handled gently until warmed to +20°C
At 5°C and below it is advisable not to move tyres unless absolutely necessary - and then only with extreme care!

TYRE WEAR PATTERNS
Conversations and judgements about grip and handling should always be preceded with thorough examination of
tyre working surface.
Lots of information and indicators are contained within the whole picture of the tyre and should never be ignored. Not
only grip but also longevity can be estimated, which may be more important. It is the only connection between the tyre
and the road! There must be information for your “Engineer’s Library” in there. Use computer data and visible indicators
to get the best all round view of car and tyre behaviour.
Measure tyre temperatures and pressures as often as possible straight after a fast lap, easily done by getting a driver to
do a full pace “in” lap, in order to get the best readings. However, be sure not to read the temperature of the pickup on
the tyre.
GOLDEN RULES
1.
Watch and ask an expert how to take temperatures properly (Dunlop personnel) and practice as often as
possible
2.
When examining a tyre, always check both sides, as the unloaded side can drag the inner wheel into excessive
negative camber and over heat the inner edge.
3.
Do the loaded side first inner edge to outer edge.
The following is only a guide to make you think more about the subject.
Inside Edge
Inside Edge
Pretty good rear tyre.
If rear grip is good then it’s ok. If rear grip is low, more camber can be added before the tyre is damaged.
Pretty poor front tyre.
Not enough negative camber (A). This car was understeering, looking at the wear depth indicators. The amount of
graining is just about okay for a hard worked tyre.

COLD TEAR
This tyre has only done a qualifying session. It shows signs of something known as “cold tear” (B), which occurs around
the seam of the tread in the centre of the tyre.
Cold Tear is caused by the rubber been torn away rather than grained or rolled. This happens when a driver pushes too
hard, too soon, and with no heat in the tyre. If the driver were to wait one more lap, the tyre would be in much better
condition. The driver may have had a good result in qualifying from this, but the tyre will struggle during race distance.
This is dependent on track type, track temperature, air temperature etc.

RADICAL GEARBOX RUNNING IN INFORMATION
All new gears are lapped at manufacture. However, they are not lapped under the same pressures that driving creates.
The loads generated while driving force any microscopic high spots on the gear teeth back into the surface of the metal.
This is called "work hardening". Work hardening is similar to forging in the way that it compresses the metal molecules
into a very compact and hard formation.
Running in procedure:
1. Keep the vehicle at speeds below 60% for the first 30 minutes of running.
2.
It helps to stop to let the gearbox cool for 15 minutes before continuing.
3.
Build this up throughout the day, with increases of speed and load percentage of 10% every 30 minutes
of running.
 i.e 60% for first 30 minutes, 70% for next 30 minutes, 80% for next 30 etc. This is necessary because
not all of the gear tooth’s are making contact until it is heavily loaded.
When driving, the teeth flex to contact completely, and cause the previously unloaded portion of the teeth to touch and
work harden. It is very easy to damage the ring & pinion by overloading before the teeth are broken-in. If you take it easy
on a new ring & pinion and keep it full of high quality oil, it will last a lot longer.

LIFE DATA SOFTWARE
Life Data is used to download the engine data from the ECU’s internal memory to a PC. The instructions below
explain how to do this.
1.
Connect a computer to the ECU/car and turn both the ignition and master switches on to power up the ECU.
2.
A working directory now needs to be created. This selects the folder in which the data will be stored once it has been
downloaded, and sets a route to find the information. It contains the name of the driver and/or car number etc. For
example C:\Program Files\Life Racing\Track Maps & Data\SR3 (SR5, SR8)\Customer\ Track & Date.
3.
Open the Life Data icon on your desktop.
4.
Select F for file, then W for working directory.
5.
At the top of the screen, below the toolbar will be;
C:\Program Files\Life Racing\Track maps & Data
If not, correct this part by selecting the full stop button… it goes back one section. Then by selecting “create”, a box
comes up with “enter new directory name”. Enter the appropriate information, such as car type, chassis number,
circuit and date. Once this is done, press Enter.
If on the other hand this has been set up the next part will be in the drop down box i.e. Track maps & Data, SR3 or
SR5 or SR8, customer name, track & date. All you then need to do is select the appropriate item until it is complete.
6.
Highlight “select” & press return.
7.
A box comes up with “there is no LR directories config file at: - Create one – select Yes.
8.
Another box with “place shortcut on desktop” select No.
9.
Then select D for device and R for read data.
10. In the next box select ok. If this data needs to be looked at, load up Life View, click on File, Load and then find as
above the appropriate file. Once you have loaded up a data file, the channels will be listed down the right hand side
of the screen, to display a channel highlight it using the arrows on the keyboard and press enter.
If the data needs to be e-mailed go through My computer, Program Files, Life Racing, Track maps & Data,
SR3/SR5/SR8, customer, track & date select file or files to be e-mailed.

LIFE ECU DATA EXPLAINED.
Act1
Air charge temperature.
This is the sensor in the airbox. This should be a constant line without large variations in
reading (spiking). If this sensor has failed it will read 10°c.
Bap
Barometric air pressure.
This sensor is mounted near the engine ECU. It measures atmospheric pressure and
compensates the calibration for altitude and air pressure. This should be a constant line also
without large variations in readings (spiking). If this sensor has failed it will read 1013
Btmax
ECU internal temperature.
Clutch switch.
This is the button mounted onto the steering wheel. (Neutral button)
Ect1
Engine Coolant Temperature.
Minimum temperature before driving should be 50°c. When the car is running on the track, a
minimum temperature of 70°c should be seen. If required, tape should be placed over a
section of the radiator to increase the temperature. If this is required, then the temperature
throughout the day should be monitored to ensure the engine temp is around 85°c.
Maximum driving water temperature should not be over 95°c.
Engineenable
This is used to show when the eop1trip has stopped the engine ( or any other trip)
Eop1
Engine Oil Pressure
The oil pressure trace should follow a similar profile to engine rpm. With the engine on power
and above 9000rpm the oil pressure should not go below 50psi. If the oil pressure drops
against engine revs, Powertec should be contacted and data sent.
If a drop is seen, then it is generally indicating low oil level in the oil tank or oil loss.
Eopt1trip
this shows where the threshold is for the oil pressure trip. If the oil pressure drops below this
line for more than 1 second, the engine will turn off automatically.
Eot
Engine Oil Temperature
Minimum on load oil temperature should be 50°c and a maximum of 130°c. Normal running
temperature should be around 105c.
Fp1
Fuel Pressure
This should be no higher than 3.5 bar and no lower than 2.5 bar with the engine running.
Gear
This shows what gear the gearbox is in at the time.
Gearbliprequest
This shows the request sent from the ECU to blipper solenoid.
Gearblipstate
This shows what signal the calibration is sending to the blipper solenoid.
Gearcutdogkickcount
Shows the number of times the ECU has had to briefly re-instate the power to “kick” the gear
off the dogs.

Gearcutrequest
This shows when the paddle switch has asked for a gearcut to change gear. If you experience
gear changing problems, then this can be monitored to ensure that the LIFE engine ECU is
receiving a gear cut signal.
Gearcutstate
This show what state the cut is in, in relation to what has been set in the calibration.
Geardownshiftoutput
This shows the output signal from the ECU to the downshift solenoid.
Gearshiftdecision
This is a good thing to check if you are having gear change issues, as this show you if the shift
has been ignored by the ECU, and shows you why it ignored it.
Gearupshiftoutput
This shows the output signal from the ECU to the downshift solenoid.
Gearshiftstate
Shows you what state the gearshift is in, in relation to the calibration.
Gearv
This shows the voltage that the gear position sensor is seeing, in relation to the selector
barrel movement.
Gsp
Gear system pressure. This shows the pressure in the air tank.
Gspcontrol
This shows the signal from the ECU to the compressor motor.
Lam1
Paddleswitch
This shows the reading from the exhaust lamba sensor (if fitted)
this shows the input signal from the steering wheel paddles. I.e. which paddle the driver has
used.
Revlimitactive
This shows when the rev limiter has been activated.
Rpm
Engine Speed
If constant over-revs are seen (over 10,500 rpm), then the driver needs to be advised to adjust
his driving style as this is causing damage to the engine. An over-rev should be no more than
10,800 maximum. Anything over this, then Powertec should be contacted.
Runmode
This shows whether the engine is running, stopped, cranking etc.
Runtime
This show the engine run time per session i.e. from when the engine is started, to when it is
turned off.
Syncstate
This shows the state of the injector firing. It can also be used to check whether the crank and
camshaft position sensors are working. If the camshaft sensor is not working, then the
syncstate will show 360.
Tps1
Throttle Position Sensor
This should be constant in relation to the driver’s throttle input. Also at idle, this should be
set to 4.0
Tpsclosed
this shows when the tps is in it closed position.
Vbat
Battery Voltage.
This shouldn’t drop below 11 volts when on load.

LIFE VIEW SOFTWARE
Life View is used to view engine data which has been downloaded from the ECU to a PC.
Once you have downloaded the data using LifeData following the download instructions on the previous page, the data
which is extracted from the ECU will be saved in the ‘Working Directory’ folder you set up.
There are two types of files that the computer extracts from the ECU. These are session files which have the extension
.LRD and logbook files which have the extension .LB.
The session files contain the data from a particular run or outing (from when the engine is started to when the engine
stops). The time and date that the session began is in the name of the session file. The session files contain a trace of all
the channels recorded, such as oil pressure, coolant temperature, throttle position etc.
To view the data, load LifeView. Once it has loaded, press F for file and L for load. Then find the data you are trying to
open (which will be in the working directory you set up before you downloaded it). When you get to the data, you should
see a list of session files. Highlight the one you want to load up and press enter to load it.
When the session file opens, you should see a screen like
this:
The logged channels are listed down the right hand side. To
display a trace of a channel, scroll down the list to the
channel you want to view using the up and down arrow and
then press enter to display a trace of the channel.
Some of the names are abbreviated;
eop1
ect1
= Engine oil pressure,
= Engine coolant temperature etc.
You can load up as many of these channels as you like, in order to overlay them on each other.
The colour of the trace and scale of the channels axis can be changed by right
clicking on the channel in the list on the right hand side, as shown to the right.
The logbook file contains quite a lot of information. It has an overall record which
records some important minimum and maximum values that the engine has
reached and the total time the engine has been running for since it was built or
re-built.
The logbook also records some important minimum and maximum values for
each session that the engine has run.
Loading up a logbook is similar to loading up a session file. When in LifeView,
press F for File and B for LogBook. The logbook will be stored in the same folder
as the session files, so navigate to that folder. When you get there, the logbook will not show up in the menu but if you
scroll to select using the up and down arrows, details of the logbook will come up, as shown in the picture below. Press
Enter to load the logbook.

AIM DATA SOFTWARE
To download data from your AIM data logger you must first have the Race Studio 2 Software package installed on
your laptop. This package should include Race Studio 2, Race Studio Analysis and SmartyManager.
RACE STUDIO 2
The Race studio 2 is used primarily to download the data from the data logger and save it on your PC for later analysis in
Race Studio Analysis. Race Studio is also used to configure and calibrate your data logger. Configuration shouldn’t need
to be carried out once the system is initially set up unless additional sensors are added (eg, brake pressure sensors,
suspension potentiometers). Calibration should be carried out before each race weekend or trackday meeting.
NOTE: If you are getting a message “Impossible to connect to Data Logger” this is probably due to not having the
USB Drivers installed for Aim properly. If this occurs please refer to the AIM Manual.
RACE STUDIO ANALYSIS
The Race Studio Analysis software is where you can view all of the “runs” that you have downloaded from your AIM data
logger.
Smart Manager (only applicable if AIM SmartyCam is installed)
Smart Manager is used to configure the SmartyCam to display various outputs from the data. For example the throttle
position, brake position, RPM, Speed, Lap times etc. You also carry out firmware updates for the SmartyCam through
SmartyManager.
DOWNLOADING DATA FROM THE AIM DATA LOGGE R (MXL PISTA
DASH)
As stated above you must have Race Studio 2 installed on your PC. The following
steps will talk you through how to get the data downloaded onto your PC.
1.
Connect your laptop to the car via a data download cable and power on the
device (turn on the master switch)
2.
Open Race Studio 2 and click on the “Download Data” icon on the left
hand side. This will open the pop-up download window.

Page 55
QD77-2
3.
This pop-up download window displays all of the runs currently stored on the logger with the date and time of
each run.
4.
Previously downloaded runs will not be selected automatically so you should be able to click on “Download
selected” or “Download selected runs, then clear memory”. It is recommended that you “Download selected”
and leave a backup on the logger until you have backed up the data from your PC to another storage device
(e.g., a USB key).
5.
The progress bar at the bottom indicates that the data is being downloaded.
6.
When the download progress bar reaches 100%
another window opens with the option to input
some details about the session to make it easier to
identify which session to look at later on in Race
Studio Analysis. This is an important step so
identify as many variables as possible (eg, vehicle,
driver, track, test type and add a comment). The
name for the file is automatically generated.
7.
Click the OK or Save button and the progress bar
indicates when the saving is complete.
8.
The data is now downloaded and saved on your PC
for analysis in Race Studio Analysis.

SENSOR AND ACTUATOR CALIBRATION GUIDE – ALL MODELS
GEAR ACTUATOR SETUP - SR8 AND RXC
Radical Sportscars Parts department (contact details available at the end of the Mechanics Handbook) can provide a jig
for setting the Actuator length on both the SR3 and the SR8. This is simply done as shown in the pictures below:
Note: The RXC does not need the Actuator setting.
GEAR POSITION SENSOR SETUP
To set up the Gear Position Sensor on an RXC or RXC Spyder there is not a jig. It must be set manually using the Life
Software program called “PTMon”. The sensor is located on the right hand side of the Quaife 7 Speed Gearbox See
picture below. To set the Gear Sensor, follow the steps below:





Connect a laptop (using the Life Download Lead) and turn the master switch on.
Make sure the car is in Neutral
Open PTMon and view the sensor named GearV.
Loosen the 2 retaining bolts, adjust the sensor until GearV reads 1.100V ± 0.05
Secure the sensor by tightening the 2 bolts and check the GearV is still set to 1.100V ± 0.05

To set up the Gear Position Sensor on an SR8 you must use the same Actuator Jig shown above in the “Gear Actuator
Setup” section. This Jig is made from 2mm thick material to ensure the correct positioning of the Gear Sensor on an SR8
RX. The sensor is mounted on the back plate of the Quiafe 6 Speed Gearbox. The process is explained below:




Remove the heatshield
Loosen off the 2 securing bolts (do not remove)
Place the actuator jig between the top of the sensor and the part of the gearbox case above it (See picture
below) and tighten the bolts to secure in position
Check the Gear sensor voltage using the Life Software program called “PTMon”. On an SR8, in Neutral the gear
voltage should be 1.051 ± 0.05.
Note: If not using the Actuator Jig then use PTMon to set the Neutral gear voltage as 1.051V ± 0.05 as shown in the “RXC
Gear Position Sensor Setup” section.
Note: The SR3 Gear Sensor is inside the gearbox and is set by RPE when the engine is built.
WHEEL SPEED SENSOR INSTALLATION AND SETUP – ALL MODELS
Radical Sportscars Parts department (contact details available at the end of the Mechanics Handbook) can provide a jig
for setting the wheel speed sensor. Using a pair of 13mm spanners, set the wheel speed sensor no closer to the pickup
point than the thickness of the Wheel Sensor Gauge. The pickup point is the end of the brake disc bolts on an SR3/SR8.
This is shown in the picture below. For an RXC the pickup point is the back of the drive pegs.

With the cars master switch off, remove the power to the drive-by-wire actuator (motor) by disconnecting the two-pin
SuperSeal connector.




Connect a laptop (using the Life Download Lead) and turn the master switch
on.
Open Life Mon and select the sensors that you wish to view. These sensors
areTPS1A and TPS1B. These are found under the section titled “Sensors”
and sub-section “Throttle Position”
Check that the butterflies are completely shut (visually), apply some force on
the mechanism if required.
Adjust sensor so that TPS1A (sensor on the Actuator) reads 2% (+/- 0.1%)
TPS1A – sensor on actuator

Adjust sensor so that TPS1B (Sensor on Throttle Bodies) reads 2% (+/- 0.1%)
TPS1B – sensor on bodies

Switch the Master Switch off and reconnect the power to the motor (the 2 pin SuperSeal connector that was
unplugged at the start of this procedure).
Note: if the correct position cannot be achieved on the sensor (i.e. the sensor runs out of adjustment) then the sensor is
faulty and must be replaced.
Note: with the power to the actuator re-connected tps1A and tps1B will no longer read 2%. This is normal, and is due to
the cold start procedure. When the car is warm, tps will return to around 4%.

Part 2: Setting up the Pedal Position Sensor. ppsA and ppsB
The second part to setting up the drive-by-wire throttle bodies is to set up the Pedal Position Sensor. The pedal position
sensor has 2 sensors built in to one. This is a safety mechanism, if the 2 measures ever go out of alignment, the PPS
defaults to zero as a safety precaution.
The pedal position sensor is located on the throttle pedal. Again, the Life Software program “LifeMon” is used to
monitor the two pedal position sensors during calibration. These
are found in the same way as described in Part 1.
This picture shows all of the sensors that you need to monitor in
LifeMon when setting up the Drive-by-Wire throttle bodies.

POWER STEERING SETUP AND CALIBRATION – RXC AND RXC SPYDER
There are 3 main components to the Radical EPAS (Electronic Power Assisted Steering) system that may need changing
due to accident damage or part failure. These are as follows:
1.
2.
3.
Power Steering Motor (located on the steering column)
EPAS ECU (located near the steering column)
Steering Angle Sensor (located on the steering rack)
Pt1: Replacing the Power Steering Motor and/or the EPAS ECU
There are some notes to be aware of when replacing these items to re-calibrate the system to ensure correct functioning
of the EPAS system.
If the Power Steering Motor and/or the EPAS ECU need to be replaced then the system needs to be re-calibrated in the
central position. To do this, follow these instructions:



Lift the front of the car off the ground
Put the steering wheel in the straight ahead position
Cycle the master switch 7 times.
The EPAS warning LED should now flash rapidly a number of times. This shows that the system has successfully re
calibrated.
Pt2: Replacing the Steering Angle Sensor
This steering angle sensor has two plugs on it. The signals go to both the EPAS ECU and the Aim Datalogger dash.
When replacing the steering angle sensor, it is important to set the sensor in the middle of its 5v range with the wheels
straight ahead before fitting it to the steering rack. This is done by following these steps:






Plug the sensor in to both of the plugs
Connect a laptop to the car using the Aim download lead
Open Race Studio
View the live values for the sensors and monitor the “Steering angle Channel”
Show mV values
Set the sensor to 2500mV
The sensor is now ready to install in the rack. See picture for reference.
Note, the wire coming out of the sensor points down.
Note: After the sensor is installed in the rack, follow the instructions above
in Pt1 to Re-Calibrate the system.

TROUBLESHOOTING UNEQUAL BANK TO BANK RUNNING ON V8 ENGINES
1.
Are the throttle bodies out of balance?
Check and rebalance using a syncrometer. If a syncrometer is not
available then manually pick the revs up and listen for a change in
engine note as both banks begin firing. At this point both sets of
exhaust primaries should warm up together.
2.
Are the plug leads and coils connected in the correct
orientation?
Please see the diagram of the plug lead and cylinder layout.
The engine runs wasted spark ignition so leads 1&4 can be
installed in either orientation as can leads 2&3.
3.
If the spark plugs have recently been changed, are the caps missing from the plugs?
4.
Download the ECU data and email in to the factory. If the car is fitted with a Life ECU the data can be
downloaded and analysed. Software and instructions on how to do this can be found in the download section of
www.radicalperformanceengines.com.
The “syncState” channel will show if the ECU is receiving a signal from the cam sensor. The channel will display
720° when the engine is running with a working cam sensor. It will display 360° if the engine is started and the
ECU cannot detect the cam sensor.
5.
Carry out a compression and leak down test on all 8 cylinders and send the results to the factory. Ensure that the
throttle is held wide open and the ignition is switched off. 10-12 engine rotations should be enough to produce
sufficient readings.
6.
Check both banks exhaust systems for blockages or restrictions, especially if it is a non-Radical system.
7.
Check the inlet cams in both banks are turning by removing the cam sensor from both banks of the engine. With
the ignition switched off crank the engine over and look to see if the cams are turning.

PADDLE SHIFT TROUBLE SHOOTING GUIDE
As of 2010, all radical cars that have the paddle shift option fitted new from the factory, will be fitted with a closed
loop paddle shift system that is controlled by the engine ECU.
This system relies on a magnetic gear position sensor fitted internal on SR3 Hayabusa engine, and on the end of the
gearbox, nearest the rear of the car, on the SR8, and SR3 SL
Most gear change problems can be diagnosed by downloading the engine management data, and viewing the
items listed below paddleswitch
This parameter shows when the switch has been operated by the driver, and which paddle the
driver pulled.
gear
This shows what gear the gearbox is in
gearv
This shows the signal that the sensor is sending back to the ECU. It is in direct relationship to the
movement of the selector barrel. This can be used to check for interference to the sensor
It can also be used to determine gear change actuator operation. If the paddleswitch has been
operated but this channel shows no signs of change, then the gear change actuator isn’t moving
or there is a fault with the mechanic side of the gearbox i.e. selector mechanism is jammed.
tps
This shows throttle position. This can be viewed to determine whether the throttle is being
blipped on the downshift.
If there is no jump in the tps trace when the downshift paddle is being pulled, then 95% of the
time, it won’t downshift.
gearshiftdecision
This is a vital parameter to view when diagnosing paddle shift problems, as this shows you if the
ECU has disallowed a gearshift.
There a number of settings in the ECU that are used to control the operation of the shift system.
An example is TPS. If the throttle is over 20% when the downshift paddle is pulled, then it won’t change down. This is to
prevent over-revving the engine.
gsp
This shows the pressure of the paddle shift system. If this is too low, the system won’t operate.
(This will show up in the gearshiftdecision data).
It can also be used to determine a fault with one of the actuators. For example, if the gsp value
drops when the paddle shift is operated, it indicates that the distribution valve block is
operating. If the gsp doesn’t drop, then the valve block is not operating. (
gsp control
This shows when the ECU has asked for the compressor to be turned on. If this is showing "on",
but the compressor is not operating, then there is a problem with either the compressor relay,
the connections, or the compressor itself is not operating.
rpm
Is the rpm is over 9200, the gear will disallow a downshift. This is to prevent damage to the
engine.

this channel is viewed to check the electrical supply to the system. (complete car electrical
system). If the charging system is not working, the paddle shift system (and many other
systems on the car) won’t operate correctly.
Below are listed some other common problems that will affect the shift operation
PADDLE SHIFT TROUBLE SHOOTING GUIDE - UPSHIFT
wiring to steering wheel paddles
This can be caused if the driver removes the steering wheel aggressively
without disconnecting the dash plug
Gear change actuator adjustment (as described above)
System leaks
Gear change valve block faulty
Paddle switch wiring on steering wheel damaged
system changes gear without paddle operation
this can be caused by damage to the steering wheel paddle wiring.
Both upshift and downshift will affected by bad electrical connections, poor battery voltage, air leaks in the system, and
interference or damage to the gear position sensor.
rd
th
Any problems that are related to a specific gear i.e. works 3 to 4 , but not any others, would usually indicate a
mechanical fault within the gearbox.
Above all, any gear change issues should be addressed immediately, as failure to do so will cause gearbox and potentially
engine damage and invalidate the engine warranty.

throttle cable is slack
This must be kept adjusted as the blipper actuator pulls on the cable to
achieve the throttle blip
gear shift actuator operation
The gear change actuator must be able to rotate freely on the bearings
at both ends, but must have NO movement in the horizontal direction.
i.e play in the bearings
gear change actuator adjustment
This must be set so that the actuator shaft has the same amount of
travel in both directions.
This can be set using a jig that can be obtained from Radical, or by using
a steel ruler to measure the amount of travel. Adjustment is made using
the rod end on the end of the shaft.
valve block faulty
This unit controls both the downshift part of the gear change actuator
operation, and also operates the throttle blipper actuator.
