Introduction
Thank you for purchasing your Vi-PEC Plug-In Engine Control Unit (ECU). Vi-PEC VX ECUs are an
advanced, fully programmable microprocessor controlled Engine Management System.
The VX software platform boasts an impressive list of features giving a new level of user adjustment.
This flexibility allows the tuner to have complete control over the engine management system. VX
software employs high resolution fuel and ignition tables with configurable load and RPM centres. When
coupled with up to six dimensional fuel and ignition mapping, barometric pressure compensation and
intake air temperature correction this gives an unprecedented level of tuning accuracy. All Vi-PEC VX
ECUs are in field upgradeable, there is no need to return the unit for software updates.
All Vi-PEC VX Plug-In Engine Management Systems are designed with flexibility and ease of installation
in mind. Vi-PEC Plug-In systems are designed to either replace the circuit board inside the factory ECU
enclosure, or entirely replace the factory ECU. This provides an invisible install that requires minimal
modification to vehicle wiring and ECU mounting.
Vi-PEC Engine Management Systems are designed with the final result in mind. Not only do they boast
an impressive range of performance features, but are designed with a focus on safety, reliability and
drive-ability. However, the ultimate success of your engine management upgrade is determined by how
well the system is installed and tuned.
Installing and tuning any after market engine management system is not to be taken lightly. VX ECUs
give the tuner the control & flexibility that only top after-market engine management systems in the world
can provide. While every effort has been made to keep VX ECUs as user friendly as possible, it should
be recognised that added features bring added complexity.
The complete setup of your ECU can be divided into two important tasks:
1. This manual covers the installation of your VX ECU. While it is not strictly essential that this work is
performed by an automotive electrician, the knowledge and tools available to these professionals
makes it highly recommended. Regardless of who does the installation, it is of utmost importance
that instructions provided in this manual are followed exactly throughout the installation.
2. Once the VX ECU has been installed it will need to be tuned using a laptop computer with Vi-PEC
Tuning Software software. Information on the configuration and tuning of the VX ECU is detailed in the
online help section of Vi-PEC Tuning Software. VX ECUs are shipped pre-loaded with a base
configuration that should be close enough to get most engines running after a few application specific
adjustments have been made. While hearing the engine running on the new ECU for the first time is
always a satisfying feeling, it is important to realise that the job is not complete. The amount of
tuning performed and the experience of the tuner are the two most important factors in determining
how happy you will be with your engine management system.
1.1
Safety Notice
Your Vi-PEC Plug-In ECU is designed to enhance the performance of your vehicle. However in all
cases, your vehicle must be operated in a safe manner. Do not tune your vehicle while operating it on
public roads. Obey road rules at all times.
WARNING!
Failure to follow all installation and operating instructions may result in
damage to the Vi-PEC ECU, personal injury, or harm to property.

Pre-Installation
Before installing theVi-PEC VX ECU into the vehicle some pre-installation checks must be performed.
2.1
Board Switch Settings
Some Vi-PEC VX ECUs require switches on the board to be set before installation.
2.1.1
Mitsubishi Lancer Evolution IV-VIII
The location of the intercooler spray relay pin changed between models. Set the provided jumper in the
correct location for your model.
2.2
Injector Impedance
Injector impedance is important and needs consideration before installing the ECU.
2.2.1
Mitsubishi ECUs
The Mitsubishi VX Plug-In ECU is NOT designed to be used directly with low impedance injectors.
All models this ECU is designed for are fitted with low impedance injectors from factory. Current through
low impedance injectors is reduced by the use of factory fitted injector ballast resisters. This means
that the ECU is plug-in compatible with factory fitted injector combinations on all models. DO NOT
remove the factory fitted ballast resisters.

PlugIn Installation Manual
Installation
This guide provides information on correctly and safely installing your new Vi-PEC VX Plug-In ECU.
3.1
ECU Handling Procedures
WARNING!!!
The following installation process will require handling of both the Vi-PEC ECU
and factory ECU. Both of these are highly sensitive to electrostatic discharge
and are easily damaged. Follow the anti-static precautions given in this
manual carefully to avoid damaging electronic components. Warranty claims
for ECUs damaged by electrostatic discharge will NOT be accepted.
ANTI-STATIC HANDLING GUIDELINES
Your body builds up an electrical charge as you move around. This charge can reach very
high voltages. Whenever given the opportunity this energy will attempt to discharge
(usually through your finger tips!). This can be fatal to most electronic components. Most
people have experienced an electrostatic discharge when they step out of their car or
touch a metal bench top.
1. The following guidelines describe precautions that can be taken to reduce the possibility
of damaging your ECU:
2. Work only on a conductive surface. A clean steel bench is suitable.
3. Always wear a wrist strap that is electrically connected to the conductive working
surface.
4. Touch the working surface regularly.
5. Do NOT touch components on the circuit board.
6. Where possible, only handle the ECU by its plastic header.
7. Do NOT carry the ECU around without anti-static packaging.
8. Do NOT touch the bare terminals in the ECU header.
Observing the above procedures will minimise the chance of damaging the ECU. Note that
failure due to static damage often does not appear until well after it was caused.
3.2
Fitting the ECU
Audi TT 8N
Information is provided to assist in fitting the ECU into the vehicle.
3.2.1
Fitting a Mitsubishi ECU
The following steps outline the installation procedure:
1. Remove the factory ECU from the vehicle: Ensure the key is in the OFF position. The factory ECU is
located on the left A pillar about 30cm above the floor. Unplug the wiring harness from the factory
ECU. Remove the 6mm bolts (10mm socket) that retain the ECU and remove the ECU from the
vehicle. DO NOT touch the exposed pins in the factory ECU connector.
2. Remove the factory ECUs circuit board from its enclosure: Ensure you are following the given anti© 2012 Vi-PEC
Installation

static guidelines and ARE WEARING A CONDUCTIVE WRIST STRAP connected to a conductive
working surface. Using four small flat bladed screwdrivers, carefully pry apart the four plastic lugs
retaining the ECUs header plate into the case. Some force may be required to remove the circuit
board from the case as it may be partially glued to the inside. Remove the circuit board by removing
the retaining screws. Hold it only by the plastic header and place it aside.
3. Connect the ECU USB tuning cable and the expansion loom if required.
4. Fit the Vi-PEC Plug-In ECU, there are several options depending on the vehicle:
EVO IV to VIII - If fitting to a short case, CAREFULLY snap the PCB extension off. It may be
necessary to use a sharp knife to first score the break off points. Place the factory ECU in the
packaging your Vi-PEC ECU came in for its protection. After inserting the Vi-PEC ECU into the OEM
case, carefully fit the supplied aluminium end plate to the enclosure. Make sure the end plate is fitted
to allow any cables to exit on the left side of the header.
EVO IX - Place the factory ECU in the packaging your Vi-PEC ECU came in for its protection.
Carefully fit the supplied aluminium end plate to the enclosure. Make sure the end plate is fitted to
allow any cables to exit on the left side of the header.
All Others proceed to step 5
5. Install the Vi-PEC ECU circuit board into the enclosure, then fit the enclosure into the vehicle.
6. Connect the ECU to the factory wiring loom.
7. Do NOT attempt to start the vehicle. Proceed to read through the remaining sections of this manual
first.

PlugIn Installation Manual
Additional Sensors
VX Plug-In ECUs offer various options for the installation of additional sensors and devices. As a
minimum it is recommended that all ECUs are installed with a Manifold Absolute Pressure (MAP)
sensor and Intake Air Temperature (IAT) sensor. These parts can be purchased if required from your
nearest Vi-PEC dealer.
4.1
MAP Sensor
It is important that the pressure source for a MAP sensor be taken from a stable pressure source after
the throttle body. It is common to 'T' into the fuel pressure regulators pressure signal. Do NOT share
this signal with other devices such as boost gauges or blow off valves.
4.1.1
Mitsubishi Lancer Evolution IV - VIII
The Vi-PEC VX EVO Plug-In ECU supports several options for fitting of a MAP sensor. Any one of the
following options can be used:
1. The factory MAP sensor - Some models are fitted with a factory MAP sensor, this is wired to AnVolt
1. The correct calibration will need to be determined due to variations in sensors across different
models.
2. MAP Through AFM – The factory AFM wiring can be used to install a MAP sensor.

3. MAP Through Expansion Connector - The expansion connector provides power, ground, and analog
channels for the connection of a MAP sensor.
Make sure that the correct An Volt channel has been selected as MAP sensor in Vi-PEC Tuning
Software and a MAP calibration has been performed before attempting to start the vehicle.
4.2
IAT Sensor
It is highly recommended that an IAT sensor be fitted in all applications to provide an input for correction
of fuel and ignition based on the engines air charge temperature.
An IAT sensor should be fitted in the intake system in a location that accurately represents intake
temperature. The most common location is just prior to the throttle body. Installing in the manifold is
not recommended due to heat soak issues. A fast response sensor must be used in all forced induction
applications.
4.2.1
Mitsubishi Lancer Evolution IV - VIII
From factory, models supported by the Vi-PEC VX EVO IV-VIII Plug-In ECU are not fitted with a suitable
IAT sensor. The Vi-PEC VX EVO IV-VIII Plug-In ECU supports several options for fitting of an IAT
sensor. Any one of the following options can be used:

Additional Sensors
11
1. IAT Through AFM – The factory AFM wiring can be used to install a MAP sensor. An Temp 2 is wired
to the AFMs temperature sensor. Refer to the MAP sensor wiring information above.
2. IAT Through Expansion Connector - The expansion connector provides ground and temperature
channels for the connection of an IAT sensor. Wire the sensor between the Ground pin and an An
Temp channel pin. Note that not all ECU models have spare temperature channels.
3. IAT Through Fuel Temperature Pin – Pin 77 is connected to An Temp 3. On some models this is
used to measure fuel tank temperature. You can wire an IAT sensor between this pin and pin 92
(sensor ground). Refer to Appendix B for pin numbering. Additional terminals to fit the factory header
are supplied with the ECU.
4.3
Expansion Connector
The expansion connector is provided to allow easy connection of additional ECU inputs. An “expansion
cable” needs to be purchased from your Vi-PEC dealer.
Important points when wiring to the expansion connector:
Do not overload the +5V Out pin. Although this is protected against ECU damage the +5V out signal
also provides power for other sensors.
Do not connect the ground pin to chassis ground. This could cause ground loops and introduce
unnecessary interference. Use this pin only to ground external sensors that are isolated from chassis
ground.

PlugIn Installation Manual
Pre-Start Configuration
Before starting the vehicle, important pre-start configurations need to be made.
6.1
Firmware Version
It is recommended that the Vi-PEC VX ECU is running the most up to date firmware. Firmware version
information can be obtained by connecting to the ECU with Vi-PEC Tuning Software and selecting 'ECU
Information' under the Help menu.
The latest firmware can be downloaded from our website with Vi-PEC Tuning Software.
It is recommended that this is performed by an experienced Vi-PEC dealer as new features may need to
be properly configured.
The firmware can be updated by selecting 'Update Firmware' under the 'ECU Controls' menu in Vi-PEC
Tuning Software. Follow the on screen instructions to complete the firmware update process.
6.2
Base Configuration
All VX Plug-In ECUs are shipped with base configuration settings. Note that these are provided to
reduce initial setup and tuning times. They are NOT recommended tuning values. Vi-PEC Tuning
Software includes base configurations for various models. Download the appropriate base configuration
into your ECU with Vi-PEC Tuning Software by connecting to the ECU (described in the Connecting To
Vi-PEC Tuning Software section of this manual), then selecting 'Open' under the 'File' menu. Select the
appropriate .pcl file and then select 'Open'. Downloading large configuration files can take up to a few
minutes. Be patient and acknowledge any messages Vi-PEC Tuning Software shows.
6.3
MAP Sensor Calibration
At key on and engine not running the Manifold Absolute Pressure (MAP) Sensor should always match
the Barometric Absolute Pressure (BAP) Sensor. As well as providing altitude correction, the BAP
sensor also allows the MAP sensor to be calibrated prior to tuning.
Vi-PEC VX ECUs use an on-board barometric sensor that is calibrated prior to dispatch. This ensures
that all Vi-PEC Tuning Software Tuning Software programs (pcl Files) give a consistent state of tune
throughout the ECU range. This allows a PCL file to be transferred between VX based ECUs giving an
equivalent state of tune providing all factors affecting volumetric efficiency are equal.
Without the ability to calibrate all the available types of MAP Sensors to the BAP Sensor there would be
significant affects on the accuracy of the resulting tune, especially when tuning with Manifold Gauge
Pressure (MGP) as a load index.
To calibrate the MAP sensor:
1. Connect a laptop/notebook PC to the ECU and connect to the ECU using Vi-PEC Tuning Software.
2. Under the Analog Channels menu, select the An Volt channel that has been wired to the MAP
sensor. Select the correct MAP Sensor Type.
3. Under the 'Options' menu, select 'MAP sensor calibration'.
4. Follow the on screen instructions.
5. Select the 'Analog Inputs' tab in the runtime values section of Vi-PEC Tuning Software (lower part of
the screen).
6. Compare the MAP and BAP values and ensure they have a similar reading (within 1 kPa).
7. Perform a 'Store' by pressing F4.

TPS Calibration
The Throttle Position Sensor (TPS) is used by the ECU to calculate various engine management
parameters used by functions such as idle speed control,acceleration enrichment and motor sport
features. It is important that the ECU knows when the throttle is open and closed (or part way in
between). The following procedure calibrates the ECU to match the TPS:
1. Connect a laptop/notebook PC to the ECU and connect to the ECU using Vi-PEC Tuning Software.
2. Under the Analog Channels menu, ensure that the correct An Volt channel is set to 'TPS (Main)'.
Refer to the pin functions section of this manual for details.
3. Under the 'Options' menu, select 'TPS calibration'.
4. Follow the on screen instructions.
5. Select the 'Analog Inputs' tab in the runtime values section of Vi-PEC Tuning Software (lower part of
the screen).
6. Ensure the Throttle Position value reads 0% when the throttle is closed and 100% when fully open.
7. Perform a 'Store' by pressing F4.
6.5
IAT Sensor Selection
This section only applies when an Intake Air Temperature (IAT) sensor has been wired and fitted to the
intake system. It is important that the ECU is calibrated to match the sensor installed in the engine.
This procedure is as simple as selecting the correct sensor type as follows:
1. Connect a laptop/notebook PC to the ECU and connect to the ECU using Vi-PEC Tuning Software.
2. Click on 'Analogue Channel' in the configuration tree.
3. Select the An Temp channel the sensor has been wired to.
4. Ensure that channel (and only that channel) is set to 'Inlet Air Temperature'.
5. Select the correct 'Temp Sensor Type'.
6. Select the 'Analog Inputs' tab in the runtime values section of Vi-PEC Tuning Software (lower part of
the screen).
7. Ensure that IAT reads the correct temperature.
8. Perform a 'Store' by pressing F4.
6.6
Input and Output Setup
As the Vi-PEC VX Plug-In ECUs are designed to run several models there are a few items that must be
set-up to make the ECU specific to your model.
The Pin Functions section of this manual gives a list of the functions of each channel based on the
target vehicle.
It is the tuners responsibility to make sure that the following channels are set-up correctly for the vehicle
model the ECU is fitted to:
All Auxiliary Output Channels
Use the 'Test On' or 'Test PWM' (at 10 Hz) functions to test the wiring of channels.
All Digital Inputs
Look at the Digital Inputs runtime values (lower section of the Vi-PEC Tuning Software screen) to confirm
each channels operation.
All Analogue Volt and Temperature Inputs
Look at the Analogue Inputs runtime values (lower section of the Vi-PEC Tuning Software screen) to
confirm each channels operation.

PlugIn Installation Manual
Trigger Calibration
The following instructions assume that all pre-start set-up instructions given in previous sections have
been completed. Only after all pre-start checks have been made should an attempt be made to crank
the engine. The following steps must be performed before an attempt is made to start the engine to
ensure the VX ECU is calibrated to precisely measure engine position.
1. Connect the ECU to Vi-PEC Tuning Software.
2. Select 'Fuel', then 'Fuel Set-up':
a. Set ‘Injection Mode’ to OFF. This will prevent the engine from trying to start while the triggers are
calibrated.
b. Perform a Store (press F4) to make sure fuelling is not re-enabled if power to the ECU is lost.
3. Click on ‘Triggers’ then ‘Calibrate Triggers’.
4. Perform the correct trigger calibration procedure specific to your vehicle as described in the Vi-PEC
Tuning Software online help (Press F1).
Note that trigger calibration must be performed again once the engine is running. Due to the
acceleration and deceleration of the crankshaft at low speeds, an inaccurate measurement of engine
timing is usually made. Also it is often harder to see timing marks with a timing light at slow engine
speeds. Trigger calibration should be checked again at between 2000-4000 RPM where engine speed is
stable and a more consistent timing reading can be obtained.

17
First Time Startup
After performing all set-up instructions given in previous sections, including trigger calibration, the engine
is now ready to be started. The following procedure should be used for first time start-up.
1. Turn the ignition key OFF then ON. The fuel pump should prime momentarily upon power up.
2. Connect the ECU to Vi-PEC Tuning Software.
3. Access the runtimes values by pressing the F12 Key, click the 'Analog' tab:
a. TPS – spans from 0 to 100% when throttle is pressed. If not, perform a TPS Calibration.
b. MAP – should read approx 101 kPa (at sea level) with the engine not running. If not, check the
MAP Sensor Type setting and perform a MAP Calibration.
c. ECT – should read current engine temperature.
d. IAT – should read current intake air temperature.
e. Digital Inputs (click the 'Digital' tab) – Operate switches connected to any digital inputs while
watching the runtime value to ensure they operate as expected.
4. Rectify any faults found in Step 3.
5. Locate the 'Master Fuel' setting. This can be found in the ECU Settings Menu under: Fuel > Fuel
Setup > Fuel Main.
a. This will need to be adjusted during or just after start-up.
6. Crank the engine until it starts. Some throttle may be required for first time start-up due to imperfect
tuning. If necessary adjust the Master setting to enrich/lean the engine (increase to enrich).
7. If the engine fails to start after several attempts, do not crank it endlessly. Stop and determine the
problem before continuing.
8. Check the Trigger Error Counter (found under the Triggers runtime values tab). If this value increases
during cranking/running then there is a trigger setup fault. It is not unusual for this number to count
one or two on the first engine revolution.
9. Once the engine starts, adjust the ‘Master’ (under fuel settings) setting to achieve best possible
running.
10.The engine should now be allowed to fully warm up. It may be necessary to readjust ‘Master’ several
times to maintain smooth running. Don’t forget to keep an eye on engine temperature.
11.Once the engine is warmed up and running well, perform another trigger calibration (known “as setting
the base timing”).
12.Perform a Store by pressing F4.
7.1
Final Checks
To avoid potential engine damage and wasted time, the adjustments presented in the following sections
must be made before attempting to start the engine.
For further help on any of the settings discussed below, consult the online Help in the Vi-PEC Tuning
Software Tuning Software. Online help can be invoked by pressing F1, or right clicking any item and
selecting ‘What’s this?’.
Pre-set-up Checks
Before attempting to configure the ECU, ensure the following tasks have been completed:
1. Ensure the ECU and all associated components are connected and correctly wired/installed.
2. Fully charge the vehicle’s battery, as the engine will be required to be cranked during the set-up
procedure.
3. Check all oil and water levels are correct.

7.2
Essential Tuning Adjustments
It is assumed that at this stage all set-up procedures described in previous sections have been
completed and the engine is running. The following steps detail correct set-up procedures for some of
the more critical ECU parameters (note that MAP Sensor Calibration should have already been
completed by now):
Injector Voltage (Dead-time) Correction
There is always a delay between the injector being energised and the injector actually opening.
Likewise, there is a small delay between the injector being de-energised and the injector closing. The
opening time is considerably longer than the closing time, however the overall result is that less fuel will
flow for a given pulse width than would be expected with an 'ideal injector'. To compensate for this the
injector pulse widths are increased to compensate for this 'dead-time'. The dead-time for a given injector
is a function of the battery voltage, differential fuel pressure and the type of injector driver (saturated or
peak and hold). A typical dead-time at 3 Bar differential fuel pressure and 14 volts is just under 1ms (ms
= millisecond = 1 thousandth of a second).
In applications with a linear 1:1 fuel pressure regulator (i.e. not a rising rate regulator), the differential fuel
pressure (difference between manifold pressure and fuel pressure) will be constant. Therefore the only
variable that is changing will be the battery voltage (this changes with electrical load and sometimes
engine speed). Without correction, the changes in dead-time will cause the engine to run lean when the
voltage drops. If the Injector Voltage Correction is properly set-up then changes in the battery voltage
will not affect the air/fuel ratio.
The injector dead-time table allows the dead-time for different battery voltages to be entered. The values
represent the dead-time in milliseconds. These should increase with falling system voltage.
Injector dead-time for a particular set of injectors can be determined using a flow bench or on a running
engine.
To determine the injector dead-time using a flow bench, the injectors need to be operated at the intended
operating pressure (normally three bar) and at a constant duty cycle as well as a set voltage. Vary the
supply voltage to the injector and measure minimum pulse width at which the injectors will flow for a
particular voltage. This is the required dead-time for that injector at that tested voltage.
To determine injector dead-time on a running engine, with the engine fully warmed and operating at
stable air/fuel ratios (a very precise AFR meter is required – a narrow band O2 sensor will not suffice),
electrical drain needs to be applied to the system; the preferred method is disconnecting the alternator
main fuse. Battery load testers are also useful here too.
Watching the air fuel ratios change while the battery voltage drops, the dead-time table can be trimmed
to maintain the same stable air/fuel ratio. Injector dead-time can be viewed as a row graph. A smooth
curve needs to be maintained at all times.
NOTE: any change to the fuel pressure or injectors will require a recalibration of the injector dead-times.
Master
Master should be set so that the numbers in the middle of the fuel table end up around a value of 50.
This is to allow sufficient span of the numbers in the main fuel table.
