Pre-Installation 2 7 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.
3 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.
Installation 9 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.
4 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.
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.
5 PlugIn Installation Manual PC Tuning VX ECUs require PC/laptop tuning using the Vi-PEC Tuning Software Tuning Software application running on a Windows based computer. Vi-PEC Tuning Software may be downloaded from www.vi-pec. com. Note that when new versions of Vi-PEC Tuning Software are released they are posted on the website and may be downloaded at no cost. Also note that VX ECUs must be used with the correct version of Vi-PEC Tuning Software. IMPORTANT! The VX ECU has on board USB.
PC Tuning 13 dialogue will open. Select the correct COM Port number from the drop down list or select auto for automatic com port detection. 6. Vi-PEC Tuning Software offers both mouse and keyboard control. To establish a connection between the PC and ECU press the F3 key. The same process can be used to disconnect. If a successful connection is established, Vi-PEC Tuning Software will download settings from the ECU, otherwise you will be warned that an error has occurred. 7.
6 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.
Pre-Start Configuration 6.4 15 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.
6.7 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.
First Time Startup 7 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.
PlugIn Installation Manual 1. Make sure your laptop battery is fully charged or plugged in to mains power. 2. Connect the ECU to your laptop and connect to Vi-PEC Tuning Software Tuning Software as described in the 'Communicating with your ECU' section of this manual. 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.
Pin Functions 8 Pin Functions A list of pin functions is provided, this is useful when configuring your ECU through Vi-PEC Tuning Software. 8.
9 PlugIn Installation Manual Pinouts Pin information is provided to assist when troubleshooting. All pinouts are looking into the ECU (wire side). 9.
Known Issues 10 21 Known Issues All plug-in ECUs are fully tested on a range of relevant vehicles, although there are often variations that have not been tested. For this reason issues can arise. Please contact your nearest Vi-PEC dealer when suspecting a compatibility issue. 10.1 Mitsubishi Lancer Evolution IV - VIII There are currently no known issues.
