The Link G4+ range of engine management systems are already well known for delivering class-leading performance without sacrificing factory levels of drivability.
Watch our video on why we'd always use a link over a stock ECU. More power, more safety and better to actually drive:
The G4+ plug-in ECUs are designed to be the most complete plug-in solution yet.
This Mitsubishi Evolution plug-in ECU will save you time and money as it will plug straight into the vehicle’s original wiring loom without the need for messy adaptor harnesses. It replaces the original circuit board inside the factory ECU enclosure and mounts using the factory brackets.
This Link G4+ Evo 1-3 plug-in ECU is suitable for the models listed below:
- Mitsubishi Lancer Evolution 1-3 (manufactured 92-96 with chassis number CD9A & CE9A)
Once the installation is complete, the Link G4+ allows a good tuner to achieve an optimal state of tune to get the most out of any combination of modifications.
All Link G4+ plug-in ECUs come with a base map. While these maps are designed to help save time for you and your tuner, it is essential that these are used simply as a starting point for further tuning.
The engine can easily be converted to speed density by removing the air flow meter and instead using a suitable MAP and air temperature sensor. Likewise, this ECU can also be setup to control boost electronically with in-cabin adjustment. This eliminates the need to purchase a separate electronic boost control system.
The vehicle’s original sensors & actuators are used except for the following exceptions:
- MAP sensor – An on board 4.0 Bar (up to 44psi) MAP sensor is supplied with the VR4 G4+ plug-in. For boost pressures above 44psi a higher reading external MAP sensor may be purchased (we have many types in stock). These can be connected by modifying the factory loom to use existing wiring that was previously used for the mass airflow sensor. Alternatively, an external MAP sensor may be connected to the ECU’s expansion connector via an XS Loom. The mass airflow sensor is not required.
- Inlet Air Temp Sensor (IAT) – An IAT sensor (sold separately) should be installed just prior to the throttle body. This can be connected using existing wiring that was previously used for the mass airflow sensor.
- Electronic Boost Control – The factory boost solenoid control wiring is used, however the boost solenoid itself must be upgraded on applications using an external wastegate or elevated boost levels. If in-cabin boost adjustment is required then a boost knob or boost switch is also needed. These can be connected to the expansion connector of the ECU using the XS Loom.
- Injectors – The G4+ plug-in is designed to be used with high impedance injectors. Low impedance injectors may only be used with ballast resistors. Luckily, the E38A/E39A VR4 has low impedance injectors with a factory-fitted ballast system so no changes are necessary. DO NOT remove the factory fitted ballast resistors unless the injectors are changed to a high impedance type.
Extra sensor inputs
The expansion connector on the Link G4+ board is provided to allow the easy connection of additional ECU inputs. The expansion connector provides the following:
- 5V Supply
- Sensor Ground
- 1 digital inputs
- 2 analogue voltage inputs
- 1 analogue temperature inputs
These may be used for functions such as driver adjustable boost control, switchable fuel/ignition maps, wideband lambda input, external MAP sensor, IAT sensor, fuel pressure and oil temp/pressure.
Outputs
Any redundant outputs may be reconfigured & used for alternative uses. Examples include, shift light, water injection, NOS control etc.
