VR4LINK – VR4X

Free yourself from the constraints of the factory ECU.

The Link G4X VR4Link VR4 PlugIn ECU fits the Mitsubishi VR4 4G63T. The ECU PCB fits discretely inside the original factory enclosure.

Installation of Link’s VR4 ECU is a breeze, with no alteration of the factory wiring loom required. A built-in connector (or pins in some models) provides additional inputs and outputs such as oil pressure inputs or anti-lag / logging switches.

Factory features are supported – see Features for any exceptions.

Includes Integrated 4 Bar MAP Sensor.
