Link G4+ VR4Link

Free yourself from the constraints of the factory ECU.
 
The Link G4+ VR4Link VR4+ PlugIn 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.

Need more inputs and outputs? 
The XS Expansion Loom offers the ability to add additional inputs & outputs on our range of plug-in ECUs. 

Includes Integrated 4 Bar MAP Sensor.
