Free yourself from the constraints of the factory ECU
The Link G4X WRXLink (3-4) WRX4X PlugIn fits the Subaru WRX & STI V3-4. The ECU PCB fits discretely inside the original factory enclosure.
Installation of Link's Subaru WRX4X ECU is a breeze - no alteration of the factory wiring loom is 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.
MAP Sensor not included.
Need more inputs and outputs?
The XS Expansion Loom offers the ability to add additional inputs & outputs on our range of plug-in ECUs.
