Link G4X WRXLink WRX2X PlugIn ECU - Subaru WRX/STI (GC8) V1-2
Ditch the limitations of the factory ECU with the Link G4X WRXLink WRX2X plug in ECU. Built by Link, this unit gives tuners full control over fuelling, ignition and auxiliary functions while keeping installation simple, since the PCB fits discretely inside your original ECU enclosure. It's designed specifically for the Subaru WRX and WRX STI.
This listing covers the Subaru WRX and WRX STI (GC8) V1-2 models, SKU 226-4000. No cutting or modification of the factory wiring loom is required, and the board is designed as a direct swap into the stock ECU housing.
Note: A MAP sensor is not included and will need to be sourced separately. Owners wanting extra inputs and outputs beyond the built-in connector can add Link's XS Expansion Loom.
