The range includes WRXLink plug-in ECUs such as the WRX2X, WRX6X, WRX104X, V10 and V11, plus G4X versions.

Choosing the Right Part

Link plug-in ECUs are matched to a specific chassis code and model year range, so identify your car before ordering.

Chassis code: GC8 (V1-2, V3-4, V5-6), GDA/GGA/GDB, or GR/GV/GH/GE.
Model year: GDB-era cars are split into MY04-06, MY06-07 and earlier 7-9 variants, and the later chassis covers MY2007-2011.
Model designation: product titles list the applicable WRXLink part, such as WRX2X, WRX6X, WRX104X, V10 or V11.
Platform: some listings are G4X versions, so check the listing for the exact platform supplied.

Check the fitment details on each listing to confirm your chassis code before ordering.

Installation & What You'll Need

Plug-in ECUs are designed to connect to the factory engine loom connectors for the listed chassis, but the ECU still needs to be configured and tuned for your engine and any modifications. Installation by a professional is recommended, and tuning should be carried out by an experienced tuner using appropriate equipment. Keep your original ECU aside if you may need to return the car to standard.
