Link WRXLink WRX6X - Subaru WRX/STI (GC8) V5-6
Break free from the limitations of the factory ECU with the Link G4X WRXLink WRX6X, a plug-in ECU built specifically for the Subaru WRX & STI (GC8) V5-6. The Link G4X platform gives tuners full control over fuelling, ignition and factory features without the compromises of a piggyback solution, making it a proven choice for road and motorsport builds alike.
This listing covers the WRX6X PlugIn ECU for the Subaru WRX and WRX STI, GC8 chassis, V5-6 models. The new ECU PCB fits neatly inside the original factory enclosure, so there's no cutting or splicing of the factory wiring loom required for installation.
Note: A MAP sensor is not included with this ECU. Additional inputs and outputs are available via a built-in connector or pins depending on model, with further expansion possible through the separately available XS Expansion Loom.
