Link G4X Subaru WRX9X Plug-In ECU – WRX Version 7 / 8 / 9

The Link G4X Subaru WRX9X Plug-In ECU gives you modern standalone engine management while retaining the convenience of a genuine plug-in ECU.

Designed specifically for the Subaru WRX Version 7 to Version 9 with EJ20 engine, the WRX9X fits directly into the factory ECU location using the original mounting points, wiring loom and ECU connectors.

No replacement engine loom or adaptor harness is required. The ECU is designed to work with the factory wiring while retaining supported original vehicle functions and maintaining a clean, factory-style installation.

A startup map is included to help get the engine running ready for final setup and calibration.

The WRX9X uses the same processor, firmware and PCLink software as the rest of the Link G4X range and includes the standard G4X feature set.
