Subaru WRX & STI V1-2 WRXLink - WRX2X

The WRXLink - WRX2X G4X PlugIn ECU is engineered for Subaru WRX V1-2 EJ20 models produced from 1992 to 1996. This unit installs directly into the factory OEM enclosure, requiring no modification to the original wiring harness. It features advanced G4X engine management technology, including up to 6D fuel and ignition mapping, precision closed-loop cam control, and sequential fuel delivery. Designed exclusively for manual transmissions, it supports most factory features while offering extensive I/O expansion. Note that E-Throttle functionality requires specific hardware modifications.
