Description
A plug-in ECU covering the widest range of Subaru WRX/STI generations, from the 2007-2014 GR/GV/GH/GE chassis through to the 2015-2021 VAB/VAF chassis (turbocharged EJ20/EJ25), fitting inside the factory OEM enclosure with no wiring loom alterations required. Due to the many model variations, PC Link's Configuration Memo text should be checked carefully before tuning.
Compatibility

Requirements & notes
- Confirm the connector matches the header shown in product photos before ordering — check the supported models list or contact a Link ECU reseller or tech support if unsure.
- Air temp sensor highly recommended.
- Supports DCCD, hill start assist, SI-Drive, cruise control, cam control and ABS on most models.
- The security/immobiliser lamp may remain illuminated on some models.
- Uses a 4-pin powered CAN connector and cannot use the old CANPCB cable — use the CANJST4 (101-0198) cable instead. CAN power is protected by a self-resetting 3A continuous fuse.
