SKU: 238-4000

Note: Check Engine light remains illuminated for some vehicles due to a CAN bus change. It appears everything else works correctly, but it has not been thoroughly tested in all regions. We are aiming to be able to fully support these models in the future.

Easy to install. Affordable. Reliable.  

G4X PlugIn ECUs offer the latest in engine management technology, designed to easily maximize the potential from your car. This ECU fits inside the factory OEM enclosure. Installation is a breeze, with no alteration of the factory wiring loom required for the models listed below. Designed for the WRX V11 EJ20/EJ25 Turbo (GR/GV/GH/GE chassis, MY2007-2011, Denso ECU from factory). All factory functions including DCCD, hill start assist, SI drive, cruise control, cam control & ABS supported. 

Note: This Plug-in features a new 4 pin powered CAN connector and cannot use the old CANPCB cable for CAN connection.  Use the CANJST4 (Link PN 101-0198) cable for connecting CAN devices.  This new 4 pin port and cable provide not only the CAN connection, but also a protected 12V power supply and ground for powering the CAN devices. The power supply is protected by a self-resetting fuse rated at 3A continuous.
