Description

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 V5-6 EJ20.

Note: V1.4 onwards of this Plug-in features a new 4 pin powered CAN connector and cannot use the old CANPCB cable for CAN connection. Use the CANJST4 (Code 101-0198) cable for connecting CAN devices. This new 4 pin port and cable provides 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.
