Easy to install. Affordable. Reliable.

The G4X PlugIn ECUs offer the latest engine control technology and are designed to effortlessly unlock the full potential of your vehicle.

This ECU fits into the standard OEM housing. Installation is a breeze, as no modifications to the original wiring harness are required for the models listed below.

Designed for the SR20 engine. This ECU works with the 64-pin, blue connector version of the ECU.

Please check that your connector matches the header shown in the picture before purchasing.

This ECU only works with manual transmissions.

The ECU contains an integrated 7-bar MAP sensor.

Most factory features are supported.

Check the Features tab for I/O expansion options.

This ECU now features electronic throttle control (E-Throttle) as standard.

Now with 4-pin powered CAN connector (see note below).

Suitable applications:

• Nissan S13 Silvia / 180SX SR20DET (but not CA18DET)

• Nissan S14a Silvia (Facelift) SR20DET

• Nissan S15 Silvia SR20DET

*For the ECU with 76-pin header, please see the S13X PlugIn.

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 cable (code 101-0198) to connect CAN devices. This new 4-pin connector and cable not only provide 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 for 3A continuous current.
