Nissan Skyline GTTLink - NGTTX Freely Programmable Control Unit

Easy to install. Affordable. Reliable.

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

This ECU fits into the factory OEM housing. Installation is simple; no modifications to the original wiring harness are required for the models listed below.

The NGTTX is designed for the RB motor with a gray connector (typically NEO).

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

This ECU only works with manual transmissions.

Most factory features are supported.

Note: This ECU does not currently output a 4WD signal, which is required for proper operation of the four-wheel drive system in 4WD Stageas and Skylines.

Note: On models with factory-equipped Traction Control (TCS), the traction control will no longer function and the TCS and skid lights will illuminate.

Check the Features tab for I/O expansion options.

This ECU must be modified before the electronic throttle can be used.
