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 theSR20 engine. This ECU will work with the 64 pin, blue header plug ECU version.

• Please check your connector matches the header in the listed photo before purchasing.  
• This ECU works for manual transmissions only.  
• ECU includes an onboard 7 bar MAP sensor. 
• Most factory features are supported. 
• Check the features tab for I/O expansion options.
  • This ECU now includes E-Throttle as standard.
  • Now with 4 pin powered CAN connector (See note below).

Suitable Applications: S13 Silvia / 180SX SR20DET (but not CA18DET)
S14a Silvia (facelift) SR20DET
S15 Silvia SR20DET
S15 Silvia SR20DE
RNN14 Pulsar GTI-R SR20DET
N15 Pulsar SR16VE
N14 Distributed
*For the 76 pin header ECU, have a look at the S13X PlugIn listing.
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 (Code 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.
