Link G4X NGTRX Plug-In ECU Bundle, Nissan Blue-Header RB: ECU, XS Loom, CAN Lambda and CANJST4

This bundle pairs the Link G4X NGTRX plug-in ECU (214-4100) for blue-header Nissan RB engines with three parts most builds add next: an XS expansion loom, a CAN Lambda wideband kit with a Bosch LSU4.9 sensor, and the CANJST4 cable that connects and powers it. Fitment is the same as the NGTRX on its own, so check your header colour and engine against the list below.

Fits

• Nissan Skyline GT-R R32, R33 and R34 with the RB26DETT, and the Autech 260RS Stagea
• RB20DE: R32 and R33 Skyline, A31 Cefiro
• RB20DET: R32 Skyline (including 4WD), A31 Cefiro, C33 Laurel; injectors 4 and 6 must be swapped
• RB25DE: R32 and R33 Skyline, C33 and C34 Laurel, A31 Cefiro
• RB25DET: R33 Skyline (including 4WD), C34 Laurel
• RB30DE, RB30DET and RB30DETT builds with non-NEO heads and blue-plug looms
• Designed for manual-transmission cars

Before you order

• Blue ECU header only. Cars with the grey NEO header, such as the R34 GT-T, need the NGTTX (215-4000) instead.
• Link lists Japanese-market vehicles only; in North America this means imported cars.
• Designed for manual-transmission cars. If yours is an automatic, contact us before ordering.
• Electronic throttle (drive-by-wire) control needs an expansion connector before it can be used.
• One CAN Lambda module runs one wideband sensor; this bundle includes one module and one Bosch LSU4.9 sensor.
• The CAN Lambda comes with a Deutsch 4-way connector kit for terminating its wiring.
• Link notes that Bosch's warranty excludes aftermarket use, so the LSU4.9 sensor carries no warranty.
• Known issue noted by Link: the factory optical crank angle sensor can cause trigger errors at high rpm or with aftermarket cams and valve springs; an aftermarket trigger disc or a crank trigger is the usual cure.

Highlights

• NGTRX plug-in ECU: onboard MAP sensor, two CAN buses with powered 4-pin connectors, startup map, factory case and loom
• XS Expansion Loom: 2.5 m of 22 AWG wire that plugs into the ECU expansion connector for extra sensors, switches and controls
• CAN Lambda kit: Link's CAN wideband module with a genuine Bosch LSU4.9 sensor, fully digital over CAN, no free-air calibration, plus an O2 bung and plug
• CANJST4 cable: 300 mm lead from the ECU's 4-pin CAN socket that carries CAN and a protected 12 V supply for devices drawing under 3 A
• G4X core features: flex fuel, open and closed-loop boost control, dual closed-loop lambda, VVT control, a built-in trigger oscilloscope and 512 MB of onboard logging
• Motorsport functions: launch control, anti-lag, traction control, nitrous control, cruise control, gear shift and paddle shift control
• USB tuning cable in the box; PCLink tuning software is a free download from Link
