Link G4X N300X Plug-In ECU, Nissan 300ZX Z32 VG30DE and VG30DETT

The Link G4X N300X is a plug-in ECU for the Z32 Nissan 300ZX, covering both the naturally aspirated VG30DE and the twin-turbo VG30DETT. It replaces the circuit board inside the factory ECU case, connects to the original loom and ships with a startup map. The onboard MAP sensor makes a MAP-based tune straightforward, which suits cars running bigger turbos or injectors.

Fits

• Nissan 300ZX (Z32) with the VG30DE
• Nissan 300ZX (Z32) with the VG30DETT
• Designed for manual-transmission cars

Before you order

• Designed for manual-transmission cars. If yours is an automatic, contact us before ordering.
• Link gives no model-year range for this unit. Compare your ECU plug with the header photo, particularly on 1996 North American (OBD-II) cars.
• Link highly recommends adding an intake air temperature sensor. The Z32 has none from the factory, so wire one through the expansion connector or in place of the fuel temperature sensor.
• The factory injector ballast resistors must stay in place.
• Electronic throttle (drive-by-wire) control is not usable out of the box; Link says this unit needs a modification first.
• 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.
• Configuration choice: Standard is the ECU as Link builds it. With E-Throttle Upgrade adds Link's factory modification (part 400-0100) so the ECU can drive an electronic throttle body. Link's HQ carries it out on a new ECU before it ships, which adds about 3 weeks. Link only modifies new ECUs, so an ECU you already own has to go through Link's tech support instead.
