Link G4X N350X Plug-In ECU, Nissan 350Z, Infiniti G35 and Skyline V35 VQ35DE

The Link G4X N350X is a plug-in ECU for VQ35DE-powered Z33 350Z, Infiniti G35 and V35 Skyline models. It mounts in the factory location using the factory base plate, locks onto the original connector and runs the drive-by-wire throttle itself. Manual and automatic cars are both supported, and the ECU picks up gear and shifter position from the automatic over the factory CAN network.

Fits

• Nissan 350Z (Z33, Fairlady Z) with the VQ35DE, 2002-2006
• Infiniti G35 with the VQ35DE, 2003-2006
• Nissan Skyline V35 with the VQ35DE, 2003-2006
• Manual or automatic transmission; dual or quad VVT engines

Before you order

• VQ35DE only. The later VQ35HR engine is not supported.
• Link highly recommends fitting an aftermarket intake air temperature sensor, because the factory sensor sits in the MAF.
• On engines with four oxygen sensors, the heaters on the rear two sensors will not work.
• If your engine's front oxygen sensors are factory wideband type, the ECU cannot read them; Link suggests aftermarket wideband sensors with a 0-5 V controller.
• A vacuum line needs to run from the intake manifold to the ECU's MAP port.
• Compare your factory ECU plug with the header photo before ordering.
