The 350ZLink (N350X) is Link Engine Management’s G4X plug-in ECU for the Nissan 350Z (Z33) and Skyline V35 with the VQ35DE engine. Unlike most Link plug-in ECUs, the 350ZLink supports both manual and automatic transmissions. Factory drive-by-wire e-throttle and dual VVT (or quad VVT on some variants) are natively supported. An onboard MAP sensor is included. The PCB fits inside the factory ECU enclosure with no loom modifications.
The VQ35DE does not have a factory IAT sensor in a useful location. Adding an aftermarket IAT sensor near the intake is strongly recommended for accurate fuel mapping.
The 350ZLink reads wheel speeds, gear position (auto models), and shifter position over the factory CAN bus. Engine fans and AC clutch are also controlled via CAN by the Link ECU.

Frequently Asked Questions
Does the 350ZLink support automatic transmissions?
Yes — the 350ZLink is one of the few Link plug-in ECUs that supports both manual and automatic transmission. Gear position and shifter position are read from the factory CAN bus on automatic models.
Is an IAT sensor required?
The VQ35DE does not have a factory IAT sensor in a convenient location for tuning accuracy. An aftermarket IAT sensor near the throttle bodies or intake manifold is strongly recommended.
Is a base map included?
Yes. A startup base map is pre-loaded. Professional dyno tuning is required to optimise for your specific build.
