Haltech Nexus Plug-in ECU Nissan 300ZX / Fairlady Z32 (HT-231803)
Product details
Description
A Z32 on full Nexus standalone control, straight into the factory plug.
The Haltech Nexus Plug-in ECU for the Nissan 300ZX / Fairlady Z32 plugs directly into the factory engine harness and mounts in the factory ECU location with the supplied brackets. The auxiliary connector unlocks OEM Plus functions the stock car never had, including O2 control, flex fuel, oil pressure and fuel pressure monitoring, and drive by wire throttle. On top of that, the Nexus platform brings race functionality: CO2 boost control, race timer, advanced torque management, launch control, nitrous control and 128MB of onboard data logging. Setup runs through the wizard in NSP or the Haltech Connect app on your phone, and onboard Wi-Fi handles diagnostics and tuning without a cable.
What You'll Feel
Factory start-up and idle manners with the ceiling removed. Fuel, ignition, boost and cam control become fully programmable and are tuned to your injectors, your boost setup and your fuel. Closed loop O2 control and long term learning keep the car consistent day to day, dual knock control lets the calibration run with confidence, and the onboard wideband means you see exactly what the VG30 is doing on every pull.
