Visconti Tuning Nissan Z (2025+) Gateway Bypass Harness

Visconti Tuning Nissan Z (2025+) Gateway Bypass Harness

The Visconti Tuning Nissan Z Gateway Bypass Harness allows ECU programming on secured gateway-equipped Nissan Z (2025+) vehicles through a secondary OBD2 port without removing the ECU from the vehicle.

Nissan Z vehicles equipped with an updated gateway module include additional security that prevents ECU programming over the factory OBD port. The Visconti Tuning Z Gateway Bypass Harness allows ECU programming without removing the ECU from the vehicle or performing a bench flash.

How it works:
This plug-and-play harness bypasses the gateway module, allowing EcuTek RaceROM to be flashed directly using ProECU or ECU Connect via the included secondary OBD2 port. Installation is straightforward and requires no cutting, splicing, or permanent modifications.

Racebox Return Program:
After you have completed programming your vehicle, the harness can be shipped back to Racebox. Once received, we will refund the ENTIRE cost of the harness minus shipping costs.
