Z1 engine tunes do not disable emissions control systems or the onboard diagnostic (OBD) system. The customer is responsible for ensuring the hardware they are using on their vehicle does not cause a failure to meet emissions standards.
Now you can reflash your ECU with a custom E-Tune. This reflash is dependent on you owning an Uprev cable and the ability to data log your vehicle. This listing is for one (1) E-Tune program based on your Data Log. Each E-mailed Tune will be $200.
Parameters that we will tune include:
- Up to 2 Maps on cruise control-equipped vehicles (more maps available at an additional charge, this includes alternative fuels or additional fuel types)
- Idle RPM
- Speed Limiter
- Electronic Throttle Control to achieve Wide Open Throttle at all speeds.
- Rev Limiter
- AFR Targets
- Fuel Compensation
- Ignition Timing Advance
- Cam Phasing for equipped vehicles.
- Optional: NATS (Nissan Anti-Theft System) disable is also available using the options below.
NOTE: Oversized fuel injectors above 440CC+, oversized intakes, cammed/high compression, and forced induction cars are not available for Mail-in or E-Tunes except where otherwise optioned. Custom tuning required. Nitrous tunes may be subject to additional fees.
- Optional 3'' Intake option below ONLY applies to 2007+ models with VQ35HR or VQ37VHR powertrains. Available for stock or 600cc/GTR Fuel Injectors.
- Optional 'Oversized Injector' option below ONLY applies to to 440cc+ injectors.
In-house tuning is also available, please contact the service department for details or to set up an appointment. [email protected] or 770-838-7777 ex 311
eTune Steps
