Z1's Carb Legal Nissan Frontier Performance Tuning Package provides the best tuning solution for your VQ38-powered truck outside of our in-house services. The Level 1 Tune (base) requires no dyno tuning and is expertly pre-calibrated to suit your vehicle and meet California's CARB requirements. This tune is identical to the Level 1 Tune in our Performance Tuning Package and offers the same performance advantages, however, it meets all CARB requirements and has been tested to be in compliance with CARB standards.
Carb Legal EO: D-849-3
Included with the purchase of the Level 1 Tune is an EcuTek OBDII bluetooth performance analyzer and adapter, used to install the provided ROM file onto your stock ECU through EcuTek's ECU Connect App. EcuTek allows full bluetooth vehicle integration with their ECU Connect app for mobile devices. The ECU Connect software gives you the ability to switch maps, read and reset diagnostic trouble codes (DTC), and gives you access to a huge number of diagnostic parameters. Through their bluetooth app you have access to data logging of hundreds of parameters, including detailed ignition and knock control, fuel injector timing, intake air temperature, and more!
*Please make sure your phone is compatible with the EcuTek connect app before ordering. When setting up your account through EcuTek Connect, please be sure to use the SAME EMAIL that you use for your Z1 account. Failure to do this may result in extended processing time.
