FAQ

1. MPVI Device:
   The MPVI device is necessary for reading and flashing tune files, as well as logging data from your vehicle. For more information, visit MPVI3.
2. Wideband Sensor:
   A wideband sensor is required for forced induction vehicles and optional for most naturally aspirated vehicles. It is essential for accurately measuring the air-fuel ratio (AFR) in exhaust gases under various conditions. Unlike narrowband sensors (commonly used in most GM vehicles), which can only indicate whether the AFR is richer or leaner than the ideal stoichiometric ratio, a wideband sensor provides more precise AFR readings. This is especially important in high-performance applications. A recommended option is the AEM Electronics Wideband Sensor.
3. Laptop:
   A laptop with Windows 10 or a newer operating system is required for the tuning process.
