First to market product for Global B and Refresh model support
To confirm your 2022 model truck is compatible with this unit, chevk your VIN. The 12th digit in a 2022.5+ Refresh model must be a '5' or higher
Some 1500 Truck applications may still encounter DFM activation at slow speeds during deceleration when 0% throttle input is detected at the ECM
We do not control the in-cab Auto Start/Stop switch on the dash, so it will still iluminate on/off with the button being pressed as it factory, even though the system is always disabled with our module installed at the ECM.
