If you are not installing the device on a 2011 or newer Duramax, then please go to "Change Vehicles" at the top of the main menu, and select the correct vehicle application.
If the vehicle is a 2011 or newer Duramax, make sure the device is up to date with the latest version. Click here for instructions on updating.
If the device is up to date, you will need to contact our tech support with the device powered up and a PC with internet access. We may need to have our engineering department add support for the new ECM part number.
