In this video, we show you how to uninstall your factory ECM from your 2017-2019 Duramax as part of the ECM Mod process required to tune with the Edge EvoHT2 tuner. This brief guide will show you exactly how to complete this process.
After your ECM is removed from the vehicle, it will need to be sent into Edge Products to be modified to enable tuning. There will be documentation in your package that will explain the send-in steps.
