The HP Tuners GM E41 ECM Upgrade Kit offers a convenient option for DIY enthusiasts and professional tuners to perform the ECM upgrade on their 2017+ Chevy Silverado/GMC Sierra 6.6L Duramax in their garage or shop.
There is no need to remove the ECM from the truck, eliminating the risk of breaking tabs during the reinstallation or removal process.
You can upgrade your E41 ECM in roughly 20 minutes from start to finish—all that is needed is this upgrade kit, your MPVI2+ (with Pro Feature Set) or MPVI3 device (with its supplied USB A to C cable), and a VCM Suite-compliant computer with the latest version of VCM Suite BETA.
This kit does not require any reprogramming or relearns, including IMMO relearn, crank relearn, or the “Replace ECM” function.
After upgrading the ECM, utilize the industry’s most comprehensive diagnostics and tuning package with VCM Suite, which includes full scan, data log, read, edit, and write capabilities.
Additionally, experience the quickest write times in the industry—approximately 6 minutes.
