Upgrade Your E41 ECM Right in the Garage/Shop
The new E41 ECM Upgrade Kit gives DIY enthusiasts and professional tuners a convenient option to perform the ECM upgrade on their 2017+ Chevy Silverado/GMC Sierra 6.6L Duramax in their own garage/shop. The best part? There’s no need to remove the ECM from the truck. This means there’s no risk of breaking tabs during the removal or reinstallation process. This kit also doesn’t require any reprogramming or relearns.
- No IMMO relearn
- No crank relearn
- No need to perform “Replace ECM” function
From start to finish, you can upgrade your E41 ECM in roughly 20 minutes—all you need 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. Once the ECM is upgraded, experience the industry’s most comprehensive diagnostics and tuning package using VCM Suite with full scan, data log, read, edit, and write capabilities. Plus, experience the quickest write times in the industry—approximately 6 minutes!
