HP Tuners GM Gen 4 Training Part 6: ECM Logic Operation

Ryan Martin on Instagram: "The new E41 ECM Upgrade Kit from @hptuners 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."
