2017 - 2018 L5P GM E41 ECM Upgrade Kit | L5P Unlock Cable

**In stock and ready to ship** HP Tuners, the leading automotive diagnostics and calibration solution, has released a new GM E41 ECM Upgrade Kit allowing professional tuners to upgrade E41 ECMs found in 2017+ Chevrolet Silverado and GMC Sierra 2500/3500 6.6L Duramax trucks (L5P and L5D applications) in the convenience of their own shops. By design, this kit eliminates the need to remove the original E41 ECM from the vehicle and thus potentially breaking ECM tabs. Now, professionals can perform the upgrade in the vehicle in roughly 20 minutes. This new kit works in conjunction with the new MPVI3 interface to unlock your E41 ECM without having to remove it from the vehicle—this is key for tuning shops that can’t afford downtime. Custom calibrations, data logging, and scanning are now fully functional in just a few quick and simple steps—no need for Immobilizer Relearn, Crank Relearn, or Replace ECM Function. Shops will also experience the fastest E41 unlock and flash times in the industryؙ—7 minutes for unlock and 6 minutes for write time! Provided with this do-it-yourself kit are three main components: the HPTNet Cable, the Upgrade cable, and the Upgrade box. During the upgrade process, users will also need an MPVI2+ (with Pro Feature Set upgrade) or an MPVI3 interface, the latest version of VCM Suite BETA, and (8) Universal Credits to license the vehicle.
