GM E46 ECM Service

Unlock the full tuning potential of your 2020-2022 Chevrolet Silverado 1500 or GMC Sierra 1500 3.0L Duramax (LM2) with ZackTuned’s exclusive E46 ECM Tuning Service. Designed for non-Global B vehicles, this service is essential to enable full custom tuning support with VCM Editor, allowing you to maximize your truck's performance and efficiency.

Industry-Exclusive Custom Tuning:

ZackTuned is proud to offer an industry-exclusive solution for upgrading the E46 ECM found in 2020-2022 Chevrolet Silverado 1500 and GMC Sierra 1500 3.0L Duramax (LM2) trucks. Our tuning service provides unique capabilities, enabling you to optimize your engine’s performance to suit your specific driving needs, whether for towing, hauling, or everyday use.

Seamless Upgrade Process:

The E46 ECM Tuning Service is a one-time, send-in option that requires you to remove your original E46 ECM and ship it to ZackTuned's headquarters. Our expert team will perform the necessary upgrades to enable tuning, ensuring your ECM is fully compatible with VCM Editor. Once serviced, your ECM will be returned, ready to be recalibrated and flashed through the OBDII port using VCM Editor.

No Reprogramming or Relearns Required:

Once your upgraded ECM is reinstalled in the original vehicle, there is no need for an IMMO relearn, crank relearn, or to perform the “Replace ECM” function. This simplifies the installation process, reduces downtime, and allows you to get back on the road faster with enhanced performance.

Important Note: For customers who require both the ECM and TCM to be unlocked, ZackTuned also offers T93 TCM Services to complement your E46 ECM tuning needs.
