Important Notes:
HP Tuners supports 2020-2022 Chevrolet Silverado 1500/GMC Sierra 1500 3.0L Duramax (LM2) trucks that are non-Global B. This includes “facelift” trucks as they are Global-B and contain a different controller.
ECMs with broken tabs or connectors WILL NOT be accepted for Upgrades.
This service only upgrades your original ECM for tuning, it does not reprogram your ECM for a different VIN. If you intend to send HP Tuners a spare E46 ECM, it will be returned to you with the same programming as it was received and may not operate in your GM vehicle without additional programming by a GM dealer.
Your E46 ECM core must be fully functional with no physical or internal damage.
No other tuning or calibration tools can be used with the E46 ECM (not including dealer reflash tools).
VCM Scanner, Dealer Diagnostic, and other diagnostic tools will continue to function normally.
The latest version of VCM Suite can be used to return to the stock calibration and/or update to the latest stock calibration.
The E46 ECM upgrade service takes about 1 to 3 business days to complete (not including shipping times).
HP Tuners’ E46 ECM support does not cover the Chevrolet Suburban LM2 at this time.

Disclaimers:
These PCM services are completed at the owner’s risk. HP Tuners will not be responsible for the vehicle, its powertrain, or electronics, nor how the PCM is used, calibrated, and its functionality.
Due to the factory location of the PCM in the vehicle, all PCMs will exhibit signs of weathering and wear, which is completely normal.
