ECM Service Type


NOTE: PowerLabs does NOT tune diesels. We will provide the unlock service to allow your ECM to be tuned, but after that, you're on your own.

The L5P ECM Service from HP Tuners gives you the power to tune your 2017+ Chevrolet Silverado and GMC Sierra 2500/3500 6.6L Duramax. Take advantage of any of our three available options to calibrate, log, and scan via your vehicle’s OBDII port. With any choice, you receive an E41 ECM that is compatible with the MPVI2/2+ and VCM Suite.

ECMs with broken tabs or connectors WILL NOT be accepted for Upgrades and Exchanges.

Please allow 2-3 week lead time for processing

Upgrade Service

Upgrade your existing E41 ECM without having to trade it in or purchase a new one. This option offers a direct servicing of your current ECM. You send it in, we get it ready for tuning, and send it back. NOTE: Requires core.

L5P ECM Upgrade Service: $649.99
ECM (E41) License: 8 Universal Credits

Advantages of the L5P ECM Unlock Service:

  • No need for an IMMO relearn*

Please allow three to four days for service plus shipping time. *As long as all of these items were completed before sending in your ECM.

Exchange Service

Exchange your original ECM for one that is ready for tuning. Upon receipt of your current ECM, we’ll ship a professionally upgraded module that’s compatible with your vehicle. NOTE: Requires core (can be new/blank core).

Notes on L5P Services

  1. Your Purchased, Exchanged, or Upgraded E41 ECM can only be tuned via the OBDII port with an MPVI2/2+ (updated with the latest firmware), VCM Suite (version 4.3+), and an internet connection.
  2. No other tuning or calibration tools can be used with the ECM (including dealer reflash tools).
  3. VCM Scanner, Dealer Diagnostic, and other diagnostic tools will continue to function normally.
  4. VCM Suite (version 4.3+) can be used to return to the stock calibration and/or update to the latest stock calibration.
  5. If participating in the ECM Exchange, the Vehicle Anti-Theft System relearn (by a dealer tool) is required once the new ECM is installed.
  6. If you are participating in the ECM Exchange service, your ECM must be an original, functional module in an unopened and unmodified condition.
  7. Both the L5P ECM Exchange and L5P Upgrade Service take about three to four business days to complete (not including shipping times).
  8. HP Tuners reserves the right to refuse any ECM exchange.
