  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 purchasing a new ECM or 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 the original, functional module in its unopened and unmodified condition.
  7. Both the L5P ECM Exchange and L5P Upgrade Service take about four to five weeks to complete (not including shipping times).
  8. HP Tuners reserves the right to refuse any ECM exchange.

When you select the L5P ECM Exchange Service, you will need to:

  • Provide your VIN.
  • Indicate the vehicle year, make, and model.
  • Perform the Replace ECM Function in VCM Scanner for the stock ECM.
  • Include the following information with your shipment on a separate sheet of paper:
  • Customer name
  • Customer address
  • Customer contact information (email and phone)
  • L5P ECM Exchange Service order #
  • If you are opting for a TCM (T87a) Service, please indicate so next to the order number
  • Specify whether the ECM is the original from the vehicle or a new/spare ECM.
  • Indicate your preferred UPS shipping method (the default shipping is UPS ground; however, expedited shipping is available via the checkout process).

Missing information will delay the ECM exchange process. Please ensure you follow the instructions above and review the installation instructions.
