  1. Your Purchased, Exchanged, or Upgraded E41 ECM can only be tuned via the OBDII port with an MPVI2 (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 three to four business days to complete (not including shipping times).
  8. HP Tuners reserves the right to refuse any ECM exchange.

**All exchange and upgraded ECMS are required to be sent in so that we can inspect them and unlock them. You will not be credited back for an ECMS with damaged locks, tabs or broken pins**


**Exchanged ECMS are turned around in 1-3 business days, but can take up to a week for initial turn around. Please plan accordingly**
