With any choice, you receive an E41 ECM that is compatible with the MPVI2 and VCM Suite.

NEW PURCHASE
Purchase a new ECM from HP Tuners and keep your original. Ideal for enthusiasts who want their vehicles up and running as quickly as possible. NOTE: No core needed.

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.

Advantages of the L5P ECM Unlock Service:

• No need for an IMMO relearn*
• No crank relearn*
• No need to perform the Replace ECM Function in VCM Scanner*

*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.

Notes on L5P Service
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.
No other tuning or calibration tools can be used with the ECM (including dealer reflash tools).
VCM Scanner, Dealer Diagnostic, and other diagnostic tools will continue to function normally.
VCM Suite (version 4.3+) can be used to return to the stock calibration and/or update to the latest stock calibration.
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.
If you are participating in the ECM exchange service, your ECM must be the original, functional module in its unopened and unmodified condition.
Both the L5P ECM Exchange and L5P Upgrade Service take about three to four business days to complete (not including shipping times). HP Tuners reserves the right to refuse any ECM exchange.
