E90 / E93 ECM Purchase

• E90/E93 ECM License for tuning: (6) Universal Credits (sold separately)
• Users must follow these installation instructions to properly install the new ECM.

E90 / E93 ECM Upgrade

Upgrade your original E90 or E93 ECM by sending it to HP Tuners. We will upgrade your original ECM so it’s ready to accept tunes, and then we’ll send it back. After upgrading, you’ll have full access to calibrate, log, and scan via the OBDII port. This option takes at least 3 business days to complete (not including shipping times).

• E90/E93 ECM Upgrade Service: $299.99
• E90/E93 ECM License for tuning: (6) Universal Credits (sold separately).
• No relearns or reprogramming is required as long as the ECM returns to the same vehicle it came from.

Note: The E90 ECM Exchange Service is no longer available, effective 3/16/2023. Please select E90 ECM Upgrade Service if you wish to send in an ECM. For any additional questions, please contact support@hptuners.com.

Note: Universal Credits for licensing are not included in the cost of any ECM/PCM/TCM service. Credits must be purchased separately.

Note: HP Tuners also offers support for the T43 TCM found in many E93 ECM-equipped GM vehicles. This T43 TCM does not require an unlock service and is free to license.
