NOTE: This ECM exchange service is completed at the owners risk, HP Tuners will not be responsible for the vehicle, its power-train or electronics, nor how the ECM is used, calibrated and its functionality. Should you experience any issues with your ECM, please contact support@hptuners.com for assistance and how to proceed.


Should you choose to exchange your ECM, as a reminder your ECM will NOT be returned to you, this service is an “exchange” service and you will receive another modified ECM in its place. Due to the factory location of the ECM in the vehicle, all ECMs will exhibit signs of weathering and wear, which is completely normal.

We exchange and modify ECMs as fast as we can, but initially, please allow at least 3 business days (plus the time to ship the ECM) per ECM that you send in for the exchange process to be completed.

NOTE: Any additional hardware ordered with this product will be shipped along with your exchange ECM. To avoid any delays should you require other hardware soon, please order that hardware separately
