– To tune your L5P ECM you require 8 Universal Credits, an MPVI2 with the latest firmware, the latest version of VCM Suite 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.

A reminder that your ECM will not be returned to you, this service is an “exchange” and you will receive another modified ECM in its place. There is no outright purchase option available at this time.
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.
