Returns/Testing:

We understand that some instances you might need an ECU to test your own machine to see if that is the problem, We don’t have a problem sending these out for testing, But if that’s what you are doing please let us know when you check out. There will be a 25% Restocking fee to cover our programming time and shipping to you.
