Great service and turn time! Plugged in the fixed ECU in on my daughters 2012 Mini Cooper and crossed my fingers! Boom! All is good. So glad I found this! If you have limited mechanical skills you can do this yourself as I did. Stupid trim removal is the hardest part. Lol Really tho. Saved me $1400 at least. I sent into ECU pro for test which was $99. Got a notice it could be fixed for $250. Thought awesome only $340. But when I went to pay that they gave me credit for the $99 and only charged another $150. All together $250! Totally could have got me for the $350 and would have been fine with that. Stand up company for sure!
