I have a 2005 BMW 645Ci. Car sat for 2 years. Pulled it out the bushes. My DME was corroded so had no crank no start. I was losing my mind about why it wouldn’t start. Saw the website for ECU Pro but was scared to try them. So I called and left a message. What do you know they called right back. Had a great conversation over the phone. They are really knowledgeable about what they do. They make you feel comfortable about sending them your stuff. They keep in contact with you constantly throughout your process, which was a game winner for me. As far as time management they had me done with a few days and on the way back to me. The best part was as soon as I plugged up my repaired DME car crunk right up. These are my go to guys for DME repair and programming. Thanks ECU Pro.
