“The ECU check service provided by ECU Pro was invaluable in diagnosing the problem. Although the ECU turned out to be okay, which allowed me to move on to what's apparently the only thing left. Also, I found the provided video, which showed my ECU in action (working) and was confidence-inspiring. The only ding in the process was this: I had contacted ECU to request that they ensure my components when they shipped them to me, as it would cost me at least $1500 to replace them with reconditioned parts. I told them I was happy to pay the additional cost of the insurance. They promised that they would do that, but did not. So, I held my breath for three days while it was being shipped back to me, and I watched my porch like a hawk on the day of delivery. Fortunately, it was delivered.”

“The ECU Pro had pretty good turnaround time and I did eventually get help, but the process had a few bumps along the way. Overall not a bad experience, just wish some parts of communication and handling were a little smoother.”

“They were honest to begin with when they explained the initial assessment of my EIS. I chose to go with a replacement anyway. The one they had on hand did not pass final inspection and it did take almost an extra couple of weeks for them to get a replacement reprogrammed for me but all in all they were pretty quick with reaching out and good about staying in contact. So far my replacement is working as intended. I would do business with this company again no problem if I was in need of their services again.”

“Great overall service for my CAS repair/replacement. Ive used their services twice before for my FRM aswell. Had a small issue with one of my keys, which could have been communicated better. Otherwise great support and worksmanship.”

“Thank you ECU Pro. The process was simple, affordable, and quick. The email updates were detailed and often to keep me informed where you were in the process. I installed the repaired ECU and the previous issues were gone.”

“If you're experiencing DME or CAS issues with your BMW, or if you're facing problems with the EIS in your Mercedes-Benz, ECU Pro is the way to go. I've relied on them for the past couple of years and trust their repair work completely.”

“My ECU for my 2013 Mercedes C250 Coupe has been working perfectly after sending it to The ECU Pro to get tested.”

“ECU Pro provided excellent service. I sent in my CAS, DME, and key for testing/repair because my MINI had a security mismatch issue. They confirmed the CAS and DME security codes did not match, re-matched them, and even tested my equipment in their vehicle to verify it started properly. Communication was clear, the turnaround was professional, and they provided a video showing the repair working. Great experience overall and I would definitely recommend ECU Pro for CAS/DME/key issues.”

“First time ordering from ECU Pro. They are very professional. They kept me in the loop about everything that needed to be done. I sent my DME for repair and ended up needing a replacement. The Technician helped me with all questions and suggestions as well. The DME works great!! Very Happy with the replacement!!”
