“So far so good working good”

Helpful Report

“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.”

I would highly recommend there services!!!!”

“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!!”

“Amazing expirence and they fixed all my issues. Would reccomend and use them, they are amazing. I have been chasing down strange electrical issues and I was on my wits end. My 2008 535i is mechanically sound, but I was ready to get rid of it because I could not track down the issue. I found a review on Youtube of someone with similar issues, where they sent the ECU and CAS to ECU Pro and the issues were fixed. They recieved my ECU and CAS on a Wednesday, sent me a video of the everything working on a donor car the following Tuesday, they reported that the CAS had an issue and they were able to repair it. They shipped it back to me, and I was able to put them back into my car on Thursday. ALL MY ISSUES ARE FIXED! Thank you so much for fixing my car! You guys are amazing!”

“I had a great experience with ECU Pro from start to finish. I trusted them with my car’s computer issues, and they absolutely met my expectations. The turnaround time was fast, communication was great, and they really seemed knowledgeable about what they were doing. Before sending my ECU in, my car was doing several weird things and acting up intermittently. Ever since getting everything back from ECU Pro, those issues have completely gone away and the car has been running exactly like it should. It’s hard to find companies you can trust with something this important, but ECU Pro definitely earned my confidence. Highly recommend them to anyone needing ECU repair or programming work done! 5Stars ⭐️⭐️⭐️⭐️⭐️”
