“This company was incredible and everything they said it would be, I sent My switch with a key and they diagnosed it and repaired it in less than a week. THe price was upfront and it was shipped back within a day after payment. I would give ten stars*******”

“Excellent and fast service. My FRM came back in working condition and with some helpful reinstall instructions. I mailed it to ECU on a Friday and got it back the following Tuesday.”

“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.”

“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!”

“This process has been seamless with the transactions, information and support. I have one lingering challenge that has not been resolved yet, but I’m hoping it will be with my FRM for my 2012 Mini Cooper S.”

“Rating could have been higher if the video on diagnostic including dialogue/expanation on what's going with the video, like in u-tube.”

“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 ⭐️⭐️⭐️⭐️⭐️”

“Good communication, honest work and timly service. I started with a company in Florida and they were not good and could not get the job done. I came into the expirence with doubt and they came through. My personal thoughts are they are very good.”
