“Found their label on a ECU in a car I bought. Figured I would give them a try and very glad I did. Could have charged me $500 for what I thought was already a bad ECU. Instead told me the problem was elsewhere.”

“Quick turnaround and I love that they put the parts on a known-good vehicle to show it running and saved me the cost of the dealership saying, "It might be the DME, that will cost you 4k." The test was under an hour of diagnosis cost at the dealership. After I got the DME back after a successful test, I checked the ground, and I was only grounding 9v from the hot plug to the oil cooler. Turned out to be a $40 ground strap on my 2011 335i X-Drive. Took like 30 minutes to replace and it fixed the no crank no start issue. Above all: CHECK YOUR GROUND STRAP!!!!!!!!!!!!!!!!”

“Replacement ECU for 2007 CLS works great. Turnaround time was under 2 wks to include trasit time and testing of old ECU. Very satisfied and for better that the $5k price quoted by Benz dealer. There are a number of ECU repair/replacement firms out there. ECU Pro seemed very professional and efficient. Thanks”

“I found the website by doing a simple Google search. I contacted them for support and they explained the process to me thoroughly. I especially like that they sent me a video verifying that the part worked in a vehicle.”

“My car stopped starting. I removed my DME and CAS module and send it to ECU PRO. Around seven days later I received my modules. I plugged them in the car started right up. Thanks for fixing my modules.”
