“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.”

“Thank you so much. It was a bad battery that fragged the FRM. All is good 👍 now. Just need to figure out the massive oil leak that started this entire process. You are the best...”

“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.”

“Company is extremely poor at communication. I shipped my unit for repair. It was simply shipped back, unserviced, not information as regards why. Had to make calls for more details. I thought notes could've accompanied the return shipment. ECU pro can do better than that.”
