“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.”

“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.”
