“The ECU in my CLS550 had a problem with the start circuit. It took as many as 10 attempts to get the car started. The ECU Pro was able to identify the bad solder joints and fix them. Works great now! Thanks for the quick work and for saving me the $3000+ that Mercedes wanted for a replacement ECU. BC”

“The time frame from shipping to then receiving the part back was within 7 business days. I sent my ecu in for examining thinking I would have to replace it, they fixed it for a quarter of the price a brand new one would be from the dealership. I got the part back, plugged it in and my car works perfectly with no check engine light!”

“I sent my ecm to PA by USPS 3 day priority mail, rom FL they rec'd it in 3 days over the weekend. They did not look at my ECM until Tuesday. They stated they got 50 ecm's in the mail on Monday. At that time I stated to replace it. It took ECUPRO until Thursday to ship out my ecm. They state on their website and the invoice it is Fedex 2 day Express. I did not get my ecm until late Tuesday, 6 days later. I took my car for a short ride on Wed. about 10 miles total, it seemed to work fine. The real proof will be tonight when I hve to drive 35 miles for groceries and back home. I am praying it does not stall, like it had been.”

“Reviewing prematurely just to get the warranty extension. Not sure if I’m going to need it yet or not. Received my ECU back and the cylinder #3 misfire was fixed but immediately after installation I have P0001 code for fuel system circuit open that I didn’t have before so I now have to take my car to a mechanic to get the fuel system tested before I can send my ECU back in for warranty repair. I will revise my review depending on the final outcome.”
