I was ecstatic that the ECU pros were able to repair my ECU part versus replacing it. My biggest complaint would honestly be the shipping. My order was shipped out on two day shipping, but was sent out on a Friday and FedEx apparently does not honor weekends so because the part was shipped out on Friday, I didn’t receive it until Monday. But outside of that, the service was good and if I need any future assistance in ECU repair, I would definitely recommend and return to using the ECU pros. They are knowledgeable, and thorough. They sent me a video showing the defective part as well as the repair process. Highly recommended.
