Hey everyone, So after a few long days of research and phone calls, my tuner is locked out and too old for the company to fix as they no longer support this device. My ECM is now messed up and the car will not start. I now have to have my ECM reflashed or replaced. I have done some research and based on some information I have come across, 96-97 do not need to be reflash because they do not use a chip key and the only PATS is a light on the dash that is not linked or affect the ECM. I have tried calling a Ford dealer to see if they can confirm this, but they won't say. I have also tried decoding the ECM part number to also see if it requires it to be reflashed, but also had no luck there. Can anyone help me? All I want to know is if I install a used ECM from the same make, model, year and engine size....... if it needs to be reflashed or is it plug and play?
