Really need help to get our mustang on the road!! Anyone know anywhere best in the Uk/USA to contact regarding cloning/programming a Ecu (which has matching numbers to old Ecu).
If you use Facebook look up 'Mustang Custom Services' they are based in Leyland,give Mick the owner a call and hopefully he can point you in the right direction if he is unable to help (he has a Roush supercharged Mustang)
To help a bit more, what is it you are actually trying to do? Is the original ECU fried or something or have you added mods that need to be programmed in? I assume you also mean the ECU that sits in the engine bay and not the PCM that sits in the side of the passenger footwell?
