Trying to put 2010 1.8 Petrol back on road, when i got the car it was missing the ECU (PCM) as had been damaged in crash i got a second-hand replacement 7M51-12A650-VC but are now lost have tried reprogramming using IDS and ELMconfig but filmware just wont write to the PCM in reality its just the VIN. Im think now is teh PCM the right Ford arent that helpful happy to sell me a new one but cant or wont tell me the one that was installed on the car originally. Are all the 7M51-12A650 ECU the same hardware with the VC being the filmware, If so should i be able to reflash the ECU with the lastest filmware for the car.
