I have a 2004 f250 6 liter turbo. After chasing wires and checking power and fuses, and then taking it to my mechanic. It looks like the PCM is dead. My question is about model numbers of PCM units. the ending on mine in ATH. I see there are 4 or 5 different ones for that year. I know they each are a little different, but can they be flashed to the right software ?? My Unit is a 4U7A-12A650-ATH. there are a couple that are still DSH7 series but with different last letters. Will one of these work?? EGH, EGF, EGE etc??

Thanks For any input
