ECM
1985 Ford F250 Super Cab 4x4 7.5L
I posted my problem earlier and received diagnosis of failing ECM causing engine to die, cough, and backfire at about 30MPH when accelerating. Hunt for replacement ECM shows that they are not for high altitude and experts say that regular ECM will not work. But nothing is shown to be available for high altitude replacement. I bought the truck new in Denver so assume it came with the high altitude package. Does anyone actually know if the regular ECM will not replace the high altitude version. It was replaced a long time ago but can't identify anything on existing one.

Sorry I cant say if it will or will not work.
I take it no numbers on the one you have now to go by?
I also take it none in junk yards near you to grab?
I would try the one you can get as I would think it would "bolt in" ad the only thing I can see being different is the "tune", like fuel trim and timing.
Have you opened yours up to see if any of the caps have gone bad?

You can use this search engine to find a Bullnose truck in a salvage yard near you.

Why do you think that the ECM is bad?
