ECM question??

Will an ECM from a '94 F150,250,350 w/4.9L E4OD
work for an '94 E250 w/4.9L E4OD?

Or in lamens terms will an any ECM work in the '94 E250 as long as the engine and trans are the same F or E series?

They are different part numbers, so something is different. My guess is, it would run, but you'd probably get a check engine light.

There are many different calibrations for the same basic powertrain combo(vehicle, axle gear ratio, region, etc) but the variances aren't big enough to notice from the drivers seat in most cases so as long as you match it to the engine and trans it'll run and drive.
