Entering your calibration code in the on site search yields this thread which would verify your "KA' & ELF ecu is correct:

That’s the same one I sent, but it didn’t hyperlink for some reason. Looks right to me.

It wasn't active when I first read it, so I did the search & posted.

Wasn't trying to step on you post, but it did look different.

That’s not what I meant! It still isn’t active, clearly I don’t know how that works yet! Guessing OP has seen these already?

OP only says he has a ‘93 with a 7.5 engine. His profile vehicle is made up

so is he worried that you might know what kind of vehicle he owns? It’s not like we have the VIN to track him down or that Ford only made one big block truck or van(?) that year.

Sorry didn't realize I didn't fill out my profile.
So from what I'm reading that's the right ECM?

look at this thread
have you opened the PCM. Usually it's one of the 3 capicators. If you can replace those 3 capicators that should fix your PCM. I use aluminum organic polymers capicators Less likely you will have further issues. I got mine at mouser.com they are inexpensive but you have to set up an account. A bit of a pain but worth it
