I've got a remanufactured EECIV that I want to try and identify. How do I go about it? The cover has no information, so I took it apart and found the following:

EEC-IV EFI TC5
E6ZF-14A608-BA PWB-391

It's got a 7.5Mhz crystal, and the Toshiba 6127 processor.

Ideas?

Now thats a tough one. Someone here who works at a Ford dealer should be able to run the part number and see what it brings up.

I looked but couldn't find anything on an EEC Reference PDF Document I have. I just browsed through it, maybe you might have better luck than I did.

I've looked through that document, and haven't run across anything yet.

It came out of my supposed 85.5 SVO.

The more I look through the car, the more history I find...

E6ZF-14A608-BA means that this is a 1986 or later processor (E6=1986) for a mustang with one major revision (BA). I think that you have a brain for either a non turbo 2.3, 3.8 V6, or a speed density 5.0 from 1986. It could possibly be a speed density brain from a 1987 or 1988 mustang 5.0.

If it were the correct processor for a 1985.5 or 1986 SVO the calibration code would be PE instead of TC5. Additionally the part number would have looked something like E5ZF-######-## as the PE processor made its debut on the 1985.5 model SVO.

When I go home tonight, I'll see if I wrote down the part numbers and stuff on the computer in my 85.5 and post them.
