No, im talking about the ECM, not to be confused with EFI. I'm talking about the computer.

That truck has an EEC module to control spark timing... essentially just an electronic ignition system, it was called an engine control system but it didn't have anything to do with fueling. There are no plug-in upgrades for this, if you want something newer you could substitute a complete modern electronic ignition system(electronic box + distributor + wiring harness) but there is no performance to be gained and the new stuff may not be as reliable.... Ford electronics was built to military standards while these days everything is cheap chinese junk.

Yeah there's nothing to be gained. The EEC unit barely does anything at all. Advance the timing a bit like you would on any old vehicle and you'd gain more performance.
That being said, what about the 86 unit for a 302? That does control fueling. Any upgrades to do there? (Without swapping to a whole new system)

5.0 had a EEC version also. The 5.8 had a EEC version, but then you have the 5.8 HO which did not have EEC. You have 50 state trucks, California certified trucks, trucks made in Canada and then you have the heavier GVWR trucks. All can have different emissions and engine management, but have the same basic mechanical engine underneath. While the smaller engines had many different versions, the 460 stayed with duraspark and a 4 barrel carb till it came out with fuel injection later on in the late 80's.
