Swapping EEC's
Spent an hour hunting post's with no luck.
Question is will a EEC-IV for a 1988 5.0 liter (302) swap out with a 7.5 liter (460).
I know the firing order is the same and they seem to have the same sensors. So will it work?
For that matter does the engine care what computer is hooked up to it as long as its an EEC-IV.
I know my 460 only uses about 32 of the 60 pins on the box. Is the application just determined by the wiring harness set up?

The quantity of fuel injected per pulse will be different, so I'd be extremely reluctant to try this. Computers are calibrated for a particular engine, so they won't just simply swap back and forth, even if the pinouts match. The 302 uses 19 lb/hr injectors, while the 460 uses 24 lb/hr, so that's another thing that would throw off the fuel calculations.

Thank you for the info, I wouldent have thought of that. The reason I was asking is I have as intermittant ce light I am troubleshooting and I was thinking about swapping puters to see if that was the problem. I guess I wont try that now, at least with one from a 5.0
