Zapped my computer on my 1991 LTD and searched the junkyard for matching numbers (E8SF-VA) but could not find the right wreck. Another junkyard had one when I called and when I picked it up, they told me that E8SF-AEA is a dealer replacement for my original.
I wouldn't even be asking except the engine still isn't running right with the replacement. It's possbile I zapped even more (will run diagnostic on new ECU to determine) but thought someone may know about ECU compatibility. Will E8SF-AEA work in place of E8SF-VA?
Any guidance is appreciated,
