Engine management computers-vehicle specific?
Might be kind of an odd question, but....
I'm doing some work on a friends 89 F-150 that's equipped
pretty much like my Bronco (5.8 liter, C-6, etc).
Sometime in the past, he was having driveability problems and swapped out the computer with another one from a salvage yard - he said it was from a truck equpped the same has his.
The question is this - are the computers specific to an individual vehicle, to a group of vehicles (similarly equipped), or can his
performance be improved by switching to a different computer-
say something from a Lightning? And if they are vehicle specific,
what/where are the indicators for the vehicle?
I haven't got a clue what to tell this guy....

the computers are all the same for most vehicles that have the same tranny, motor, and other accesories like ac and such.
a lightning computer would work but i believe the firing order is different and the cam for the lightning is also different which could be good or bad. here is a great website with so much efi info on all that stuff. the guy that admins it knows his stuff
