98 ecu in a 95 engine

[Chris_97]

I'm wanting to do a manual swap with a 98 parts truck into my 97 auto with a 95 engine in it. Both are the 4.0 and was told because the fuel pressures are different for the two engines I might need a different one. I've looked everywhere online and can't find anything on it. Any help is appreciated.

How did you put the '95 engine in you're '97? The logical way would have been to just use the block/heads.

If that's what you did, then for all intents and purposes you still have a '97.

Yes..my truck has a 98 2.5 that used the higher fuel pressure but the previous owner used the 96 fuel injection, intake and exhaust and every thing just bolted up...running on the lower fuel pressure of 30-40 psi and was working just fine for five years...
