I have a '95 2.5L 5spd Wrangler, and in order to get the thing started I have to put a heat gun on the ECM for ten minutes. These things are on national backorder, and I can't find one anywhere.
I've received some conflicting info on what computers from which models and years are compatible and it's driving me nuts. The part number on mine is 56028 828. I was told by a guy at a dealer that 56028 or 56027 would work, but another dealer told me that the '95 was specific. There's a 56027 811 on eBay from a Grand Cherokee which couldn't possibly be compatible, and a 56027 574 from a forum member off a '94 2.5L 5spd that screams compatible to me.
I read somewhere that if a computer had software for certain options and it found those options missing, it would adapt and disregard them. Since my car has zero options, I assumed it wouldn't be a problem. The second dealer I called said that "couldn't be farther from the truth."
What's the story with these things? I'm nervous to open the thing up and go soldering contacts willy nilly, but if the car starts when the ECM's warmed up, how bad could it be??
