Does anyone know where I can find an ecm for a 87' commanche?

Ebay is your friend here.

Doesn't have to be just for an 87.

87 to 90 interchange.

I believe the manual ECU has a more aggressive spark advance curve, then the auto. Since you can wind up a manual trans.

 

most automatics cap the rpms and cut the power during shifts, not sure if MJ´s do it, how much communication is there between the ECU and the TCU?

none

then how automatic ECUs know when to limit the rpm and when not to? you can revv up the engine in neutral and park right?

ajwyble, it makes no sense to ad a post looking for a part at the end of a four-year old discussion.

To keep this going alittle longer what’s the verdict on using a later model ECU in a 86 2.5? And does the 4.0 and 2.5 share ECU’s? Meaning there interchangeable.

Wouldn’t think so but why not ask

The 2.5 and 4.0 are different animals.  Not compatible.

 

BTW - what happened to the OP that re-started this thread?

First and only post by the OP. Asking about buying, possibly selling, stuff. Scammer?

Thanks, figured that was the case just needed a confirmation from the experts.
