cruiser54 Posted April 29, 2020 Share Posted April 29, 2020 Doesn't have to be just for an 87. 87 to 90 interchange. Link to comment Share on other sites More sharing options...

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?

omega_rugal Posted April 29, 2020 Share Posted April 29, 2020 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? Link to comment Share on other sites More sharing options...
Eagle Posted April 29, 2020 Share Posted April 29, 2020 Recent posts split. ajwyble, it makes no sense to ad a post looking for a part at the end of a four-year old discussion. Link to comment Share on other sites More sharing options...
BeaterComanche86 Posted April 29, 2020 Share Posted April 29, 2020 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 Link to comment Share on other sites More sharing options...
87MJTIM Posted April 29, 2020 Share Posted April 29, 2020 The 2.5 and 4.0 are different animals. Not compatible. BTW - what happened to the OP that re-started this thread? Link to comment Share on other sites More sharing options...
