RE: 1994 ECM PCM INSTALL??
The ECM is a GM reman ECM. I replaced it due to an injecter not fireing. Now the motor runs good (with the new ECM) but the trans shifts hard. I put the stock ECM in and #6 injecter will not fire but the trans shifts great
thanks

so you think it is a bad reman ECM?

Still maybe bad ecm, after all they are rebuilt. Fuel injector driver will not be in the same part of ecm as trans controls.

I got a 2ed ECM from the junkyard they did an interchange and it is out of a 95 olds aurora. I put my prom in it from the stock ecm started the car. The car ran but has "no pcm data" I checked the prom it was in good.
So my stock ecm will not fire injector #6 but everthing else works
The gm reman ecm will fire injector #6 and the car runs great but the trans shifts very hard
The interchange ecm (95 aurora) the car just runs in defalt mode and has "no pcm data"
any idea's?
