I was told the pinouts for the 94 and 97 powerstroke PCM's are different. I thought they were interchangeable. Anyone know for sure?

I would like to put a 97 computer in my 94. It is a lot more recent programming and shouldn't hurt I would think. I'm mostly wanting to do it because I am sick and tired of not being able to use my scanner in the OBD2 port on the 94. I can on the 97. Both pcm's I have now are 49 staters. 94 is a 5 speed, 97 is an E4OD.

 

My PCM is a junk yard special, but I dont recal if it said 94 on it or 96.
I think it said 96.

 

You can install a 97 PCM in a 94 & 1/2 up PSD.

 

as stated you can install the '97 PCM in the '94, you will now have a 225HP '94.5 PSD, instead of a 215HP.

One thing for anyone else reading to watch out for is you can put an Auto trans PCM in a 5 speed truck but you CAN NOT put a 5 speed PCM in an Auto. apparently they dont have the logic for the trans.

the great J Tipton told me that years ago.

I have also heard that the 97 Cali model PCM is different than the 49er's.

 

'97 cali trucks had Split Shot Injectors so yes it is different.

hello I have a 1994 idit that im putting a powerstroke in I have a donor truck but someone robbed the pcm out of the stroker I was wondering if the idi one would work there are both autos and if not where could I get one?

A 94 IDI did not have a PCM. The auto tranny might have had a brain box, but not a PCM that controlled the engine. You will have to find a PCM for a 95-97 truck that had an auto tranny in it, as all 94.5 trucks with the powerstroke were equipped with the ZF5 manual trannys.
