Thread: Canned Tuned PCM'S

Are they interchangeable between models? Does anyone know if a 1.0 tuned PCM from a 98 GTP, can be installed in a 98 GS.....or a 98 Olds LSS Supercharged?

the only problem with tranfering it is that the final drive ratio on the transmissions are different.

I tried to run a Buick pcm in my GTP and it wouldnt crank. Stick with 98-02 years, and stay within the same make/model.
