Rich: Is the 94 and after self learning? I have read about the differences from PCM to PCM but didn't know that the 92 didn't do that function. I believe you can have the 94 and later ones reflashed but don't quote me on that. Not being able to reflash the 92 PCM was a disappointment. The advent of the MegaSquirt PiMP at least gives me hope again. It's sort of the light at the end of the tunnel. WEK.
