I'd love to read the PDF. I didn't see it attached to the post. Is it in another post of yours? If not, could you provide a link? I think I'm good at editing tables in TunerPro, but where I stumble is which table to edit. For example, there for where does D0901 change to D0903 or D0904. The engine/transmission is in an 1991 S10, so I know there is not a switch hooked up for performance mode (D0902). Is it safe to assume that the PCM will never switch to performance mode if there is no switch connected to the PCM pin? Thanks again for helping me with such basic questions.
