    Memory address for D0906-8 tables in OS12587603

    I am using TunerPro and was reading over at https://forum.efilive.com/showthread...e-shift-points how to adjust the shift points for my dad's transmission (4L60E). They discuss tables D0906-8. I have the XDF for 12587603 but it only has D0901 through D0904. Does anyone know the memory addresses for D0906, D0907 and D0908, as well as any other information (I assume 2 byte cells and the same X and Y parameters as D0901-3? I can add it to the XDF if someone can give me the info.

    You are looking for the downshift normal range tables.
    You can get the address from this program or fix it with it.

    LRT, thank you for the response. That was exactly what I needed. I easily admit that I’m a noob when it comes to using TunerPro. That’s why I’m here learning.

    Speaking of changing the shift parameters, are there other tables involved? I thought I read somewhere about rpm base shift points in addition to speed based?

    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.
