    More edit table under trans.

    Mainly talkin about ls2's with separate TCM, I keep reading everybody quikie trans tune write ups, they can adjust shift timing or quickness. Can not on a ls2 TCM??? or this somehow a function of FMC postive and Negative tables?

    Is there a way to get to all parameters in TCM.
    Cause 1>2 part throttle is harsh at best but 2>3 shift scary soft.

    thanks

    Hmm. I see your point. Only FM +&- to play with and MAX...
    Sounds like a Q for Chris.

    Another trans request (probably very uncommon request anyway)
    Can we view/change the gear ratios for the transmission?
    Eg.
    4L60E 1st=3.06 2nd=1.63 3rd=1.00 4th=0.70
    4L80E 1st=2.48 2nd=1.48 3rd=1.00 4th=0.75

    Thinking along the lines of a 1st gear ratio change for a performance application..

    Yes, that would be very nice to have. I am thinking specifically about the trans gear ratios in the E40 PCM (LS4 cars)

    ok guys the latest 2.1.11 beta includes extra params for the trans. Please email support@ or PM a mod for the URL if you don't have it.

    i looked at the ratio stuff but there is a whole bunch of tables, values and shift progression/timers tables that need modifying for a ratio change. I'll need to look into it a lot more. Unfortunately i was hoping it would be just one number as well...

    Normal = not performance/tow mode
    brake/power on means the brake element is applied and engine is transmitting power to the trans (ie. accelerating).
