    Default 6L80 TM removal?

    I noticed that on the new 6L80's you can only select to have TM on/off. On my 4L60(Silverado) you could remove any percentage you want. Is it something that will be getting updated soon.

    My brother has a new 2010 Camaro and with the TM on off it shifts too hard at the track and spins into 2nd and 3rd. What can I do to soften it up a bit?

    Here is what they wrote on another forum. Can anyone confirm this.

    "I do not use EFI live but with HP tuners torque management is adjustable.
    It works on a combination of tables (Shift torque factor, Shift torque factor adder, Adder modifier & Cold multiplier).
    The formula for it is ((Shift torque factor adder * Adder modifier) + Shift torque factor) * Cold modifier."

    Is EFI Live working on a solution for this?

    We have been wanting to expand on the 6 speed TCM tables for sometime now, it's just one of those really hard computers to work with, well, I should say, to figure out what the heck is going on.
    Reality is we probably won't get to the T43 again until early 2010. But I can assure you it has not been forgotten about.

    Cheers,

    Any more updates on this? I have a 2010 and with TM off I really dont like how it jerks you slowing to a stop as it downshifts. I was told this was due to TM

    FWIW You can work around it a bit by limiting the amount of timing being pulled.

    Nope.... Nothing to do with Torque Management.

    The shift schedule is controlled by a few things.... Throttle angle, MPH, and a few other things....

    Depending on the rate of decel and the corresponding throttle angle (how far your foot is into the throttle) you can get that side effect.

    While TM is involved, I would prefer to modify your shift schedule to lessen "jerk" you're seeing.

    Call me.

    Thanks for the advise Chuck.
    It was most noticeable with my foot off the throttle slowing from say 35 to a stop light
    I hope to finally get around to re-installing EFI live on my new Windows 7 machine so once I’m up and going again, I will get with you.
    (I hear there are some new videos in the works, can’t wait to see.)

    This is very good advice.

    I have TM fully engaged, but I modify the minimum final timing spark table (B5157) to reduce the timing reduction at higher rpm and loads. This way, I have smooth TM upshifts and downshifts at light throttle, and screech-bang shifts at WOT. It's the absolute best of both worlds.
