    I'm really happy to read that everyone has had great improvement with the torque tables.
    Which version of the software is this? I can't find it anywhere in RC10 - is there a newer ver now?

    Oh nevermind - I see that RC10 was replaced by a public release I missed... going to upgrade now!

    Interesting...going to have to play with that on my E67/T42 TBSS soon then! Working on a few other tricks for it now (running a car TCM OS so the TCC doesnt unlock when letting off the gas, simply using the car OS instead of the stock one netted me a +1mpg on a 650mi round trip) and just got my efans installed.

    Should I try blanket adding like +10% to the torque tables and seeing how the trans shifts?

    Yes, just do the ones mentioned in the thread (there is lots of them), see how it feels at 10%.

    so has anyone else played around with b3001 - b3003 yet?

    I have increased mine but I havent done any wot runs, just along with the existing 15% increase in the other torque model table shifts are pretty firm at mid to high throttle. which is what i expected having only adjusted the 40-100% table.

    Absolute Difference

    These will make a difference, but, a much smaller one. In early testing these were the only tables we had put in. Putting the values from a LS7 in to a L98 made a difference, just not enough. But it certainly wouldn't hurt to change them.

    The thing is, to get the desired results there is really only one table that needs to be changed, changing it (at least on a non VVT engine) is very simple and doesn't need to be scientific, plus you can log a PID that shows the torque value so you know how much things changed. I look at it from this approach, you stick a BluRay disc in the player and press play, do you have to know the technical details behind how the picture gets to the screen or do you just sit back and enjoy the movie for what it is.
    There is no more 'raw' data than what you see on the screen.

    I'd prefer to know how the torque estimation happens, or at least what variables are involved.
