    What causes this TQ Mang. I need help.

    I bought a book and I'm trying to learn this stuff.
    What TQ Managment is pulling timing at each shift ?
    What cause the commanded afr to go rich for a little bit ?

    I thought all TQM was removed on this tune, hmmmmm

    Theres still TM in that tune on the trans side.

    Trans->Torque Management-> Torque Reduction (section). Pattern X and Downshift have TM left in, I would imagine that's where it's coming from as Pattern X is the only one that's set to be used in your tune.

    Also, not sure if you want/care but setting Engine->TQ Mgmt->Brake Torque Management ->Disable by TCS to Enabled will remove any BTM events if you turn TC/ST off.

    Much better, Thank You !
    That is like 9/10ths of a second difference from 25-85 mph at 6psi.

    Now on to maf low to get it a bit closer, then wot, that wot fueling is off by A LOT !
    Looks like I need to lower wot timing a bit till I get the fueling correct.

    Thanks Again for your help and advice,
    Much Appreciated !

    Definitely not getting any timing pulled now!

    Get that WOT fueling dialed in and it'll look even better.
