    Trans Spark torque management.. I'm lost

    Working on my turbo ls truck.. Have tried a few different things and Spark torque management keeps popping up and saying trans, when I am starting to roll into boost.. All the trans torque limits are disabled to my knowledge.. Can feel the spark dropping in the truck.. Not sure what else to do.. Any help is appreciated!

    Try disabling [ECM] 321 under torque management.

    Try setting your min spark base timing 12701 to like -10* across all your cells where you have -20* and that should help. Or you could set it all at like 5* and it shouldn't pull timing below that value. And you want your max torque 2869 to be what your actual max torque is or a little above to the crank.

    Under Torque Management - Trans Input Max - Set to 8,192 Nm & set Spark Reduction to Disable
