Torque Model: Normalized Torque, Optimum Torque Table and Torque to Load Discussion.
There is a lot to cover here including lowering normalized torque to increase power and associated effects (e.g. on transmission and tcu tunes).
The formula/heuristics of how the ecu internally calculates torque.
The internal torque calculation versus actual output of torque and associated errors P061A and P061B.
