I have been reading for quite a while, trying to comprehend how ME7 responds to the driver's throttle input and wanted to see if someone can help me make sense of what is going on.
When at part throttle I can partially increase throttle input to say 30%, only to then hold the pedal constant, and subsequently watch ECU requested throttle output drop to say 15% shortly thereafter (with a corresponding "feel" to the car and rpm drop while maintaining a constant cruise). This is always something that has bothered me about this car, is it makes the driving experience even more less coupled to the engine output. From my understanding it is some sort of requested torque response to make the torque output of the stock S4 constant/smooth in stock form.
I would like to tune the system to allow for a more direct throttle response at part throttle. However, as much as I am trying to read and understand what may be going on, I can't come to a solution of how to solve this issue.
When you press down on the pedal, that changes how much TORQUE is requested, since ME7 is a torque based control system. It can change how much torque is produced by air charge(slow path) and ignition angle(fast path), and also the throttle plate.
Read TTQS's "tutorial" on tuning. It provides a brilliant explanation of the control system in ME7, IMO.
EDIT: what phila_dot said. I was getting mixed up with torque intervention.
