I have searched for the same, from what i have researched i assume :
Engine speed (from ECU or ABS - because it reads wheel sensors - no speed sensor in DQ250), Vehicle speed (mandatory only for DQ500), Brake signal, Acc Pedal position (ECU), Throttle plate angle and Engine Torque (on me7.5 i need to see what is measuring), and probably Engine Load (not sure for this).
Thank you that is what I thought. I was really asking as wondered what the standalone DSG controllers used to control them. Assuming they where only used in manual mode, would it be enough to run the DSG with just speed from abs brake and accel..
