I wouldnt know for sure but on the E31 it seems that the throttle opens a bit more after the kickdown is depressed, kind of like the regular throttle cable cars are. How I could tell was when I was holding a lower gear and testing the operation, delay from peddle action and how long it seemed for the throttle bodies to fully open up. Im sure you can get a realistic answer by checking resistance in the peddle end of it.
just a guess...
