I know this, but some drive by wire cars will open the butterfly in the throttle body while the engine is cranking because of the signal it is receiving from the accelerator pedal sensor allowing air to enter the engine, they think BMW's operate on this theory but our cars don't use a conventional throttle body, valvetronic takes the place of the throttle body in allowing a metered amount of air to enter the engine. When we push on the accelerator pedal in our cars it actually controls the valvetrain and not the TB butterfly.
