You've heard of "brake assist" in cars? Where the interprets you shoving you foot fast onto the brake pedal, and interprets that as an emergency braking situation and gives you maximum braking immediately, even before your foot has pressed the pedal al the way to the floor.
Well, what you need is "acceleration assist". For the electronic throttle to interpret your pressing fast on the accelerator as a situation where you want maximum power immediately, and slam the throttle body full open as fast as it can, before your foot has gotten to the floor. That is you want it to not just read accelerator position and give you the matching amount of throttle position, you want it to be looking how hard you're pushing on the accelerator, at the rate of change of accelerator position, and anticipate what you want. Sure, it'd only gain you tenths of a second, but it takes a lot of extra horsepower to gain tenths of a second in acceleration.
