Dump Valves: I dont really see a distinction compared to a normal throttle

ISCV : If you have enough resolution on the fly by wire throtte, I dont see why you really need an ISCV at all

Traction control: Definately a good idea to integrate the fly by wire throttle, but on the other hand, for the really fancy traction systems which brake individual wheels, you wouldnt ever want to activate the throttle to shut until ALL the wheels on the car are in a brake state because before that you would be removing power that some of the wheels are still using

Launch Control: Should be possible to do with just the throttle control and the brakes, no spark retard or cut should be needed, but in the case of turbo cars for reasons of lag, im sure its still preferable to have the throttle open and lose power by cutting the spark as it means more airflow through the turbo and hence less lag at the end of the LC sequence

Antilag: As it works currently but replace the antilag valve with a throttle opening instead

Emissions: Not sure what you want to know on this front?

Drivability control : I assume you mean things like if the user asks for full throttle and that would result in an "off cam" splutter or similar then they should just get the maximum amount of throttle that will smoothly accelerate, not actual max throttle if the two are different
Gear sensitive changes might be worth doing too so that in higher gears a small opening of the pedal results in a larger opening of the pedal as the engine response is damped by the gearing, but this needs lots of hours of tweaking and asking people for opinions I suspect
A nice feature might be over 70mph to make it so that the first half the throttle is LESS sensitive so that you dont "speed by accident" as easily, but thats pretty controversial stuff potentially


Cruise control, no need for any hardware, becomes software only
