Not in my diesel!
My focus is fly by wire throttle. The fuelling is determined by throttle %, engine speed and vehicle speed. The fuelling is further limited by the air density limit map, which is relative to boost so smoke is reduced to reasonable levels.
There are 4 throttle position and engine speed maps, with vehicle speed interpolating between these maps.
Oh, and there's a temperature dependant map too plus lots more
So, no. There is not much correlation between throttle position and fuelling unless the conditions are exactly the same.
