Problem of throttle opening

I think the throttle opening curve can be understood as the change from 0 degrees to 90 degrees when the throttle is fully closed, or the change curve of the voltage value or resistance value output by the throttle sensor. When the throttle, that is, the throttle opening is constant, the fuel consumption changes, and the fuel consumption is directly proportional to the resistance of the road surface, the resistance of the slope and the resistance of the wind speed. When the vehicle speed is stable, the higher the throttle change curve value, the higher the fuel consumption rate.
