Pressing the gas pedal (info)

I got the following information from the shop manual.


The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the accelerator
position and sends a signal to the ECM.
Accelerator pedal position sensor has two sensors. These sensors
are a kind of potentiometers which transform the accelerator pedal
position into output voltage, and emit the voltage signal to the ECM.
In addition, these sensors detect the opening and closing speed of
the accelerator pedal and feed the voltage signals to the ECM. The
ECM judges the current opening angle of the accelerator pedal from
these signals and controls the throttle control motor based on these
signals.
Idle position of the accelerator pedal is determined by the ECM
receiving the signal from the accelerator pedal position sensor. The ECM
uses this signal for the engine operation such as fuel cut.

Does this mean that pressing the gas pedal faster yields different results than easing into the throttle fully?

Is that the same as drive by wire? If so, that is what I was reseaching. I was looking into the control system (particularly the grounding) for the throttle control.

yes. everybody has a different name for it. Did you get Black Bettys grounding kit? it really helps with ATs throttle response.

^^
so does that mean that the ecu optimizes the input and essentially tries to save the most fuel ? does that make sense ?
