yes
when you open the throttle
there is a large increase in injector pulse width of relatively short duration , followed by a milder increase of what the average injector pulse was at cruise
the amount of the increase depends on the load determined by the ECM .
there are many variables taken into account .
the ECM focuses on rate of change of the TPS. the actual value at any given time is less important than how quickly the value is decreasing or increasing
the ECM uses this input to mimic the function of an accelerator pump in a carburetor
after that the load sensor , MAP or MAF is the primary input to determine injector pulse width and the whole mess is corrected by inputs from the AFR or 02 sensor or sensors if the system trims on both front and rear
there are many other inputs also looked at to determine IPW
that is a simple version to answer the immediate question
