ABSTRACT:
The gain of the airflow meter electrical circuit is modified as a function of engine speed such that at any given throttle opening the gain over one portion of the engine speed range is different from what it is over another portion of the engine speed range. In the disclosed embodiment gain is greater over a lower portion of the speed range than it is over a higher portion of the speed range so that the airflow meter is endowed with increased resolution at low engine speeds where such increased resolution is beneficial. The invention is especially well suited for a hot-wire anemometer type airflow meter.
