A circuit for generating an rpm responsive information signal for electronic fuel control systems designed to provide intermittent actuation of a fuel delivery system is illustrated herein. In an electronic fuel control system which relies upon excursions of a controlled voltage through a selected threshold level to generate the injection controlling signal, a circuit is provided to control the variation, as a function of engine rpm, of the initial value of the injection controlling voltage. Means are also illustrated for updating the engine rpm information at least once per engine triggering event to provide improved fuel delivery response to variations in engine rpm.
