Abstract
A method and apparatus for providing corrected throttle valve opening data to the ECU for calculation of various engine parameters includes computing a throttle opening adjustment value H by subtracting a sensed throttle valve opening S from a actual throttle valve opening D at engine idle. An adjusted throttle valve opening K is computed throughout the range of throttle openings by adding the adjustment value H to the sensed throttle valve opening S. In this manner, an erroneous sensed throttle valve opening S is corrected by the adjustment value H. The process of determining the throttle valve adjustment value preferably is performed at the engine idle state and can be triggered by a physical trigger; by connecting and disconnecting certain electronic devices from the ECU according to a prescribed pattern; by shifting an outboard motor from a neutral to a forward or reverse state; or by other triggering means.
