In a method and a system for engine control an engine control signal is generated on the basis of a signal produced at each moment from at least one sensor for detecting the operating condition of the engine, the control signal being used for engine control. In order to attain the proper engine operating condition, data representative of the detection signal from the sensor is adjusted in advance, and data for correcting the sensor output is calculated from said adjustment value, the correction data being stored in a memory. While the engine is running, the data representative of the detection signal from the sensor is corrected by the correction data stored in the memory, and this corrected detection signal representative data is used to produce the control signal.

An engine control system wherein an engine control signal is produced on the basis of data representative of a signal detected from at least one sensor for detecting an operating condition of an engine being operated said system comprising: (a) means for adjusting data representative of a detection signal of said at least one sensor in a manner to attain the proper operating condition of the engine; (b) a memory for storing correction data corresponding to a correction value of said data representative of the detection signal in response to said adjusting means; (c) means for producing said engine control signal on the basis of data representative of a detection signal from said at least one sensor and said correction data stored in said memory; and (d) means for controlling the operation of said engine on the basis of the control signal produced from said control signal generating means. A method of operating a processor-controlled engine in which processor-derived control signals are produced in response to output signals from at least one sensor means for detecting at least one operation condition of the engine comprising the steps of: (a) obtaining a reference value in response to an output signal of a sensor means for detecting a preselected operational condition of the engine for a prescribed state of operation of the engine, which reference value is representative of the amount by which the value of the output signal of said sensor means is to be modified in order to attain the proper operating condition of the engine; (b) storing, in memory, a correction value corresponding to said reference value, in dependence upon which processor-derived control signals are produced; (c) for a predetermined operational state of said engine, modifying a value representative of an output signal of the sensor means for detecting said preselected operational condition of the engine using said correction value stored in memory; and (d) producing an engine control signal on the basis of the modified output signal value obtained in step (c).
