Abstract
An electronic engine control apparatus includes a digital computer which receives sensor signals indicative of various engine operating parameters and calculates corresponding settings of actuators used to control the energy conversion process of an internal combustion engine. The apparatus has a memory for storing and holding data independently of an ignition switch being turned off. The apparatus includes a data input for inputting data specifying a function to be performed, a memory location and a numeral. The computer is programmed to perform the function using the numeral and the memory location. The function to be performed may include modifying data in the memory location in accordance with the numeral.
