A method of controlling functions of an internal-combustion engine having electrically operated actuators for controlling engine functions, includes the following steps: detecting control-relevant operational data by a sensor arrangement; applying the detected operational data to a first, engine-integrated electronic engine control system; controlling the actuators by control signals from the first electronic engine control system through a power unit; applying the operational data to a second, external electronic engine control system in synchronism with the operational data applied to the first electronic engine control system; generating control signals at an output of the second electronic engine control system; applying, to the power unit, control signals emanating from the second electronic engine control system for the actuator of at least one selected engine function; and simultaneously with the preceding step, removing from the power unit control signals emanating from the first electronic engine control system for the actuator serving the selected engine function. As a result, engine control is simultaneously effected by the first and second electronic engine control systems such that the selected engine function is controlled by the second electronic engine control system and the remaining engine functions are controlled by the first electronic engine control system.

1. A method of controlling operation of an internal-combustion engine for examining engine functions thereof; said engine functions being at least some of ignition function, fuel injection function, exhaust gas return function, air conditioning control function and fan control function; the engine having electrically operated actuators for controlling the engine functions, comprising the following steps:(a) detecting control-relevant operational data by sensor means; (b) applying the detected operational data to a first, engine-integrated electronic engine control system; (c) applying, to a power unit, control signals from the first electronic engine control system; (d) applying the operational data to a second, external electronic engine control system in synchronism with step (b); (e) generating control signals at an output of said second electronic engine control system; (f) applying, to the power unit, control signals from the second electronic engine control system for the actuator of at least one engine function, selected from said engine functions, but less than all said engine functions; (g) simultaneously with step (f), removing from said power unit control signals emanating from the first electronic engine control system for the actuator of the at least one selected engine function; (h) individually controlling and varying, for testing, said at least one selected engine function by said second electronic engine control system; and (i) controlling engine functions other than said at least one selected engine function by said first electronic engine control system through said power unit, whereby during run of the internal combustion engine one part of the engine functions is controlled by said first electronic engine control system and, simultaneously, at least one of said engine functions is controlled by said second electronic engine control system.
