Abstract
Engine-control device, in which an internal combustion engine coupled to a transmission group is controlled by a central electronic unit which receives at an input a plurality of information parameters measured in the engine and calculates control signals for operating groups of the engine itself. The device comprises an external processing unit communicating with a control circuit of the transmission group and with the central control unit. The processing unit is capable of being activated by commands originating from the control circuit to modify the control signals, regulating alternately the torque generated by the engine and the speed of rotation of the engine itself.
