Abstract
An arrangement and a method for configuration of a combustion engine control system, the control system including a distributed computer network having a main computer ECU and a number of node computers, CCU 1/CCU 2/CCU 3. Each node computer is arranged closely to a selected group of cylinders (11, 12/13, 14/15, 16) of the combustion engine and controls at least the fuel supply (22) of each respective group of cylinders. The main computer and the node computers are connected to a common communication loop (1) transmitting control data from the main computer to the node computers and information from the node computers to the main computer. By using dual switch devices (30, 31-32/51a-b, 52a-b, 53a-b ) at each node computer, the main computer as well as each individual node computer can be configured for the present engine type, and the node computers can be configured for the specific cylinders. The switch device preferably constitutes a number of rotary switches of the BCD-type.
