PROBLEM TO BE SOLVED: To eliminate requirement of rewriting many maps in mounting and replacing an electric resistance for injection amount control and to reduce unevenness of actual fuel injection amounts caused by difference of individual fuel injection devices. SOLUTION: When Q control resistance 20 is mounted or replaced, an electricity turning on time calculation part 102 of a controller compensates Oelectricity turning on time data at every mesh points of an injector according to compensation injection amounts described in electric resistance and rewrites an injector map. Scales of injection amount reference axises of the injector maps are same between before and after map rewriting, no rewriting of other maps having the injection amount reference axis is, therefore, required.
