Abstract
An allocation map stored in a ROM in an ECU is set corresponding to the kinds of fuel injection valves. Therefore, at the time of incorporating fuel injection valves into a diesel engine, it is possible to freely set how injection correction amount data read from a two-dimensional code by a writing device is allocated in an injection correction amount map in steps Sand S, separately for the individual kinds of fuel injection valves. Since the injection correction amount map in which the injection correction amount data is arranged with a distribution of density corresponding to the kinds of fuel injection valves, it is possible to change and set correction points with high degree of freedom even though the amount of data recordable in the two-dimensional code is limited. Therefore, high-precision data maps can be used separately for the individual kinds of fuel injection valves.
