A fuel injection controller includes an ECU controlling an operation of a fuel injector based on a characteristic data of the fuel injector, an EEPROM provided to the injector, and an EEPROM provided to the ECU. Identification information by which the fuel injector is individually identified is stored in both of the EEPROMs. It is determined whether the identification information stored in the injector-side EEPROM is identical to the identification information stored in the ECU-side EEPROM. Based on this determination result, it can be determined whether the injector and/or the ECU are exchanged to new one.
