When a learning value of a fuel injection amount is lost through the replacement of an ECU, an issuance device is connected to the ECU to send a forcible learning command signal, thereby forcibly making a shift to a fuel injection amount learning mode. After that, racing is carried out a plurality of times only through a single accelerator depression operation by an operator, and about 10 learning values are acquired every time racing is carried out once. When the learning values are acquired a plurality of times and learning is completed, racing is ended. Thus, a learning operation can be completed at an early stage after the replacement of the ECU. As a result, there arises no deviation in the fuel injection amount. |
