ELECTRONIC FUEL INJECTION CONTROL DEVICE HAVING MEMORY SWITCHING FUNCTION

摘要

PURPOSE: An electronic fuel injection control device is provided to switch automatically inner memory of an ECU and an outer memory of an A/T board in a connection or releasing of ECU and A/T board. CONSTITUTION: A switching line is connected to a switching terminal(EA) of CPU(14) in an ECU and a pull up resistance(Rp). The switching line is also connected to a connector(18a) of ECU. An earth line connected to an earth of an A/T board(12) is connected to a connector(18b) of the A/T board(12). The CPU(14) switches automatically an inner memory of the CPU(14) and an outer memory of the A/T board(12) by 'low/high' level of a memory switching terminal(EA). The memory switching terminal(EA) is varied by separation and connection of the two connector(18a, 18b).
