  • Patent number: 4972340
    Abstract: An engine control system has a CPU (central processing unit), a ROM (read-only memory) and a RAM (random-access memory) backed up by a power supply. Only in the case where the difference between the data in the RAM and that in the ROM is within a predetermined range will the engine control inputs be regulated by use of the data in the RAM.
