Engine Control Module: Description and Operation
Adaptive Memory Control

    During closed loop operation, the ECU controls the duty cycle of the jet mixture control solenoid based on output voltage signals from the oxygen
sensor. The mean (mid-point) values of the duty cycle are stored in the RAM (random access memory). The last signals received are stored, even when
the ignition switch is turned Off.
