Mirage L4-1597cc 1.6L SOHC Turbo (1985)
Engine Control Module: Description and Operation
Adaptive Memory Control
When in closed loop operation, the ECU monitors output voltage signal from exhaust oxygen sensor and stores in a Random Access Memory (RAM)
the mean values of feedback gain. The last mean values are always stored.
When in open loop operation, the fixed pre-set fuel delivery time is modified by the ECU with the mean values of feedback gain to improve emission
performance.
