Adaptive fuel stratergy

The adaptive fuel control strategy is designed to compensate for variability in the fuel system components. If, during normal vehicle operation, the fuel system is detected to be biased rich or lean, the adaptive fuel control will make a corresponding shift in the fuel delivery calculation. Whenever an injector or fuel pressure regulator is replaced, keep alive random access memory (RAM) should be cleared. This is necessary so the fuel strategy does not use the previously learned adaptive values.​
