3.2.4.1.8.3 Target map
The A/F target map constitutes the same map structure used in the parameter maps for fuel/ignition.
The values input here constitute the target A/F ratio. The A/F ratio feedback or lambda control will
strive in each map position to control the A/F ratio towards this target value. This means that you
can drive with minimized consumption in the partial load range and fulfill the requirements of
emission laws. Towards a full load a richer A/F mixture can be automatically delivered, for the benefit
of power and cooling capacity of the engine. The adaptation of values in the target map works in the
same way as with the main maps (ignition/injection). When you input 0 in a frame, the A/F ratio
feedback control will not be active in the relevant range.
In the figure on the left side on the next page is a recommended target map shown for a N/A engine.
Below that is a recommended target map shown for a turbocharged engine.
