The Lambda Target Table Overlay function allows for a fourth dimension of tuning on the AFR/Lambda Target Table. This can be used for a variety of tuning purposes. Examples include altering the AFR/Lambda at lower temperatures, safety functions to richen the engine or for altered AFR/Lambda based on altitude.

Lambda Target Table Overlay numbers are added to the numbers in the AFR/Lambda Target Table. For example a number of 1 AFR in the table will alter the AFR Target by plus one (ie 14.7 will become 15.7). If the table has a number of -0.5 then the final AFR will be 0.5 less.

 

Note: As the AFR/Lambda Target is used for Closed Loop Lambda (CLL), the Open Loop AFR/Lambda Overlay function will also affect the CLL target.

 

The current AFR/Lambda Target can be viewed in the Fuel tab of the Runtime Values window.
