Lambda Air Temp Correction

Lambda Air Temp Correction



Axis selection and changing values

This table is intended to be used with Inlet Air Temperature set as the first/x (left to right) axis, and Manifold Pressure as the second/y (bottom to top) axis, though both axis are user configurable to use any ECU channel. Changing the axis values can be accomplished by pressing F3 when the table is selected, then either editing an existing value or adding a new value. Note that if you edit an axis site value, the overall table values will be adjusted so that the shape of the table is unchanged.

Tuning

The Lambda Air Temperature Correction table makes adjustments to engine fueling provided by the Target Lambda table as requested.
An example of where this may be used is to provide enrichment under conditions where high inlet air temperatures are experienced.
Numbers entered in this table are added to the number referenced in the Target Lambda table. 

To add fuel enrichment
Target Lambda value - 0.90 or 13.23:1 AFR
IAT Correction = -0.05 or -0.5
Corrected value = 0.85 or 12.5:1 AFR

Alternatively a positive value can be used to lean the air fuel ratio
Target Lambda value - 0.90 or 13.23:1 AFR
IAT Correction - 0.05 or 0.5
Corrected value = 0.95 or 13.97:1 AFR
