Lambda Coolant Temp Correction

Axis selection and changing values

This table is intended to be used with Coolant 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 Coolant 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 such as during cold start or where high coolant 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

Coolant Temp 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

Coolant Temp Correction - 0.05 or 0.5

Corrected value = 0.95 or 13.97:1 AFR
