I'm currently in the trying to adjust idle RPM to get rid of some exhaust resonance, however I'm getting confused by some of the options.

I have listed the following for idle parameters:

KFNLLNST
KFNLLKHM
NLLAD
NLLKT
and 8 different NLLM tables.

Does anyone have insight to the specifics of the tables and which ones are used when? Does it look at all the tables and use the max or sum or something else of each applicable value?

Yes, I'm new to this, thanks for noticing
