Basic idle help

[LuhrsTSF342]

I think I have the higher RPM stuff figured out but the idle stuff has me,
Can someone give me the basics for idle on a 230-236 114 cam in an LS2 ?
I've been told I should have more timing that stock and be richer.
How can I get it to idle at 13:1 (I'm assuming that's what I need to do) if the PCM wants to bring it to stoic?
Any hints to get me started?
Thanks, Robert

No reason to idle that rich. Stoch is fine on the LS2's.
You want to look at how much airflow is being used at idle and then adjust the base airflow around that airflow value.
Also move the startup airflow up 2-3 g/sec.

Spark: Should be ~25-35 degrees with that cam at idle.
