MAF comp vs coolant

I use speed density 9417 and my issue is that I have an annoying rich warmup cruise (closed loop system not fast enough to compensate). If I drop MAF comp vs coolant temp table to solve the issue, it's my idle that will suffer: it will become very lean. I don't really know how to avoid the situation, as these tables compensate the MAF for all HZ values.

As soon as the car gets to operating temp, the trims are near zero and there is no rich cruise or lean idle


What is the difference between these two tables?
MAF COMP VS COOLANT TEMP 1
MAF COMP VS COOLANT TEMP 2
I always used them as one table, but never knew in which condition each one is used by the ECU...

Good question, I'm pretty sure MerlinOZ may have the answer?
