Is it a good idea to log for MAP and LTFT and change the IFR table accordingly?

This only for cells 0-19.

I see LTFT values around 0% for cells #10 and 15 and about -8% at idle and cells like #0 and 1, that's why I was thinkin the IFR table could be something different than a straight line.

The other possibility is to change the MAF curve logging for raw frequency and LTFT.

I know both systems work(IFR and MAF), I just should choose a strategy and not change both as you wrote before:

From what I see in your post is your jumping all over the place and making one area better but then hosing that with changes that are not needed for the PCM
