Hi :)
I am in time, to prepare my car most fuel economy.
first step was disable egr. Is done and work ok.
Now I wont change soi maps.
My experience with soi is from engine with carburettor.
So, below is original soi map.

Maps view.


Because egr is removed in negative are, i changed on positive, and make all soi more flat.
Different to org SOI.
