Does this look right to you? Fuel table
 

Note: This is a naturally aspirated car.
I have a diypnp on a 90 1.6 nearly stock car.
Learning to tune before I go turbo, so yes this car is my first tuning experience.
I am posting up my fuel table and afr targets to ask you guys if the table looks right to you. Yes I know the table is rough and surely needs work. Right now it is still a work in progress and I am mostly working on regular in town driving. So the area inside the white line is what I am most concerned about right now. The reason I am asking you guys about it is because while my afr's are mostly good, the fuel table goes up at the 2900 rpm mark then back down then back up again. I drew a black line on the 3D table so there is no confusion as to what I am talking about. I have been lurking the megasquirt threads here and haven't seen a table quite like it. Yet my afr's are good. Tell me what you think.
