I have spent countless hours doing my fuel table on the road. Car is tracking Lamda very close to what i wanted to be however the 3d view is quite worrying. Left side is mine after tune and right side is base map. I understand the graph is meant to be smooth . am I doing something wrong or can it be during peak torque you have more fueling ( around 3.5kish ) and after fueling can be reduced?
Any advice is much appreciated
My table tunned on left has too many peaks and not smooth pattern

same thing with my ignition 3d table, car is NA and doesn't knock / confirmed with base knock levels I had. You will see a spike around 3k which is 53 degree
Should I use smoothing feature?

Once I turbo charge it, I can use dyno to check ignition table as paying £500 for a day of Dyno little unresoable on NA engine
I cant see the photo however depending on what tool you are using I like the interpolate x and y functions with smothens inbetween 2 different points (the first and last selected cell in a range)
The fuel map with typically follow the shape of the torque curve. So it is very likely to need less fuel after peak torque.
