Air/Fuel Ratio Rotax Max

I have got this jetting app and it has a air/fuel ratio graph on it.I was wondering what I should be looking for and what would get the most performance

This is for senior Rotax evo

What app is it?

At a glance, I’m not sure how it’s going to help you jet, luckily the Max is reasonably straightforward though.

It’s called “jetting max evo”
