you dont have the whole formula for it? I better start learning 'if then else' exel- programming.
Just wondering that if my 287g/s @ 6700 gives 12.23 AF how come stock fueling is unofficially rated to 310-315g/s? I have once logged 317g/s with 003 so I can now use this 100% (18.18)to calculate the af at 6600rpms and 317g/s witch is about 13.5 and very lean!
Is there something I'm missing here?

It's often recommend to at least upgrade stock FPR to a 5 bar (which changes the formula obviously)-
Also 13.5:1 is not 'very lean' in my opinion, although I would not want to go any leaner. Remember a stock S4 runs close to stoichometric (14:1) at full boost/WOT, if that were dangerously lean for the motor, I doubt Audi engineers would have programmed it that way.

Thanks, I hope piggie will be able to help in the near future with ...
his fuelin combo. remember I have the weak bosch maf so bigger housing is needed to get some more air. Currently I'm happy with 300g/s and stock fueling.
