I'm sure this has been done, but I can't seem to find it. Perhaps it does not make sense.
It seems like our EFIS or an app should be able to tell us the exact FF we should use for a desired AFR, given the engine size, RPM, OAT, and MAP.
I did some (probably bad) math to calculate air mass and came up with something like this for 360 in3 engine like my io-360. Standard temps, AFR of 12:1, volumetric efficiency of .88.
I have in mind that considering the BSFC the FF at max power was about 15GPH, that was how I chose .88 for the VE.
Seems like any EFIS would have all the information needed to provide a hint if the aircraft is too rich or too lean.
Is this a reasonable thing to do, have a calculation for 12:1 for best power, and 14.7:1 for stoichiometric?
