    Abbott.....Heres why scaling using just stoich AFR and Injector flow rates make sense...

    If you double the air to fuel ratio, you are saying that the fuel you are using takes twice as much air as previously needed. The computer sees that you need twice as much air per amount of fuel and then cuts fuel in half(compared to normal stoich). The computer will command the amount of fuel (based on the IFR table) needed to complete the combustion process at this doubled afr. Now if you are reporting (tricking) the computer into thinking the flow rate is half of what it really is, then the combustion will come out to be at a true stoich of 14.7.

    ie....tricking the computer to think it needs half the fuel it really does.....also tricking the computer to think it is delivering half the fuel it really is.

    example....

    Normal 14.7 stoich....at 14.7 g/s of airflow the computer needs to deliver 1 g/s of fuel.....

    now for the scaled 29.4 afr...at 14.7 g/s of airflow the computer delivers .5 g/s of fuel....buttttttt with a 50% scaled injector flow rate table it is actually delivering 1 g/s of fuel
