I need to get a Nominal A\f Number and all i have is the Fuel O\C And H\C RAtio. Does anyone know what The formula would be or if there is a gernerator on a site i can use?

So is this 10.33:1 E85 AFR the equivalent of a stoich 14.7:1 gasoline AFR???

yes but it varies with blends as so with regular fuel. All your books and what will say 10:1 for e85 normal and 14.7:1 for fossil fuel.

But The're incorrect as it is variant on; mostly H\C in fossil fuel (most dont have a oxygenizer) and with ethanol it changes with o\c and h\c ..

not much though normaly not more than one point..
