| The 14.64 figure above comes from the chemically correct stoichiometric ratio of gasoline. A lot more data can be found on the [[http://en.wikipedia.org/wiki/E85_in_standard_engines|wikipedia E85 page]]. | The 14.64 figure above comes from the chemically correct stoichiometric ratio of gasoline.

| For example, if you're running 100% E85 with 850 cc/min injectors, your injectors are flowing the equivalent of 570 cc/min injectors on gasoline: | For example, if you're running 100% E85 with 850 cc/min injectors, your injectors are flowing the equivalent of 570 cc/min injectors on gasoline: | ||

| So now you can calculate your new global fuel using the standard formulas and 570 cc/min injector size instead of 850. | So now you can calculate your new global fuel using the standard formulas and 570 cc/min injector size instead of 850. | ||
