| If you're running a mix (say 75% E85 and 25% gasoline), then you have to do a little more work. As an example, let's assume you're running 75% E85 and 25% gasoline.

| - | 850 * 0.7525 = 640 | + | 850 * 0.7525 = 640 |
| So instead of 570 cc/min that results from 100% E85, your injectors will actually flow like 640 cc/min injectors with a 75% E85/25% gas mix. You can then calculate the global fuel same as always. | So instead of 570 cc/min that results from 100% E85, your injectors will actually flow like 640 cc/min injectors with a 75% E85/25% gas mix.
