2/2/16 Update: has a bug that makes the app display 9% more ethanol mix than desired goal
Needs 2 things
1) to save input data in memory.
2) to fix bug where octane is affected by changing ethanol % and requires gas octane to be ready entered to reset.
Also, needs to calculate the octane based on the e85 pumps octane (via input) and not just the octane of e85(105).
Ex. it needs to compensate for the total change away from e85, if I input the station only gives out e81 at their station (most in ca do 81.5%) but don't know the octane at that pump. Then the octane should be 18.5% lower based on the concentration as well as the e10 in the gas and octane used in the gas
