Ethanol Calculator

[AWDGT2]

I thought I would share this, hopefully it can make someone's life a bit easier. It's an excel sheet that will auto calculate how many gallons per, to get the E content you are shooting for. It's set up for E85, but you can simply change that value on top and it will auto re-calculate all the fields below. It can be printed and kept in the console for quick reference.
It's work in progress, but the other tab will calculate what your total Octane rating will be by the amount of E you have. Once I fine tune it, I'll upload the full Excel sheet.
