Spool Ethanol Analyzer

The calculator is nowhere near precise enough as it should be. It should not round gallons needed to the nearest whole gallon. Fuel tank size should be adjustable by 0.5 gal instead of 1 gallon. Same thing with all the estimated ethanol grades. Should be by 1% and not 5%.

The analyzer and the app are flawless +1yr in. Was far more affordable than FueliT

The best app for e85!!

I'm sure this would be an easy update, email your developer and ask him/her to add this option! If there is no update then I will be forced to go with other competitors offerings.

Pro: This is a great app that allows you to calculate how much ethanol you need when running a mixed fuel tune for example e50!! Wonderful app!! Con: only works for one size fuel tank.

This is my favorite application to use for creating mixes while filling up at the pump.

Works but need to make the fuel level gallons adjustable! Thanks!

Please allow configuration of fuel tank capacity.
