Here's the one I use. If you check the manual, we can officially run up to an E25 blend, issue free. http://www.wallaceracing.com/ethanol-mix-calc.php

Using this and an app called E85 Mix I've been running 95 octane now for a couple of months at an E24/E25 avg blend. Butt dyno can definitely feel a difference in the mid range.
