e85 questions

[IrishStallion]

I have been running E85 w/ tune for 2 years and 10k miles and have never checked the pump % nor device % of ethanol. Car will adjust accordingly within reason.

Sounds good. Thanks for the assurances guys.
I tend to over think things a bit sometimes.

I will say that I'm loving the feel on this flex tune. Feels a bit more aggressive and smooth at the same time. MPGs have gone down, but only from 23 on gas to 19 on e85. It's a good trade off given the cheaper fuel costs and better performance.

For sure the power is there and fuel costs even out the lower mpg. Easily the best bang for your buck mod on this platform.

Flex fuel cals are really the best option, we have been building flex fuel tunes on multiple different platforms and it really helps get the best of both worlds becasue you dont have to plan roadtrips on routes with e85 pumps the whole way or panic when you cant get an e85 pump. Here is a dyno sheet to a 2018 with the 10 speed we did upgraded exhaust and flex fuel on with the tank not even 100% e85 and these were the results
