Just want to see who is running E85 with flex fuel sensor. And how they like it?

I run e85 and flex fuel sensor in my turboed small block street car. Works great. Where I am ethanol ranges from 70-85%.

Ditto to what he said^

Its especially nice when the pump E85 mix changes for the winter.

Check youtube, flex fuel sensors read water as ethanol! From what that video shows they're not reading ethanol directly but rather gasoline and then assuming the rest is ethanol.

I run E85 in my avalanche maybe once a month....its a nice wake up for the truck...seems peppier but it sure burns through it A LOT quicker!
The only thing i have heard about running E85 is to make sure you are as empty as possible when switching over from gas to E85 and visa-versa and put in more then 5 gallons or the computer wont know you have switched and that's when people start having issues running their vehicles on different fuels...
Around here the E85 is about .50 cheaper then regular....so for me it aint worth running E85 for less mileage.....with regular gas i get around 14mpg city driving...with E85 im running 10-11mpg...

I don't know what youtube says, but the flex fuel sensor does not see water as ethanol. If it did see water as ethanol, the ethanol content would be constantly changing. I have been running e85 for 8 years now. My car has sat for up to 6 months at one point and my ethanol sensor always reads the same as the last time the engine ran. I have a lcd display permently installed which shows my ethanol content real time and my aftermarket ecu displays and always logs the content. I live in a humid area and never experienced a problem with water being absorbed in the fuel.

IMO there is so much misinformation about e85 on the Internet, mainly by people that have never used it.

Found this guy / shop looking for other things.....https://www.facebook.com/DSX.Tuning

He makes an Ethanol % and Fuel Temp gauge for the GM Flex Fuel Sensors he installs / tunes to convert non flex fuel EfI cars.

This guy seems pretty smart.

So e85 is actually available at the pump? Never seen it....what's the advantage for a normal passenger vehicle? Fill up twice per week instead of once?

How about 13to1 compression out of pump gas.

Mr Maine

14 apache, don't you really need the higher compression ratio when running alcohol to compensate for the loss in fuel energy? I understand there is advantage when running modified engines for drag racing etc, but I just meant being available at the pump for a daily driver.
