Checking the pulse on E85. Anyone out here thinking about setting up their TRX for Flex fuel or straight E85? The E85 setup for the 6.2 Hemi has some issues with needing near constant ECM updates due to weather and elevation but the Flex fuel looks much more promising for a daily driver.

I will look into it once I get about 5k on the clock. I run it on my CTS-V and it works great,.. If gas shoots up to $5 a gallon I might look into it sooner..

I have my twin turbo viper on E85 and love it. It smells amazing even with no cats. My viper is on full Motec and that works great. Not sure how any other systems would work.

I’m thinking we should see more than 100 HP gain moving to a flex fuel running E85.

Are your running a sensor to monitor the ratio or are you running straight E85?

Hellcat Challenger, Ram
I plan on running a flex tune on mine sometime in the first year. My hellcat challenger is E85, I buy it by the barrel. $200 for a 55 gal drum of true E85. Ethanol wakes these hellcats up. If your in Colorado I can sell you drums for the same price delivered to your door.

I live in WI and E85 is everywhere. I don’t have a problem finding it at the pump. I want the flex fuel setup in case I end up somewhere that does not have E85 at the pump. When that happens I will just fill up with 93.

What is needed to change this engine to be able to run files fuel?
You would need new injectors, thermostat, and a tune to run E85. I would suggest only doing a full time E85 conversion if you have a very steady supply of E85 in your area AND you get/have a good relationship with a local tuner. Doing a flex fuel conversion won't yield you nearly as much performance increases but it is WAY less of a pain in the ass when the weather changes and you aren't constantly adjusting between running too lean or too rich on a daily driver

Sorry that should be flex fuel...lol spell check needed before you hit send
Running flex fuel allow you to run E85. You can. Tune the 6.2 to over 900 HP with E85 without cracking open the engine. Just add bigger injectors to run E85, bigger fuel pump in some cases to support more fuel flow and a tune to support the new fuel setup.

Most guys are also running upgraded pulleys along with the E85 to hit around 900 HP.
