Hey guys, I have a 90mm plate kit on the way for my 5th gen. I also have an E85 flex fuel sensor thats been laying around for a while now unused. Just wondering what fuel system modifications if any I would need to run E85 and spray together? Planning to only spray 100 shot to start with a max of a 150 later down the road. Just trying to decide if it will be financially feasible for me to add in the E85 or if I should just sell the flex fuel sensor to recoup some money if it's too much work to get it set up with the nitrous. Thanks.

the issue I could see would be the nitrous tune changing based on ethanol content.

the more ethanol the more fuel. if it is tuned for e85 and you run less than that you will be rather rich.

If that's how it worked it would defeat the entire purpose of flex fuel. The sensors read ethanol content and makes fueling adjustments accordingly. It won't be tuned for E85 specifically. However I am not sure how that would be affected with nitrous added. I know how the sensor itself works, I'm just not sure how it would be affected (if at all) with nitrous thrown into the mix, and what it would demand out of a fuel system (hence the title of this thread). Would a stand alone fuel cell be needed?

the nitrous portion is what I am referring too. if it is jetted for e85 and you run 93 octane, you will be waaaay rich. if it is jetted for 93 and you run e85 you will be waaaay lean. you would have to know what tune it likes for various blends and rejet accordingly. Your timing may also need to be adjusted.

One thing to note, e85 and gasoline tune a little differently.

You will need a larger fuel jet, but you might not need to pull any timing either

Ahhh ok I misunderstood you my bad. So yeah it definitely sounds like a bit of a hassle. That's the info I was looking for. Thanks guys.
