E85 NO MORE!!! Now called Flex Fuel ethanol and is lowered to E54
Nothing bothers me more than when ppl call E85 "Flex Fuel". The term Flex Fuel means that no matter the ethanol content, your vehicles ECU will adjust the maps accordingly to provide the best performance on that mixture. Ethanol is NOT Flex Fuel...Ethanol is an ALTERNATIVE Fuel. Flex Fuel is an Adjective as opposed to a Noun haha
E54 is obviously a 50/50 mix and quite honestly, very close to being pointless to use! anything under about E35 is an Inefficient mixture of Ethanol/Petrol. E15, which most station use these days, is the close to the maximum amount of Ethanol you can use w/o leaning the AFR out...ive used 20% before w/o any problems but once i hit the 30% mark, the mixture was starting to be a little too lean and causing occasional backfires. You wont see any performance improvements until around E50, and you really cant start advancing the Ign Timing until about E60. It wasnt until E70 to where i started to make significant gains, and from there up is where you start to have fun!
Point is, there is no Point in using E54! LoL

Yea he's completely incorrect, my car is able to produce more power through the blend tables the higher the ethanol content gets as has been proven by many others.
At E-30 my car is making a bit more power due to the blending tables and cars ability to take more timing and boost over straight 93 oct, I've seen the graphs at different mixtures from 93 straight through to E-85 and TQ and Power go up with any ethanol content above like E-14 in my car.
Obviously if the car is not tuned for the different blends it's not going to mysteriously make more power and lean out obviously as the higher the ethanol the more fuel required.
100% not useless

you obviously have never tuned your own car or been involved in tuning your car. I'm not talking about watching the tables haha any retard can see that the tables change as the mixture of E Increases. I'm talking about actual gains. Not 1 or 2 hp/tq... I said SIGNIFICANT Gains. 20-30+whp. You won't start seeing Significant gains until you reach a 60% mixture. I also said that it's not until a 30% mixture to where it's actually efficient.
I own an Evo8, STi, and a 70 Chevelle with LS7 and 6266 kit on it. All of my cars run on Ethanol now, and all have been tuned more times than I can count, on a Mustang Dyno. I've sat and watched my STi get tuned for hours on end for weeks straight.
And you are basing your Info off of what? Watching the fuel/ignition tables?
Using E54 is Pointless! Ur better off using Meth Injection
Here are some examples....



gtfoh...

Yea I'd get a new tuner if I were him, and no dude I've see the graphs exactly like the graphs Bryan just posted as E content goes up the car has the ability for the tuner to make more power so power goes up. Maybe ask your tooner why yours does not? or don't I don't care either way.
I know perfectly well what my care does and hell I thought this was common knowledge, though after the flat or round earth thread it amazes me what people think to be true anymore.
Best of luck!!

So if I have an Evo IX and can't find a damn FiTronic to save my life in south cali, how would I go about getting it tuned for e85? We just got our first e85 station in town and it has the 51% - 84% sticker. Would I have the car tuned at 51%? Or somewhere in the middle around, say, 67%?

You should be checking the alcohol content to confirm. Every time I have checked it shows a solid 85%
Did you get tuned at 85%? what would you have to do if it did actually drop to 70%?
. I called Propel not long ago & the manager I spoke to noted they strive for a solid 85% all the time.
I have checked the content at every fill, & so far every batch has been 85%
