I basically have a quarter of a tank empty..

Its pretty simple... If you have around 3/4 tank of straight 93 right now, just top it off with E85 and you'll be good to go, it'll be close to a 75/25 mix

Or if you want a really nice kick, you could even wait until it gets just above 1/2 tank and then top it off with E85... that would get you close to 50/50 which is what I'm running now, and its been running great!

Then the next fill up, after you run it down to 1/8 tank, you just add the percentages of each to get the mix you want.

Hey so does your 50/50 mix feel like 110 race gas? I dot have E85 anywhere near me but I do have 110 VP race gas just wanted to know what's the comparison. And if we just run race gas might as well go to map 7 correct?

It does feel like race gas once it brings boost up.

E85 has other plus that race gas does not have.

I've never ran race gas before so I wouldn't know. But I do know that the newest firmware's map5 on a 50/50 E85/93 mix, is very comparable power wise, as the old map 3 on meth!

And the new map3 (5/19 firmware) on 50/50 E85/93 and 70/30 alcohol/water is just crazy fast!! Just this morning as I took off from a stop, I just rolled on the gas hard as I was going around a sweeping corner and my xi went into a 4 wheel drift at 50 mph while exiting the turn!!

The reason I ask is cause I'm about to do some pulls on a modded WRX and trying to decide what map to run

Jesus lol I just like map 2 for the quick boost but I want that 16lbs lol

I am soo pissed the nearest E85 station is an hour away from me. May have to bite the bullet and make the drive out.

Yea me too I think I'm gonna make the 30 min drive to get so E. anyone know how long E85 can sit in a gas jug before its too gross to run through the car?

[M3 Eater]

I have the newest firmware from terry. It doesn't even have a date in title. Car feels so strong I may not use meth again. Never did I think that an auto tune map could show so much dynamic range. On 93 only it's showing 14-16 and with a 50/50 mix it will jump to 15-17 in just a few pulls. Once adapted, my car feels every bit as fast as map 3 with meth except much smoother. My concern lies within the alcohol in 93, e85, and meth together. If I use 93 with 10% ethanol, e85 that's only 70%, and then spray meth on top, will that be too much alcohol and not enough petrol for the car to produce reliable power? (is there such a thing as too much of a good thing?). I was thinking of downsizing my meth nozzle and just starting to spray water only to control temps while using 50/50 mix.

I was reading that E85 has a longer storage life then regular pump...
Store it in a cool dark place..

Some answers to the "will e85 destroy this or break that" questions. It comes from e85 producers so take it with a grain of salt. Also look at the gas station in the beginning of the video. Pre mixed percentages of ethanol. That would be sweet!

bump the meth additive to 55+ if you are running a 50/50 E85/93 octane mix with at least a 49/51% methanol/water mix (it'll only peak at 17.5psi, but the boost won't taper as much as it would on the regular 30-40additive without an E85 mix), you'll find that the car becomes an absolute monster in 3rd and 4th gears.

hmmm video is interesting, i really want to try the E85, how long did it take for your car to learn the new fuel?

Here's a VD graph of my car, FBO 50/50 e85/91

What program are u using for your VD? And are u using meth along with your 50/50?

[5soko]

Hey guys just tryed E85....

BEAST!!!!!!!!!!!!!!!!

This stuff really works! Im actually happy with the results.. Not a gimmick lol..

I did a really low mix as i wanted to start slow..
3/4 tank of 93 octane and i filled the last quarter tank to full with E85, 5.1 gallons of E85 to be exact.
so thats about a 25% mix of E85? I paid $4.30 for 93 octane and $3.30 for E85 lol a dollar cheaper for E85

Anyways, the car pulls and responds amazingly!!
FBO With no meth on map2 i was peaking around 14psi or so and my timing was a bit jumpy.

With this stuff, i did a short log, im at about 16 psi!!! timing is steady!! tapering to around 14psi @ 6500rpm..

Ok gotta go drive more! Map5 with E85 = Beast.

Its called Virtual Dyno. That first graph I changed the air temp from the default setting of 77 degress fairenhiet to the actual air temp when I took the log to 60f. Here's an untouched graph of the same log. I know these numbers are optimistic but I'll post a graph comparing my best run on cobb stage 2+ aggresive.

My car has no meth injection...yet. Just AR downpipes, bms dci, ets 7" fmic, and jb4 15 ohm board running the new map 5 on 50/50 e85/91.

Here's a fourth gear log on cobb stage 2+ aggresive

Gotta appreciate those Cobb AFR's
