contemplating using E85 instead of pump.
I used this :

Flow Calculator

but obviously I will need to get larger injectors my question is more of an opinion
do you really feel that it was worth the change here are some things ive read if some of you could give your own personal experiences. (i know i can run dual maps)

-build up/ gunk? any idea why some people have this problem and some do not i am guessing old or bad fuel?
-drivability (not really to concerned)
-cold start up (i am in NY)

-environmentally friendly
-30-.50 cents cheaper than premium gas
-a little more hp made than with premium gas
-doesn't smell as bad (when running catless exhaust)
-Considered an "Alternative Fuel"....tax deductible
-engine runs a little "cooler"

Am i missing anything ?
Xenocron will be tuning the car i briefly spoke to Chris about it, he was kind of in a rush and i admit there is a lot of information out there but with my set up and power goals it cannot be ignored.
one last question that i have been reading about is ability to have a higher compression ratio less detonation ..
was thinking of 10:1 but now considering higher. Recommendations and experience..
Yes this has been beaten to death but it seems like everything posted has been alot of people's responses are search ok i have.. looking for mature positive criticism.
I will be posting progress as it happens about the build here

to add to some of the things you're asking about
E85 does tend to rot and absorb water when it sits for extended periods of times, I have heard about it ruining pumps when it sits. Make sure you have it available and it is good quality. Also think about whether or not it is a race car or a daily. Some people have been running the GM sensor which allows for mixing e85 and premium and keeps you running the correct afr ratio based on the content. The power range you're seeking may not be enjoyable to street daily or even street, but just something to think about

E85 is great. Its relatively cheap and can sustain a lot more power, but it has its drawbacks - mainly additional fuel volume and its inability to sit for long periods without degradation. I ran e85 in my built daily GSR for ~2 years without issue - I would recommend it to anyone.

What EMS are you using? Certain EMS's allow for blended dual tunes with an ethanol meter - basically you tune on E85 and 91 octane. There are maps between the two that blend the different tunes based on ethanol content. That way in the winter or whenever E85 isn't around, you're still able to fill up and drive it safely without emptying the tank or messing around with the ECU

S300 V3
thats one of my major concerns,
i donot Daily the car and sits for winter it is strictly a toy. read a few post about the lifespan is not reliable

Schister66

The S300 V3 is compatible with the GM Flex Fuel sensor from what i've heard. You may want to check with your tuner on that one - since you're going to Chris at Xenocron, I would imagine he's familiar with it.

As for the lifespan of the fuel - as long as it doesn't sit for 4 months+, it should be fine. Again, if you have the ability to switch from E85 to pump on the fly, it shouldnt be hard to empty the tank of E85 before letting it sit.

I love E85, there are 3 stations that carry it within 15 minutes of the shop here so I have done quite a bit with it. Couple of ways you can daily drive it with the S300 and I am certainly willing to help you design everything around it.

Shoot me an email as its usually a little more customized to each person that generalizing it here on Honda Tech

Does the S300 V3 allow for the GM Flex Fuel sensor and using blended E85 and pump gas tunes on the fly?

I've seen it with AEM, but had heard the newest S300 was capable as well. I'd be interested to get a tuner's opinion on it...

Me too

I havent found a damn thing online or know anyone that has it setup to add fuel and timing

Id be really interested in knowing exactly what the s300 can control

Can boost be added in as well?

Hondata boards are very vague about all this

cleansi

well ive already been in contact with you and your guys,( thanks for the help) I just got the information about who to build the motor, going with CSS then Amaury Lozada,
unfourtunatly i jusmped the gun and bought you black friday deal S300 and ID1k's combo, know considering E85 I know i will have to go larger.]
I decided to go with (9.86:1) comp but would rather bump it some where around 10.5 but it seems Wiesco does not make .25 os around that compression. (wanted to stick with the brand)

this car will not be dailly driven and will sit for periods of time that is why i am concearned about switching to E85.
but i think ive found enough encouragment to switch, i will just empty lines and take during winters when it sits a soppose.
thanks for letting me know you agree with E85 that certainly is another deciding factor.

Any info about s300 e85 and a flex fuel sensor?

0HAMOTORSPORTS

Yes, when used in combination with the GM Flex Fuel sensor, the software will allow you to configure fuel and ignition compensation based on the fuel's ethanol content. Here's a screenshot of the ethanol content compensation tables:



The S300V3 allows direct connection from the ethanol content sensor to the analog inputs on the top of the S300 board. This way no ethanol content analyzer is needed, just connect the E85 sensor directly to the S300.

If you have the patience and time, you can tune the car on pump gas, then tune on E85. Review the two tunes and compare your E85 tune vs. gasoline and see what fuel percentage increase you needed with the E85 (of course take in consideration the ethanol content of that tank of E85) as well as the additional ignition advance you were able to add while running the E85.

Then setup your compensation tables on your regular unleaded tune to compensate for ethanol based on your ethanol tune. The S300 will then automatically compensate/adjust your tune whenever the ethanol content in your fuel changes so it is always optimal

No way to control boost? Say from 91 youre at 10 psi and on e85 16 but with a mix of half and half and ethanol content at 50 will it adjust boost?

0HAMOTORSPORTS

Not yet. Only fuel and ignition compensation at this time.

riceball777

I love my flex fuel tune. The amount of boost/fuel and ignition is all adjusted automatic by my aem ems v2. Forgot about geting an e85 tune. A flex fuel setup really is the best thing since Apple pie. No more switch maps and draining your fuel tank to switch from 91/93 octane to e85. No more fear of blowing up your engine with winter blends of e85 which is really e70 or below. No more driving in fear of running out of e85 because there are no e85 stations close by.

Here's a pic of me running e10(pump 91 octane), e50, and e85. In my area the e85 is usually e80-e82.

Who tuned your car?

Lazysk8r2

im running e85 in my daily, makes great power and torque. Some draw backs are the poor gas milage and you cant drive too far or you might be stranded. In the winter i put 93 back in, sucks trying to start in the cold weather in OH.

0HAMOTORSPORTS

By setting the car up with an ethanol content sensor, you can configure the programming to automatically compensate for any ethanol blend, or even pump 91 gasoline. Then you won't be stranded if you only have a 91 octane station around
