I have a b18a, pretty much all aftermarket and i am almost done building it. My question is, Is there way, compuer work (ecu programming or hondata like tuning) or any engine components ( feul injectors or sensors and ****) that would be able to make my engine run on e85. Ive heard that theoreticly any engine can run on it but it would take some modification. I love driving and im tired of paying out of my *** for gas, and it's 105 octane so there would be a great performance jump. All the guru's out there!!! Help me!

 

I could be done fairly easily.I don't know the fuel system material capability's,but I think the industry has made adjustments over the last years because of some of the current gas blending.But remember it takes about twice the volume of 99% pure ethanol to make the same power as gas.If your getting 300 mile out of a tank now,figure on filling up every 200 miles or so.You would be able to raise the compression ratio some to help on power.

Octane doesn't give you more power, I'ts the more boost, compression, timing you can run with higher octane that gives you more power FYI. I'd think with a AFC and maybe bigger injectors it should work.

How would a wideband work with this mix? doenst' ethanol prefer a richer condition than gas? And would it read the correct a/f ratio from the exhaust also?

 

Thats why i believe the ecu would have to be programed to run on the ethenol becuase of the different burn characteristics. I would like to find somebody that can give me a lift of the things i need to make it able to run on e85.

I know the innovate LM1 wideband has settings so that you can set your theoretical stoichiometric ratio for different fuels..

 

Sweet, can you hook me up with that number so i can have a good talk with that company.

 

Get in contact with Hondata http://www.hondata.com .The can help you with ecu reprogramming and injector/wideband recommendations.Personally I don't think your fuel savings will ever outweigh your cost to convert.

but 105 octane, at 1.80 a gallon and its enviro-friendly theres no downfall

 

WTF 105 octane for 1.80, Damn it 92 is like 2.30 where I live

 

Its because its 85% corn ehtenol gas, the best race gas is a mix of a whole bunch of stuff, including ethenol

 

Hey your from Minnesota too! where in the hell in Minnesota are you finding a E85 pump? I haven't seen one my whole life.

 

holiday only, right in the middle, the big orange one. FYI holiday has the best gas around. 93 octane premium and its low emmisions, =less residue=cleaner engine burn

 

Hmm yeah theres no holiday stations near by here, the nearest holiday is atleast an 60 miles away, You live near the cities or somehting?

 

yea south metro, too bad theres no holidays near you.
I wrote an e-mail to hondata, hopefuly they will get back to me.

 

The price per gallon of E85 would need to be almost half that of regular gasoline to break even as far as dollars/mile of fuel.This doesn't even factor the cost of conversion.The "ideal" air fuel ratio of gasoline is around 14.7:1.Ethanol is closer to 8:1.Octane of pump gas is more than adequate for normal street performance use.Higher octane in a stock engine just means the combustion process is slower.This means less power and poorer fuel mileage.If saving money is the object E85 is not the way to go.If our fuel prices get over $4 a gallon like Europe, then this will start to be worth it.If its about not paying for foreign oil then give it a shot.

Its not all about saving money, it has lower emmissions and, Do you know what the term peak oil means? I'd rather start now than become more dependent to on gas when the decline comes. There also would be a jump in power. The blend is 85% ethenol and 15 % gas this makes a total air feul ratio (according to your stats) around 10:1. The ethenol industry has been working on this gas for a while. They are determined that the benifits far out weigh the drawbacks.

nope. no idea. Whats it mean?

 

peak oil is a term that reffers to the worlds oil production. We have passed the "peak oil" already. This means gas prices will only steadily get higher nad the demand will not decrease. The goverment will keep a reserve for themselves and us poor consumers will be driven into panic while the gas supply dwindles.

i'm afraid not sir, You could however problby get by with runnign it leaner so it would get better a/f ratio than stoich since it's harder to make it detonate then regular gasoline. Unless you adjust something in your engine to take advantage of the higher octane you wont' get any more power.

 

Jesus man!! thats what this thread is about. With e85 i would need a hondata like device and maybe some new feul hardware to even try and run this on my car. I probibly also need a very large spark with it so some aftermarket ignition will need to be used. I am not talking about running a bone stock b18a on e85. Thats impossible. With this proper tuning and equipment i would reach a higher power than with pump gas. ethenol= more efficiant combustion=higher octane. Think about all the other ffv's out there. they can run on e85 because, most likey, they have an advanced computer that can sense the different characteristics, and adjust the engine acordingly.

 

Any more answers out there?

Simply converting a b18 to run on e85 wont' increase performance, higher boost, compression, will

 

True, but i want to convert to e85 and i will be tuning it to run on it for max peformance
News Update
In the news it is a big story that they will now begin converting racecars to start using e85. apparently the engineers found a very good way of doing it.

Actually, ethanol DOES give you more power. The reason? Despite the fact that it's heat of combustion is lower, the increased amount that you can burn with a given amount of oxygen (which is fixed in an engine of a given displacement) more than compensates for this.

Dohh!!! i was just thinking about the octane of the fuel I'm soo dumb sometimes.
