open loop. so my bike has NO O2
the same map i run with. MO2X, E10, Red X 112, and 91 pump piss.
so if there is no O2, then no corrections can be made correct? if it doesnt know what AFR's then corrects CANT be made to the fuel table. even if i made a video of my bike running with my commander pluged in you still would say that im wrong. when i get my stand alone wide band. ill hook that up to the screen and video what fuel i put in it. and show you what it idles at. that way you can call all the bullshit that you want and still be wrong. so i would like for you to put in your own words explain how its wrong.

the alcohol engine will use MORE fuel per revolution, BUT you will get MORE HP, also the torque curve is flatter
as was said the alcohol engine will run cooler than its gasoline counterpart which means you can shove a smaller radiator in a car which means you can have a smaller frontal area on your car which adds to the Aero which aids MPG due to the fact one needs LESS throttle opening to cruise or accelerate to/at a given speed.
also because you are making more HP and the torque curve is flatter you can use that one revolution to go a FARTHER distance, (via correct gearing for power produced) this also translates to a better MPG than what you may calculate if you only looked at Stoichiometric fuel mixture volume and ignored all else... remember, gallon for gallon alcohol has less energy, but at stoichometric their is more energy, this translates to more power per time/rev, the relationship of how much more and the volume used needs to be weighed with its benifites when used toward a MPG goal...
of corse if you make more hp with a given CI you could rather than gear the car, you could make the engine smaller and keep the same HP, and benifit from reduced weight, would it be worth it.... after all, one must think in terms of the OEM's if one is to banish a fuel source....
does this mean that an alcohol engine can get as good of MPG if alcohol was used in a car NOT designed to be used on gasoline? I doubt it, but I never did a specific test, nor do i have the time for such a test at the moment. the problem is with most of us is that we are trying to get a gas engine to burn alcohol, this is already a big crutch because alcohol engines can take advantages of using higher compression, one of which is efficiency.....

i understood everything i read that you wrote, but i didnt read all the posts before mine...
I also was talking about 100% alcohol not E10, thats where you can see the differences well between the two fuels.. I encurage every1 here to experiment for themselfs how well an engine runs on alcohol. if you have an OLD small gas engine like an old Wisconsin, Kohler or old Briggs with an adjustable Main jet, turn it out 2 full turns and turn your idle screw out 2 turns and give it a try.... what you will have is an engine running on alcohol. one that was not designed for it, and thus lacks the efficiency it has with gasoline, but add compression and tweak the cam and ignition timing and you will have an animal...
lol whats next, an argument on biodiesel or vegi oil VS regular diesel and how it (biodiesel) makes more hp??

Here's a new question, why make gasoline that "contains at least 10% ethanol" if it doesn't bring the freaking price down? I'm paying $3.82 at the pump for lower quality gasoline, if it were a dollar cheaper I would be less inclined to complain.

Ethanol would not be used in our fuel at all if not for government mandates requiring it's use. It may be around as a niche fuel in farming areas, but no where else. It cannot succeed in the free marketplace without those government subsidies and mandates forcing it's use. Only E10 can be sold in southeastern Wisconsin. Up in Green Bay, it is not required yet but government subsidies encourage it's use even where it is not required. I can still find 100% gasoline at stations here, and that is what I use when I have a choice.
As for the reasons why ethanol has been forced down the US consumers throats, see MARKGB's UNIVERSAL TRUTH NUMBER 1.
