It's Official 15% Ethanol At The Pump Now. Whats This Mean As Performance Goes? So was watching the news before school this morning and saw that they passed the law to allow up to 15% of Ethanol to be mixed in with the fuel. Just wondering if this will have any affect on performance, gas mileage or tunes? The old was up to 10% so even tho it's just a increase of 5% just wondering if there will be any good or bad affects to this?
Im still doing my research, but i'm some of you know more about this subject and can chime in.

MPG will go down a bit more. Most tunes will not be affected enough to be worth $$ to redo them, but anything tuned on kill will need it.
I'm sure they'll mix it in a way that doesn't increase octane so we don't get any kind of benefit.

i can see it possibly increasing performance, assuming you are tuned on e15.
you could make more power if you can get more timing in the tune without knock/knock retard
but you will *technically* be required to use MORE fuel to achieve the same power.
so a rescale on your injector pw or fuel tables may be in order to make sure you A/F is still dead nuts, and then see if she can take a little more timing, then double check your a/f with the revised timing table.
thats the theory tho...i literally dont know if 5% increase is enough to mandate any of that tho, maybe someone with some tuning skills can elaborate.

ehh, it wouldnt bother me if the gas actually got cheaper..... but somehow i doubt that will be the case.
same octane, mpg's get worse, pay the same if not more....
so in reality, this green junk will just cost us more.

Considering corn is a basic food stock, and ethanol is going to be more widely used...I can see nothing but a cost increase. Now if they would actually make good on turning compost/leftover plant matter into ethanol, or switch grass, diversify.....maybe, just maybe we could use ethanol as a viable fuel.

Right now it is, and that is still entirely to expensive for alternative fuel, I am just saying that once we start having a higher demand for it (with more and more being used to cut gasoline) we will probably see a rise, rather than drop in price. However corn is heavily subsidized, so I could be wrong.
