I have seen a gm comercial on tv talking about ethinal fuel made from corn and how it would be  a renewable fuel source . I have also see on the discovery channel that in brazil this is standerd practice already and is also law that if you sell gas you must also offer ethinal . My concern is on both thier was talk that gm has equiped thier engine managment systems to measure the oxygen levels in the burned fuel to tell the ecm how to adjust timing of the ignition and the fuel injection to compensate for this or any combination of fuel to ethinal mix . If this becomes main stream are there conversion available for this or are our jeeps with oem processors compatable allready ????  

Its a little more complicated than an ECU swap  

Right still WHEN JETING A CARBURATED SPORT BIKE FOR ALCOHOL THE GENERAL RULE IS TO INCREASE THE JETS BY 5 TIMES WITH NO ECM CHANCE AT ALL THE ONLY REASON THE ECM IS EVEN AN ISSUE IS DUE TO THE FUEL INJECTION .

Running a 10% ethanol blend would require no modifications, but the 85% blend would. Ford products that can run this blend have a sensor in the fule line to measure the blend and adjust the computer accordingly. Converting another vehicle would involve replacing all the fuel lines and seals, possible the fuel tank as stainless steel would be required, adding a sensor to measure the ethanol content and a computer designed to do this. On a carb setup, you would have to set the vehicle up for one fuel or the other. The computerized versions would automatically adjust for whatever blen is in the tank.  

assuming all the plastic is up to snuff, I supose you could have a fuel oxegen sensor hooked to a fuel pressure regulator.  that would be about the simplest way
 

Ijust think its is an area of concern for us . Being ready is always a good idea .it does look like it is a coming revelution.  

actually this has been around for awhile or at least the %10 stuff. buti dont like it cause its more expensive (kansas to oklaman that is) and doesnt seam to have as much power, but it does seam alot cleaner.

but dont they use the more potent stuff for racing?

lol i was jsut thinking iv we put ever clear(grain alchool) into our cars at $8 for a 20oz bottol, then gas at $2.05 a gallon doesnt seem that bad  

I was doing some research last night  there are a few they are called Flex Fuel Vehicles on the market and have been since 2003 it looks like the Chrysler mini vans that are engine donors for the 07 J(un)k Wrangler are of this type and are capable of using E85 (it's called because it is 85 % ethenal 15 % gas), but I have found nothing about retro fitting or if any excisting jeep are compliant.

   I did find plenty of info on biodesiel from kits to make it how to find it. And considering in florida the only two places that have E85 are commercial and do not sell to the public . Any body gotta diesel liberty motor to be a donor for my wrangler and diesel makes more power and is less explosive!!!!

We just got a station here in Michigan that sells ethenal.  It sells both the regular 10% stuff, E85, and bio diesel on every pump.  The regular stuff is 89 octane, and is competitively priced with 87 octane around town.  the e85 is MUCH cheaper, but is 105 octane.  Everything I own runs on the 89 octane gas from my '80 Chevy with the '72 307, to the 2001 Silverado, or the Comanches.  I only buy from there if possible, supporting the cause, and running a little cleaner burning car.

Yes, you could argue power loss, but with any higher octane fuel, such as racing fuel, a higher compression produces the hotter burn needed. 

I am totally on the ethenal bandwagon.  As I understand it, ethenal (actually having been around for a long time) is basically high power corn whiskey (moonshine).  it is produced from vegitation, like grain and corn.  This is what interests me, because it's a clean burning fuel that is produced from farm produce.  Around here in farm country, that's good news because if it takes off farm land will be worth something again, and farmers make a living again NOT to mention we are no longer under the strangle hold of the Arabs.

even if the fuel we use requires 15% petrolium, I'm sure this country can drill up that much gas.

As I understand it, the open wheel race cars- Indy series I think, I read that whole series switched over to ethenal

Thank you all for the insights on fuel sensors and how the variable fuel cars work..  I'm still researching it myself; the Scrambler is going to be VERY green friendly...  as is everything I own in time.

my 2+ cents.

Does this mean that I should start making Moonshine to put into my gastank?  

it worked for the General Lee  

Well it does seem we have definitly found a cause now if I could just find some in Florida to try in my YJ. I would very much like to see a rebirth of America . The government pays farmers not to grow corn to keep the price up. What would happen if thoughs funds were rerouted to an investment in this future. And oils were used us lubes istead of fuels.corn grows back right and arabs can't profit if we don,t let them considering 91% of the worlds fuel is used in America.If this is effective the world terrorism cash flow would be disrupted as well . thats would be two birds one stone right.    

or jsut sell it, and use that money for gas, or do what i do

go to a vacant house and ripe the copper out of the wall, strip it, then take it to salvage, $1.65 a pound

and gas just went up again here 10 cent in 24 hours
