From the research I've done, when E85 gets more widely available in the Northeast, you may see a winter blend and summer blend. The additional gasoline in the winter blend helps cold start where the E85 may have trouble atomizing the fuel in the bitter cold. This was actually the main reason that Ethanol never really "caught on" years and years ago, and never made it past testing in the "Oil embargo" days.

Flexible tuning or fulltime wideband closed-loop fuel control are the two best options to compensate for changes. I don't know if there are any standalones that are capable of doing closed loop AFR targets (lambda)

I know the setup I have for my Malibu is closed loop all the time, even at WOT..

Then you have the OBD-II legality issues, along with other legal issues as its currently not legal to convert a gasoline car to Flex Fuel..

It begins to feel like they want to dangle the carrot, and then ****** it away as we get closer to accomplishing something.

 

quick question, was this on only E85? or E85 and alcohol?

 

Here ya go

 

^^ e85 only... already been answered..

EDIT: Beat me to it lol..

 

thanks

 

First for david, question about that "flip of a switch" If you were tuning an AEM map, and your "flip of a switch" doesn't change maps, then I am curious how in the hell you could do it since the fuel curves would be completely different. (other than backing off boost of course).

For 9sec9, here in oklahoma, there were 2 pumps that were available for e85 that were just shut down. I have been running e85 mixes for a year and a half on my EVO, and the DSM guys here have been using it longer then that. It is very funny when something so good, takes SO long for people to see the potential.

Since December, those 2 pumps have been shut down and is only available to gov employee's. With this said, there is an E85 plant opening up soon here in OK, and it will be VERY available soon. (6 months at the most). Also, Wal-mart is already selling E-85 at their pumps, I have seen this during my travels. (as well as Sam's club of course).

There are actually 4 grades of E85 listed on many of the E85 FAQ sites. I think these are guidelines for the stations to follow.

It's tough to know exactly what gas is in the stations tank, how long it's been there, etc.

I'll dig up some links later, but basically the only "true" E85 that Ohio will see is during June/July/August. The other months all have varying amounts of gas/ethanol in them. PA is even worse, with the state divided up into two portions, the Northern half only getting "true" E85 for two months I believe, and the Southern half is a mirror image of what Ohio gets.

It should be just a winter and summer blend IMO, but you know damn well no one will drain their tanks just to put the summer blend in, and the pump attendants certainly won't know what is in the tank.

 

Variations in the blend of E85 is very common. A number of 4g63T tuners in Colorado have experienced this, literally from fill-up to fill-up.

 

Guess all of those empty barrels of race gas will come in handy if I decide to swap the pump/meth over to E-85. I'll just fill up one or two of them and bring it back from whereever. MalibuJack, OT, I 'donated' to your site a week or so ago. Good work!

 

David what would you need to run the boost up to 35 or 39 psi
on a built2.3.Would you have to up the injectors ,lines or pump
was the test done with your twin HO pumps.

 

im surprised it hasn't hit the lower warm states yet... temp in fl doens't vary as much as up north.

granted its all made in the midwest which is why all the stations are there. but i think it would be easier for experimental reasons in fl since it never gets hotter than 100 and never colder than 45

cheers!

 

The test was done with standard twin Walbos. I have plenty of pump. To run more boost we need a larger injector. I would not tune this car higher than I have it already.

 

apparently we have a station only 12 miles away

very interesting

 

Thats good to hear Dave, we also have been toying with E85. One of our Customer cars has been running off of it since April 06 and its does really nice and we have had no issues, im sure your Customer will enjoy as ours has enjoyed his. Congrats again

 

Nice work!
