Anyone know of an XJ that has been converted to take E85? My crown Vic for work is a flexfuel car. Yesterday I filled it up with E85 at $2.00 per gallon. Regular gas is $2.80-89 I don't remember. I did the math there at the gas station and I would have saved almost just over $10 on that fill up alone....
I thought that when gas shot up over a year ago and flexfuel was just coming out people were saying that all you would need to do to make your current engine flex fuel compatable would be fuel ingectors that would spray more gas. While this might hurt your gas mileage some your gas would be 28% cheaper. I know on my crown vic I don't even notice the difference in gas mileage using e85 to regular.
So does anyone know of a right up on this or know of anyone doing this? Or is there other computer stuff that would need to be done as well?
On a side note I was thinking about buying new fuel injectors anyways sometime in the future, so was thinking that I could just buy the right ones the first time and have the flexibility.
Also for work they recomend to only run 2 tanks of e85 and then one of regular. So not every tank would be e85...

I miss the days that they made toys that could kill a kid.
A guy with a flexfuel suburban/tahoe said he gets the best mpg on half E85 and half gasoline. This was when I worked at the Berger Chevy quicklube.
Of course, that's a different engine and everything.
The swap sounds interesting, just have to make sure the components (fuel pump, lines, o-rings, etc) aren't affected by the alcohol, and the larger injectors.
Running large injectors that'll run well on E85 with gasoline, that won't make our XJs run horribly rich, will it?

It will not work without major modifaction to the ECM (as well as a lot of other componets). Our systems are not designed to run the flex fuel and you will do major damage if you do.
Ya, after some more research I found a few people that had done it. Some had success, but just as many completely destroyed their engines. Makes me wonder if the ones that had success just haven't met the destruction yet.. Oh well, it was just a thought. Thanks for the insite, to those that gave it.

I think a switch to turn off the fuel pump and another to turn on propane would work okay. I've seen a guy with a 'propane dual fuel conversion' kit and the propane 'injector' so to speak was in a hole cut into the air filter lid. I think so long as the mixture is tuned correctly it'd run fine and the ecm wouldn't know the difference so long as its not tied into knowing wether or not the fuel pump is working.
