I know that alot of people have considered/done the E85 tune, and have got impressive results. My question is, is there a way that I can run a flex fuel type setup, where I could go back, and forth between E85, and 93 octane. The only reason I am interested in doing this, is the current lack of E85 fuel stations in the US, (only a little over 1900 currently)

 

Im sure vince could come up with something with his switch tunes? being your a lsj, not sure if he has done that feature yet for you guys.

 

switiching tunes may work but a true flex fuel car senses percent ethanol in the tank and adjusts stoich for it.
