That was a fun project, still trying to find a tune though

Wow resurrected from the dead.....sorry havent had time to get to this since all the new parts and RnD with the C7 Z06. We will have all the stuff ready to go beginning of next week for the C7 and C7 z06 plug and play. We can handle mail order tunes (email) and bench top tuning as well.
This is an integral part of the C7 z06 running in the 9s on our shop car.
Please check out our youtube channel fasterproms.
Thank you
Jeremy

I echo RonC7's reply above. Ethanol is more corrosive to engine components if these components are not designed for E85 fuel. Secondly, JJFORMATO's initial post is in error in several aspects. E85 is 15% ethanol, not 85% ethanol. Also, ethanol fuels burn at a hotter temperature, not a cooler temperature, which can destroy engine components not designed for E85 fuel; this is a major problem with outboard boat engines and motorcycle engines and the reason AMA is lobbying strongly against E85 fuel at this time. Finally, the more ethanol you have in your fuel, the more moisture (water) will accumulate in the fuel out of the air (alcohol is hydrophilic)--not good for engine components if your car sits for a while like many of the Vettes do during the winter months. As a sidelight, I run non-ethanol fuel in my household engines such as lawnmowers, weed trimmers, etc. so that the above problems do not occur, and the non-ethanol fuel will not destroy the rubber tubing used to move fuel from the gas tank to the carburetor (rubber tubing disintegration causes small rubber particles to clog the carburetor jets).

1. E85 contains 15% ethanol
Try this: E85, what is it?
2. E85 runs hotter combustion temps
E85: Cooler or Hotter?

Not true. E85 is ~85% ethanol and ~15% gasoline.

Can you post a picture of what your E85 conversion looks like installed? For a mail order tune can you supply an EFILive file or do you use HP Tuners?

DOCLEX: You are very misinformed on almost all counts. About the only thing you got right was Ethanol and some types of rubber don't work well together.
FYI; E85 is usually a little less than 85% in ethanol content but not @15%
From the dept of energy
Most of the gasoline now sold contains some ethanol, but the exact amount varies by region. In general, the ethanol content does not exceed 10% by volume. Gasoline with 10% ethanol content is referred to as E10 and with 15% ethanol as E15. E85 means there is 85% ethanol and 15% gasoline. Most of the gasoline with more than 10% ethanol is sold in the Midwest.
All gasoline vehicles can use E10. Currently only light-duty vehicles with a model year 2001 or greater can use E15. Only "flex-fuel" vehicles can use gasoline with an ethanol content greater than E15.

Sorry about that
I thought I had recanted my post, but it has not appeared. My mind was in the E10 vs E15 mode. Still a problem with the hydrophilic properties of alcohol particularly in tank of a hibernating Vette in winter months, and other multiple differences in fuel/engine components between FFV and non-FFV. I don't know the characteristics of Vette fuel tanks, fuel pumps, and fuel lines wrt material used and ethanol compatibility to assess. Since I'm not tracking in a competitive mode, I won't being messing with E85, and hopefully not E15

I ran E85 in my LS3 corvette for 3 years and logged over 40K miles. Not one issue ever, and when I checked the sparkplugs after 35k miles, they looked so clean I could have said they just came out of the box.
I'm so used to all the people saying "it's going to melt your car". I simply and kindly reply, these are all myths.
E85 is actually MUCH better for your car than gasoline. I'm not going to go into depth however, I can say that I have done my research, and I also have real world experience, and i'm not some keyboard warrior passing along incorrect information. Corvettes are mostly made of truck parts, which from factory support Flex Fuel. These cars run fantastic on the gold fuel.

I'm in the ethanol production industry so I try and stay out of these since undoubtedly someone calls be biased or speaking with motive, but I do agree with everything you're saying.
