Title: e85 104-110 Octane Chip
Post by: RIPDOTCOM on December 06, 2007, 07:59:14 AM
I have been running a 50%+ E85 mix in my Turbo M20 for over a year with fantastic results. I know d'sylva makes a 93 octane chip for the M42 but was thinking about trying to get a gb together for an E85 chip. Ethanol has an octane rating of 104-110+ depending on the season (they lower the rating to 104 in the winter). This stuff is basically race gas and is readily available for less than the cost of 87 fuel. Hell, we even have a station in Tallahassee, FL. Also, contrary to popular belief it does not eat through lines and tanks etc... There was a lot of that misinformation floating around but it is false. Anyway, share your thoughts and see what we can do. i am ready to roll with cash in hand :)

that's really interesting, i wish we had e85 here in Montreal.
onces you've put the e85 chip could you still use lower octane non-ethanol fuel?
i'm not familiar with ethanol fuels but here in this video it seems like it's a major change from petrol

i think megasquirt with dual maps would be a better and easier way to do this.

There was not enough interest.  I'd need at least 15 cars and a test car here in Toronto to do this.  Or I could tune it remotely if someone had the Innovate LM1 and rpm logging capability.

I think megasquirt with a fuel composition sensor to scale your reqfuel is a better way to do this
