Interest in e85

Hey guys, was just wondering how many of you would be interested in an e85 conversion? This mostly goes for the M3, but its possible withe non-ms as well. Conversion would include a new flash and injectors. I imagine gains would be somewhere around 25-30 hp for vars without a flash, and around 10-15whp for those with a pre-existing setup. You have to remember this is a fairly prrmanent mod. Once flashed the car will only run on e85 until flashed back to a 93 file.

Let me know what you guys think

I'm running it on my 330Ci with a flex fuel sensor. There were definitely torque gains, but they would have been better on an M3 with the higher compression.

The stock non-M fuel pump will be marginal with E85 flow rates.
