MIT study - E85 and FI Motors - Good Read

Cliffs:
Sensitivity to spark timing is diminished with E85
Peak pressure sensitivity to spark timing is about 50% lower
E85 could withstand 265*F IAT and 30*timing before any knock was present (during load)
E85 combustion phasing is about 25% less sensitive to spark timing than gas since it burns FASTER
E85 achieves more volumetric combustion
This is why tuners love it, they have more room for error on a tune before anything bad happens.

It also leads to a false sense of security.
These studies have been around for some time, the question is, how long before the goverment starts to allow Legal Conversion for more then three for four cars. Not that it's enforced or makes any difference at the Smog Station, but hopefully drives more awareness for alternative fuels and the ease of conversions.
