In case you're interested these were my results from playing with E85 on stock hardware. Results not corrected for elevation. My custom E85 map is fairly similar to the E30 OTS map but fuel is adjusted for a higher E85 content. I found the E30 map to be a bit too aggressive in timing for my tastes on only 30ish % E85.
