tuning by turbine color with E85

first look at wheel tuned on E85. This was at 11/1 on gas WB. EGT were low in 750C range. the wideband is new so I am sure its reading correctly. I tried leaning to 12 and beyond but butt dyno felt slower. Now I am thinking it needs even more fuel. maybe 10.5 range.

...are you a stripper? :P.
Yeah that does look a little hot. Although the general consensus is to tune by wideband, I personally like the 70-90mph test and won't go any leaner than 12.0.

Your experience with E85 AFR is contrary to nearly everyone else's experience. Leaner seems to be working better for nearly everyone else.

I dont have the answers. I was just making a friendly observation. I am not so sure that the 12/1 target is ideal. There are some targeting 11/1 with excellent results. This is my first run with E85. I will have better data when car goes back together.

In the 10's the mixture gets hard to light in my experience

MY 02 housing is so clean inside you can eat off of it, and the inside of my manifold has no carbon deposits for the most part, it got cleaned so well that all you see is a bit of surface rust from the iron lol
IMHO I wouldn't rely on the color of the components running E85 naerly as much as I would with gas..

I know running a bunch of alcohol through MY system really cleans things out... whisky $hits FTL

Man, I have to wonder if our local blend is different then what most get or something.
Most people here have better success keeping to the low 11s on E85, 20 PSI or 45 PSI, doesn't seem to matter. Going into the 12s ends in lower power and a detonation prone tune almost every time.

Sounds like its low on alcohol. Par for the course in Utah? :-) Or perhaps really crappy gasoline is used in the blend. Most places blend with 87/88 octane, but maybe they use 85 octane or something.
