    Default E85 Lambda What are you using?

    I've been using a lambda of .8 for E85 at wot with a supercharged motor. Works great. I just spent a few hours researching and finding that the recommended lambda is somewhat richer. I'm also commanding a maximum of 24 degrees spark advance at wot without any spark timing being pulled.

    What are you using and what have you found to work best?

    I don't use it, but I would suspect you'll find 0.8 to 0.83, or so, is probably most typical for FI applications.

    Bruce - I have mine at .79 which is the same I ran on 93 octane. Have wondered if I could go to .80 or .81. I am only commanding 21.x max spark at WOT on a 9.8:1 motor.
