    adjusting E85 mixture

    Changing this Trackhawks fuel mixture has me stumped. My V is a piece of cake matter of fact everything about tuning this is a bit of a pain. If I want to make it a little leaner is there one spot to do that?
    Thanks

    You'd need to adjust your PE table. What are you targeting for lambda?

    I'm thinking .80 my tuners done a great job but i'm at .84 most spots. I should just be happy but I have a hard time leaving well enough alone.
    Thanks

    Seems a little lean for a boosted heavy ethanol setup. Any chance it's on a dyno?
