    No none of that has been apart. First thing the tuner suggested. He said a crank relearn, which I assumed he meant neutral profile relearn.

    Yeah not sure what to do. I heard I can do it with an X3, but I updated it and it still doesn't have the neutral profile relearn available.

    Does the tuner have to be married to the car? Tim from Rodeheavers said I just have to return it to stock first.

    Logs show bank 2 sensor all over the place. Looks like it could be what I originally thought it was.

    Relocated both O2s (thanks Greco!) and replaced with new from dealer. Car runs perfectly. Much better than it ran when I first changed to E85, have a feeling they were going bad before the change.

    Glad to hear you got it figured out. What could have caused the O2 sensors to go bad. Isn't the car basically still new?

    The way they are positioned in the headers I have, condensation collects in them and causes them to fail prematurely. E85 just sped up the process. Car has just inder 4k miles.

    I see what you're saying - just surprises me that could happen after so few miles. The headers went on a few months ago right?

    Still have stock headers? It isn't an E85 issue, it's a long tube header issue. Drivers side sensor pointed upwards, condensation gets inside and kills sensor. People kill them on gas too.

    Kooks on the fox. Sensors point up and in towards trans. Picked up half a second in the quarter with e85 and 300 pounds out of the car.
