    Default Why so much spark advance?

    This is a short log I took yesterday while cruising. I do have some turbo blue in the tank would that have anything to do with it? I just got efilive yesterday so I havnt changed the tune yet. Only mods are long tubes, ory, catback and a lid.

    You're not boosted, so timing looks ok...

    at light load the PCM commands higher timing;
    when load increases PCM commands lower timing;

    and you got zero KR.
