    New guy tunning question

    I was not logging when this was happening but I have a question.
    What part of the tune should I look at if at a constant Speed/RPM level ground (2k/70MPH) my AFR Swings from rich to lean constantly?

    The answer to your question is TUNING is only speeled with juan EN.

    And BTW your AFR SHOULD swing from rich to lean back and forth in closed loop.
