    Default Throttle Cracker question

    This is interesting; I am chasing down a slight backfire on shift and i notice that the throttle cracker is active in first, active in third, but bot in second? Take a log at this log and let me know any thoughts?:

    i didn`t see any wideband data, you might want to see if you are
    hitting lean in those spots.
    i got some KR in those high kPa low RPM and had to subtract a little timing.
    also i once had a dirty MAF and it made me run crazy rich, which in turn
    brought on alot of back firing. LOL
