    Blips in timing

    I just started seeing weird timing blips in the log. Seems to be fairly periodic and not related to any driving situation or input. I don't feel anything in the car just see it in the log. The torque adv jumps up for one sample and the main spark advance dips at same time. Checked back in my saved logs and this wasn't happening a month ago when I last logged. Haven't made any recent changes in the tune either, just wanted to check on the summer E-85 blend and make sure all was good. Any ideas what this could be? Log, Tune and Layout attached. Edited my Sig to show car info.
