    Cylinder misfire help, data log included

    Under load at 3000rpm. Can hear and feel misfire. Restart engine and it goes away. Running COBB stage 2 tune. 40k miles on 2009 135i. I’ve ordered plugs. Could it be the coil pack also? Timing from data log suggests huge swing from advance to retard at misfire point. IPW is consistent at 45-50%

    Those cars, when tuned, love to eat coil packs and spark plugs. That's where I would look first.
    Swap some around to see if it moves along with it.

    New Bosch coil seemed to remedy. I’m going to pull a log to see. Y
