Today I did a pull and felt some misfire like hesitation up top. Luckily I was able to get a log of the event.

This was on my pump gas map. I have a e92 335xi with a 6AT. My setup for the last two years is frankenturbos, overdriven hpfp, fuel stage 2+ lpfp, cp methanol.

anyone know what can cause these types of codes? Spark plugs are brand new and Delphi coils are now 5 years old and under 38k miles.

Thanks for taking a look!

Possibly engine mounts. I’m also 335xi AT (FBO stock turbos) and had seen lots of timing pulls like you did on a few cylinders. My original right engine mount was shot (damn exhaust heat) after 70K miles and after replacing it my timing corrections have been substantially reduced.
