2009 335i, 78k miles. First time taking a log in this car, didn't really get a full pull but hopefully it will do. Trying to figure out where these codes are stemming from & what its effect on my car is. Currently on map 0.

Can post some more normal driving logs if that's preferred. Also, is it possible to get stft/trim on both banks using jb4?

My best guess is the precat oxygen sensors are bad, previous owner ran a lot of E85 if that matters. I'm running straight 93 nowadays and on a stock backend flash. Car is FBO with downpipes but never had this problem until now.

Or boost/vacuum leak? I'm new to reading these logs but it does seem to be running kinda lean under boost, but nothing crazy. I did have the intake manifold pulled up enough to do the alternator recently and the codes showed up shortly after. Trims also seem okay from what I cant tell.

Also, having trouble with the JB4 program a little bit... For some reason I'm not getting any values on AFR2. And I also cannot get 6-cyl logging even though I have it set to "5" for IJE0S.

Replaced precat o2s and cleared codes. Have driven probably 20 miles and no codes have come back yet. Couldn't clear them for shit before.

I also put my stock downpipes back on but for other reasons. Same post cat sensors though
