Default N54 Running lean. - 02-13-2019, 07:19 PM

I am new to the n54 forums. I have a 2008 bmw 335xi running a jb4 with the rev 3 connect kit running map 2, sometimes map 5.

My mods include:
Jb4, Intakes, Arm charge pipe/ Tial bov, 5" FMIC, Exhaust PE mod.

I have had this tune on my car for around 4 months. I recently have noticed that my jb4 has been kicking me into the safety map (Map 4) while running map 2 and 5 under medium boost. I took a few data logs from 3rd gear on map 5. To me it looks as if my car is leaning out, just curious if anyone can help me adjust the values/ has any insight on why I am leaning out. I have a stock fuel system in my vehicle as well. My log is attached.

Attach the JB4 CSV to the post, we don't use datazap.

For starters do an adaption reset, ignition on, engine off, 1/4 in dash a couple times.

Then select map1 and grab another longer log.

Also- after we determine why you are running lean...

You’ll want to enable 6cyl logging & it looks like you are running old firmware too.

Do as terry said first tho

That log is far too short.

2k to redline please.

Also for future- either add the new log to your most recent post/ rely or add it to the intial post & label it.

Thanks
