Exclamation Help N55 E series - 09-21-2017, 04:31 PM

I got the jb4 used about 2 weeks ago and feel like it's not running right. I got a 2013 135i N55 and fuel is around 70% E91 and 30% E85. Have a aftermarket FMIC, Chargepipe, Catted **, and had/have Dinan tune installed prior to this. Sorry I don't have the photo logs. I noticed the throttle also goes up and down on the photo logs. Here are my logs of map 2 and 6 + settings:

You'll have to get the code description and use that to diagnose what is wrong with the car. It's not in my N55 code listing, maybe a valvetronic issue based on the first 3 digits? Could be an O2 sensor also as the AFR reading is stuck in open loop.

I am pretty sure both codes are part of my sensors on the down pipe since it's not stock. But I wanted to know if my logs look alright and why it loses boost sometimes.

The logs look bad, due to AFR being stuck in open loop, which I suspect is the result of the code. It's not a normal code so needs to be addressed.

The problem with my last logs were a broken O2 sensor which I switched out this week. Can anyone look at my new logs and tell me what is wrong? I get multiple misfires especially in cylinder 5. I also have about 40% E85 mixed with 91 gas, maybe that wasn't such a great idea to do? Thanks in advance!

Running an old board with newer ISO firmware, I'm assuming the diode on the board has been cut?

If cylinder 5 is consistent...I'd recommend starting there.

Also running pretty rich, probably due to the Dinan tune but that is also causing your HPFP pressures to drop.

I fixed the problem by changing spark plug #5. I did another log in Map 1 and wanted to see what you guys think, if it looks okay since boost is a little above target. Thanks!

You never confirmed if your diode is cut.

Timing is not good.

A little overboost but not too bad. FF will probably learn down a bit but if the issue continues, may need to do some DB tuning.
