Ok, the Buzzken exhaust and tuned ECU are installed. Now I'm seeing a CEL. Using Bimmerlink, the codes are as follows:https://photos.app.goo.gl/FKAsrKn86XCqnHWb9

I was under the impression that the ECU tune was going to turn off these sensors. Am I missing something here?

Correct, the tune should have taken care of that.

I've emailed AARodriquez with the codes, so we'll see what comes of it.

Yes, tune should have eliminated those. Did you clear the fault codes and these came back again?

Did you plug it into the right temp sensor?

Yes, multiple times using BimmerLink. The CELs will go away until the next power cycle of the ignition.

This is an interesting question. Iíve used my magical mobile-photoshop abilities to illustrate my current sensor/plug configuration.

Pic of current situation: https://photos.app.goo.gl/wuD83LGSFSDQY42D9

Colors are from left to right:
- White = open; was sensor connector from middle of DPF
- Blue = connected to current O2 sensor
- Green = open; was connector for DPF
- Yellow = connected to current EGT probe
- Red = didnít touch it; remained connected

Input is welcome, as always.

But the codes are for the Particulate Matter sensor.
What did you do with that?

The Buzzken down pipe only has two bungs, one for O2 sensor and one for EGT probe. All other sensors/probes were removed with factory DPF. My first pic above shows this at the bottom.

Just checked, your setup looks correct. The white connector plug and rearmost plugs are disconnected. Thin wire EGT and O2 are transferred over.

2014 328D rwd with Mission Performance stage 2 tune and Buzzken DP and mid installed. Removed all unnecessary sensors, modules, and the def tank. done on 12/14/18 after flashing codes P2047 and P20BD came on after I cycled the ignition. I can clear them and they will stay off till ignition is cycled again. Waiting to hear back from Mission Performance. Other than that really enjoy the tune. With the oe muffler its sounds stock inside the car while driving, when you stab the gas with the windows down you can now hear the turbo and a nice low tone. Wish the Buzzken had better instructions or something beside 3 B/W pictures that aren't legible lol

So I'm really on the fence about this. I have a piggy back that is a pretty solid bump in performance. But if I do too much, I get limp mode. I don't care about CEL's as long as I know it's not a real problem/issue. But one thing that I will say of concern is soot. At WOT I don't really care how much coal I roll. But under normal conditions, how much soot do you see?



Like my chipped 6.0L Powerstroke. Under normal acceleration and driving, it doesn't produce much of anything for smoke. When I hit the skinny stick, it will just about black out the sun.



I really like the numbers they are posting for the improvements...I believe it's higher than what I currently get when I turn my chip up, which is night and day difference over stock...(BMW screwed up with the existing OEM power.)

If you are on a chip then you still have your dpf. If you are rolling coal now then I pity your dpf, regens, and clogging.
