Ok, so I did a lot of reading, read most of the posts of dzenno and seems I'm having the same problems he used to have (misfiring up top of the upgraded turbo during WOTs).
At first he started looking into hardware problems, changed most of the parts that possibly caused misfires. Then, with no good luck, he decided to go with Cobb AP and to turn of misfire detection as his thoughts were: Quote:

And then BAM: Quote:
Can someone explain what injector coding is?

Thanks, I already found the vid and thread an hour ago But I still don't get it...
What are the reasons of bad coding? How do I know if my infectors are coded improperly? Do I have to do it myself or can I just tell bmw ealership to check if the injectors are coded properly?

Well, I am trying to head towards sorting out the reason of the misfires ))
And I wish I didn't have to chose the Cobb + PROcede solution.

Talked to a friend of mine who works at bmw dealership. Explained the situation. I'm taking my car to the dealership for injector coding check today or tomorrow.
He aslo had a few other ideas regarding the problem, they will check. They will also try to swap the injectors in places to see if it wasn't injectors fault itself.

I suspect injectors and or coils. Did not read the whole thread so if you have replaced your coils I would definitly check your injectors.
Have been running for more then 30.000km with RB's and Rev 2.5. No software related missfires like many others. Offcourse an combination of factors could cause this but in many cases: plugs, coils and injector related. I remember that you also had 29cc code, this could be LPFP related.

Edo- before getting too deep into anything, I would suggest updating to a rev2.5 as it has updated ignition circuitry that may solve (or at least reduce the frequency) of your high boost misfire issue. You will also be able to run the aggressive maps which are unquestionably better than the old maps you are running now. If the problem still persists, then the cause is likely a hardware issue as others are suggesting.

Thank you, Robert contacted me already.
Next time I'll call, but there's 10 hour time difference...

Took my car to bmw dealership today. They checked injector coding - everything was fine. I asked them to swap injectors 5, 6 with 1, 2.
Will see if the misfires occur in same cylinders as before. I will receive my Rev2.5 next week. Hope it solves the problem...
