Exclamation Dct M4 Flywheel Installation - 09-01-2018, 02:47 PM

Guys, my car has been plagued by an issue ever since my M4 flywheel went in, well there's certainly been other bumps in the road but I'm pretty certain the latest coincided with my flywheel replacement.
My question is can the swap been done incorrectly??
It seems like maybe my crank angle sensor is involved with the issue.
I dont have my original fw it was binned by the installerand the car is in a different shop now.

Cheers!

Weird codes that dont make sense, ecu fueling and knock but logs show all is fine and the car isn't actually knocking.
We have now swapped the crank angle sensor and the problem is actually worse. I think it's open circuit code (but it isn't open circuit and the wiring harness looks fine. I'm the Aussie dude who emailed you, we decided to push my car off a cliff lol!

I installed the Mfactory flywheel on my n55 last week. I used to experience the random misfires at high rpm before installing the flywheel. Since I've installed the flywheel, my car has been misfiring a lot earlier (around 4500rpm) at any boost level past 22psi. I've also been experiencing drastic timing drops, not sure what's causing that. I'm not sure if the flywheel is to blame for all this but my car was definitely in a better position before the flywheel swap. I am running a gtx35 turbo.
