2013 BMW 335is DCT
RB GF 17T TD04 turbos
Inlets/Outlets
DP's + 3.5" Exhaust
BMP Stage 3 LPFP with BMP Port Injection
Full E85
XHP Stage 3
CTS IC, etc, etc, etc
Maintenance:
Index 12's
OEM HPFP
RB PCV
OEM valve cover
4 Bosch Oxygen Sensors
NGK 2-step @ .020" with PR coils
I have misfire detection turned off from 6000+ RPM just to figure out why my car still triggers a misfire on Cylinder 6 and some times Cylinder 5 & 6 at the same time. I noticed bank 2 STFT pegs out around -30 in the mid range and picked up towards the higher RPM. I'm also on the process of having my HPFP swapped by FCP Euro because I made a thread last week on my rail pressure randomly dipping and based on Precision Raceworks opinion they suggested that I replace the HPFP. I attached a photo of a screenshot and I noticed at 6,666 rpm the AFR on Bank 2 is lean, but I can't tell if that's after the misfire or before the misfire because the rail pressure is still reading above 2000 psi and the throttle is still at 81.
