Attached log of cold start. Looks like HPFP is shot even though it’s brand new?
LPFP stays pinned at 84 because z4 has no sensor

Anybody? Should I swap my old HPFP back in?

EDIT** found a crushed vacuum line but I’ve replaced it and same problem. I believe it to be a JB4 setting issue? I followed the hybrid turbo setup exactly. I was messing around with FOL lowered it from 40-30 and the fan quieted down for a few seconds and then went right back to full blast. Car is still in limp mode with 29F2 and 2AAE shadow codes read via MHD. I don’t have any codes read through JB4 mobile.
