Default Re: rich condition and fuel pressure help

I believe the injectors are the 36 lb that supposedly come with the kit, they would only have 20k miles on them when the kit was installed:


The FPR looks pretty old, so I assume it's stock. I have a scan tool to read live data and that's how i got my STFT and LTFT readings, which indicate the rich condition.

I thought 51 psi (3.5 bar) with vacuum line off FPR is where pressure is supposed to be, at least that's where it is with car running.

Unfortunately don't have INPA but could probably download it. Is there version or link out there recommended? My brother just bought a cable to code his 135i so I can probably use that.
