Log voltage at your O2 sensor and see what it reports at rich.
Also, a curious thing to note that OEM BMW used a straight LSU4.9, where a diesel specific LSU4.9D is more appropriate, resistant to soot and works quite well. Bosch part number 17466 |

I had questioned whether soot may have an impact on the O2 sensor myself. Unfortunately, I do not have any pre-delete and tune logs to compare. I was unable to find the spec sheet on the 17466. I could not find where it benefits a diesel application. Are you currently using the Bosch part? |

I actually should correct myself. Wideband O2 Sensors do not do voltage, they are actually current based and each manufacturer has their own way of doing this.
This may be useful: I was able to do some logging in Carly parameters and comparing to my old O2 sensor my new one does not dip down as far. For example, at idle on our cars, you should be getting 0.85, at zero throttle coasting 1.23 and full throttle 0.59. My old one was dipping to 0.19 that too me was reporting too rich and result in DDE corrections to defuel. These are just my brief observations and my not be correct. Replacing the O2 sensor is not difficult and took me an hour, but resulted in a significant driveability improvement so far. Given that their life expectancy is about 120k Miles, some of us may be getting into that range. Mine was $129 with shipping and I did it on a hot manifold so it breaks loose easier. These may be useful too: bosch-4.9d.pdf LSU49_D.pdF |

Foodstamps 14.66 afr constant? I'm not sure what afr is smoky on our diesels. On the tdi with less injection pressure, 14.6 would be like a James Bond smoke screen lol |

16 is clean, Iirc on my tdi 16.5 was barely a haze
Does the 35d have a diagnostic for injector balance like the vw TDI has? Also what is the peak rail pressure? Tdiwyse found that at a certain level the cp3 ip relief valve drops pressure. But because it was on a running box which lies about rail pressure, we couldn't see the real limit but it's probably a bit above 1800 bar. On torque running less pids, inputs gives better sample time for each reading. Some pids are based on the same reading, as duplicates they don't count (like my crazy maf ones, lol) |

You will be searching for a table that contains results with OBD in the name.
Reference the Excel sheet I provided earlier in the thread. That should give you an idea of what you might find. I only support the 335d, but good luck! |

i have a 435d which i think is the same engine what is confusing me is fuel rail pressure sensor isnt working on Torque Pro but is on Dash Commander. also on torque my boost is maxing out at 22.5 psi is that normal

Torque and the PID spreadsheet mine shows 24.5psi max on a highway run to 80mph. did a 0-50 mph run and i only had 20psi max in the lower gears. In 1st or 2nd it only showed 10-15psi. did clime to 20psi until it shifted. since I was in D not sure if it was 2nd or 3rd gear when it made it to 20psi. I find it weird that car doesn't make higher boost in the 0-30 mph range |

Ok - I've created the custom PID's in the torque App during a 3 hour long meeting this morning....
I'll test these on the way home tonight. |

Hand entering the equations enables lots of opportunities to miss the exact operator precedence (things like "(" or ")"). If things aren't exactly correct, it's very likely they won't give a result.
