Yes you do have a WB 02 sensor, in the B1S1 position if it is an AWP motor with stock ECU.
Then how come my actual actual only reads down to .75? I'll look into it. As far as logging I almost always use me7. I was just using VCDS to check trims. I logged egt model pre cat and it never got high enough to activate the part protection, I'm pretty sure at least. I need to sit down and go over it all again. |

Are you talking about actual lambda? What do you mean by it only reads down to .75? |

What motor code and ECU box you have? For some reason I thought it was an AWP motor and you were using HN software but looking back through you never said what box or motor code.
Lambda actual doesn't read below .75 but requested Lambda typically falls to around .65 which is considerably richer than I want; check the latest log I posted. AWP is correct, it's in the title of the thread. I'm running an HS tune that is mislabeled as an HN, I just never got around to fixing it. Sorry for not stating that at some point. Anyways, the requested and actual not lining up is what bothers me about tuning the fueling. |

yea saw that after I posted about it. I was never very good at finding Waldo..  I even edited out the comment but you got here first. Add " uulsuv_w " in your ECU file to log. that is " O2 sensor voltage wideband" convert to lambda or afr and I think voila ADD: uncheck the EGT sensor variable, there isn't an EGT sensor and log other parts of the EGT model, even the whole thing if you can. |

I'll add that var. I have since removed EGT sensor; the flat value it showed didn't provide me much information haha. I'll add the other parts of the EGT model Now i'm seeing I-reg adaptation. I can fix that easily though. |

How does one do this? I've looked a few places and cant seem to find a solution that gives me reasonable results. I've attached a log |

I did a little research and I am still looking for what an (ADC-wert) is in the FR. Apparently the output of that variable is the ADC-value of the precat 02 sensor voltage. the actual translation for that var is: "Probe voltage before Kat a broadband lambda probe (ADC value)" So when i find out what an ADC value is, we should be able to use that factor against the data and convert it back over to 0-5v like a normal wideband. I'm wondering if this ADC value converts the wideband signal voltage to short band sensor voltage and that's what is showing on the gragh. I'm not sure yet. your log doesn't have actual AFR only desired, so I can't really compare. I just started looking into this though . |

I'm seeing I adaptation after about a week or so of running a flash. The wiki says:
You can numb positive I-Regulation adaptation via increasing LDEIAP and/or shifting TLDIAPN upwards RPM wise (which you might want to do regardless, if you are running turbos that spool slower than K03s).
When it says increase LDEIAP, does that mean move increase it in a positive manner or increase the magnitude of the number? I.e. it is at -40 stock. Is -50 or -30 an increase?
Also shifting TLDIAPN, does that mean moving all values to the right by a column or two?

I'd be wary of following the wiki to the letter. Best consult the FR and come to your own conclusions...

So the FR reads:
" If the actual limiting value is too small order to correct fully, i.e. (a) deviation > LDEIAP (approx. -20 mbar) ... the actual
limiting value ldimxr is corrected to larger values until the current demand for integration is just met, and the
prescribed safety margin to the integrator limiting value is maintained. "
So, after reading this, I think I should make LDEIAP like -50 or negatively greater. My goal here is to set the value high enough so the deviation won't be greater than LDEIAP, and thus the I-limit will not change over time. Is this the correct assumption?

Lets put it this way: i read the FR and I'm still a little baffled why they are comparing negative values and whether greater than means greater than, or greater than the absolute value of.... I apologize for the vague wording in the wiki but I really didn't want to lead people astray with my bad assumptions. Honestly, it would be best if you could convince somebody like phila or prj to review the actual assembly code  IIRC my LDEIAP is now actually positive; i couldn't get it to do what I wanted to by making it more negative... |

No worries about the wiki. I've set it to -60 and i'll run it for a week or so. But I think i'll have to follow what you did and make it positive. Do you know off the top of your head roughly what you set it to? Is it a bad idea to completely disable the I-reg adaptation? |

+50 maybe?
And no, i don't think disabling entirely is a bad idea, particularly if you are near the MAP limit.
Certainly letting it adapt *up* is a bad idea.

Alright. Right after flash, it peaks and holds about 16.5 psi, which is dandy. But it gradually climbs and today it peaks around 20 and falls to where it should be after a second or so. Upon examining logs, I could see the WGDC was following the raised I value. I'll keep poking around with it and see if i can get it under control. Once i get that under control i think i'll start a new thread about tuning timing and fueling of this bin. |

Wait, hang on, i keep thinking you are running a stage3 s4 if you are well below the MAP limit, i'd let the I adaptation do its thing... but probably disable it while you are finding the right I-limit. |
