new update. I've done a lot and ruled out a lot.
What I did:
N75 testing and replacement. All was fine, good resistance. no change in symptoms.
new plugs. old ones were fine. Missfires reduced? time will tell. Old plugs had signs of moisture reaction, red residue on the ceramic.
Tuned eDV properly. Read FR on it's control, understand it, it is working as it should. It's not associated with the boost fluctuation.
Swapped in new maf. PNG associated. Maf isn't the issue.
Next is O2, need to find one first...
I keep getting an implausible signal from my vehicle speed sensor, often. Have to replace that, might be the issue.
On to fueling. Log attached.
4bar FPR, KRKTE scaled. High flow fuel pump as previously stated.
IDC is still hitting 100%. not 120% like it was before though. I need to read up on how to properly numb BTS so I can make that dissapear and actually get a good look at my IDC during open loop.
Pointers?

Why don't you log the LAMKO variables and isolate exactly what is requesting that enrichment?
ATR, BTS...?
What does timing look like? Ignition angle efficiency?

His IDC is > 95%, RKTi kicks in by the looks then maybe ATR and or injectors (h/w) or cals as it's way below lower lambda limit. |

IDC is still too high. |

ATR, BTS...? Because I don't quite fully grasp how ATR and BTS affect LAMFA. Looked at German FR. Lamfa_w? Lambts_w? dlamatr_w? Lamnswl_w? lamkh_w? flamkh? lamdkt_w? lamlash_w? lamelsh_w lamka_w? lamlshv_w? Lamau_w? they also have "2" derivatives…should I log those? This is a tidbit confusing…I have studying to do but not sure what to study to fully grasp the subject of EGT enrichment… made this pdf from the FR. study this? or is this not the full picture of the situation? |

Well EGT enrichment comes via ATR lol, dlamatr_w is the delta value.

I'm not sure you understand RKTI. |

Lamfa_w?
Lambts_w?
dlamatr_w?
Lamnswl_w?
lamkh_w?
flamkh?
lamdkt_w?
lamlash_w?
lamelsh_w
lamka_w?
lamlshv_w?
Lamau_w?

Most likely lambts_w and dlamatr_w will be enough. |

Logged those two variables. I studied the wiki on fueling again. Makes more sense now. Interpreted a bit of the FR. The puzzles pieces are beginning to fit together.
Dlamatr_w is 0 all the way. Fueling dip looks to follow BTS. Ill dissable it later and log.
I think i need to log lamfawkr_w too.
Thats for the rundown phila

Forgot that one. Ill add that to the pile along with timing efficiency stuff.
Ive been sort of interpretting where tabgbts comes in, forgot i can log it.

Disabling shouldn't be the goal here.
You want to find out what is requesting the enrichment and why.
Again, what does timing look like?
Heavy retard can trigger enrichment through lamfa_w and late angles can trigger enrichment through lambts_w.
As SB_GLI is alluding to, tabgbts_w (tabgm_w on 551M) can be triggering a multiplier to lambts_w.

you understand RKTI.
look again man it in the efin diagram and asm! It's YOU that don't understand it! One way thinking - I'm surprised. For the correctness of the thread you should consider retracting that incorrect statement as it derails pages pack lol I have no hard feeling just surprise!  (I'll give you a clue one of the maps begins with a P) |

99% ATR but he won't listen or log it or even disable it temp. I'm done deaf ears n that. |
