Ok so lower boost a bit more after 5200 and adjust injectors via KRKTE and TVUB?

dont touch that until you are under 95% IDC everywhere. i can't stress this enough; you cannot do any fuel tuning if you are out of injector. |

I wont. Basically right now were adjusting boost to bring down DC? And by going off WGDC we can determine what parts need to be smoothed out?

IDC is not the same thing as WGDC |

Right. What I was trying to ask is what should I be looking for when getting wgdc under control? Follow the requested boost or sit above it?

Follow boost with minimal swings. |

Here is the latest log with small changes to LDRXN and IRL around 3500-4500.

Still at injector limit. You can probably bring your reqested fuel to 12AFR ish (0.81-0.83) but you should log CF/KR to make sure

Correction factor/knock recognition dwkrz, not sure why you still haven't logged them, they're in the standard aliases, and one of the single most important thing to log for safety. dwkrz_0 , {IgnitionRetardCyl$1} , {zyl.ind. ZW-Sp�tverstellung inkl. Dyn.vorhalt}
dwkrz_1 , {IgnitionRetardCyl$2} , {zyl.ind. ZW-Sp�tverstellung inkl. Dyn.vorhalt}
dwkrz_2 , {IgnitionRetardCyl$3} , {zyl.ind. ZW-Sp�tverstellung inkl. Dyn.vorhalt}
dwkrz_3 , {IgnitionRetardCyl$4} , {zyl.ind. ZW-Sp�tverstellung inkl. Dyn.vorhalt}
dwkrz_4 , {IgnitionRetardCyl$5} , {zyl.ind. ZW-Sp�tverstellung inkl. Dyn.vorhalt}
dwkrz_5 , {IgnitionRetardCyl$6} , {zyl.ind. ZW-Sp�tverstellung inkl. Dyn.vorhalt}
dwkrz_6 , {IgnitionRetardCyl$7} , {zyl.ind. ZW-Sp�tverstellung inkl. Dyn.vorhalt}
dwkrz_7 , {IgnitionRetardCyl$8} , {zyl.ind. ZW-Sp�tverstellung inkl. Dyn.vorhalt}
In any case, if, after pulling req AFR a bit, you see no dwkrz, you can always add timing and pull boost, which lowers EGT, provides a larger BTS and ATR safety margin, and may even add power since adding timing/pulling boost on small frame turbos can actually give you power. |

Just logged with CF/KR but now LDRXN is out of wack again. Also, how do I bring IDC down?

you'll have to log more of the PID parameters, in particular ldimxak_w , {ChargeLimitPID-I} , {Aktueller korrigierter Begrenzungswert I-Anteil LDR}
lditv_w , {BoostPID-I-Result} , {LDR, Tastverh<E4>ltnis vom I-Regler (word)}
unfortunately you have a good amount of KR, so you likely need to bring down boost everywhere. |

Now you're falling out of BTS so it is hard to tell whats going on with your IDC.... tapering to 7psi doesnt make much sense at all, though.
You'll have to be a bit more selective than just moving the whole curve up and down, and you need to decide on what fueling you want to be using, LAMFA or BTS.
I hope you are actually looking at these logs and not just waiting for me to tell you exactly what to do.

I am looking at the logs but I’m not sure what exactly I’m looking at like ignition retard or lambda control. Right now it’s bts.
