I don't think it matters.
Ugh its so hard to figure out whats happening… The boost gauge is also fluctuating I close to the point to just stop driving the car and sell it… |

According to your logs you did everything right. Duty cycle is around 0% but the boost is increasing while the throttle is closing.
Disagree. I don't see this at all in this part of the log. Where are you seeing that? Log PID vars. |

Sorry, misread this as there are two independent problems. The main proximate issue (imo) is crazy overboost at peak boost, which is bad PID tuning.
I'd start by getting that under control.
Not sure what is going on with the diverter valves; that is a separate hardware issue that won't be solved in software.
anyway, this right here is a good reason to never do an n249 delete.
He says it goes limp, but never posted if he is seeing codes. I am not so sure the offthrottle spike is causing the limp.

Dear Nyet, i never get any codes. it just goes in limp every time i let lose gas pedal at high rpm WOT. and yes i indeed did n249 delete |

Nyet,
I have to do ignition on and off to get out of the limp.
after ignition is on the boost is back

Start with the proximate cause; your PID tuning needs a lot of work.
if you still get limp mode after you fix your PID, reconsider the reasons you deleted the n249. Do you have good ones?

I made some changes by analyzing your bin and log.
Reactivated some closed saftey features, tweaked boost pre control/adaption, ignition timing and lambda/fueling.
Knocking is quite apparent, are you running original compression ratio?
If so, I would recommend NGK BKR8EIX.
Try to figure out what I did and if you test it, always be careful, it's at your own risk.
I'm sure there is some more work left to do...
Hello Leonhard see file attached log with your file regards...... |

still missing PID vars, but that overboost looks almost under control. IMO IMX is still way too high.
You may eventually be forced to put your n249 back.
did you rethink your reasoning for removing it yet?
BTW this forum is DIY, others should not be modifying your bin for you.

I removed the N249 + N112 + SAI Because the SAI is broken.
so i thought just to remove it all
i can install all back into the engine but i need a new SAI.

Also i am trying myself since June without any good results im just to stupid to make a good tune myself.i dont understand what u mean with "PID Vars" i dont have any clue of how maps really work in ME7.5 im trying to learn here from my mistakes. |

SAI is fine to remove. You may just want the n249 back. |

Thank you, i will log these also can i also just put back my combivalve and n249 do i have to put my emission stuff and N112 back into position or can i just block off these ports? regards. |
