Hi,
Does someone knows which function in FR is responsible for overboost throttle cut? Page, name or anything. Thanks!

There is no throttle reaction to overboost though. Only if load is higher than spec.

Are you sure? I thought the same, but even with rescaled load on WOT (so it will never exceed specified) there is a throttle cut. |

you are forcing to do your throttle to do what your PID should be doing.
Fix your PID, end of story.

With all due respect, but I didn't ask for solution. I wanted to know where the cut is coming from (function, not the reason) |

I wouldn't say it does nothing. The air mass dropped about ~30g |

Then on top of everything else wrong in your tune, the throttle and tq isn't calibrated properly either lol. |

It may be true, anyway, it doesnt matter now. I want to know where is comes from as a fuc tion, not as a reason. I know that recalibrating PID will solve the problem. The purpose of the topic is not to solve the problem. It’s about gaining knowledge about me7. I always thought that throttle cut is related with TM interventions (load req>actual). But the log shows that its overboost related too. But i cant find the function where. |

Fix your overboost.
Also that boost request for that load is very very low, did you touch KFURL or something?
