The cursor is set to the point where lde is lower 100 and d part is 9. You can see the data at the left side. |

lde has to drop below 10 or above 100 to trigger lddy off/on. See also hysteresis. i don't see what is actually going on with lde so i can't tell. Either way, D has to overwhelm P and I such that you see a drop in dc well below the I limit and also *well before* lde hits 0. |

Orange circle... why is your imax jumping here?
Added yellow line should be your dc.
it should come down well before lde=0 and should settle on imx soon after lde=0

It's jumping because my boost request was not stable. It changed from 2350mbar to 2330mbar. Yes I would like to see that curve on dc. |

Really thanks for the patience and for the help. I've learnt a lot about how does the boost pid work. At higher rpm's it has a little overboost but I think it is in the acceptable range. |

They're not directly related and they're never really cross checked.
