I did a log with what I thought would be my last revision for now, when I spotted this weird/funny looking actual boost pressure `pvdkds_w`. It keeps goin up and down with a difference of ~55mBar.
Does someone know how this can occure?

PID is hunting because your I is maxed out. Not good. You are nowhere NEAR your "last" revision with that persistent lde.
Log all of the PID variables. That log has none of them.

Because I have been on some forums a while ago and one moderator likes it all catagorized, and the other does not want any spam. I choose to make new ones because the subject might helpt the SEO in case other people are looking on google for the same problem. |

for the record, I'm ok with this here, or not, either way.
however, to get back on topic, i can't emphasize this enough: persistent lde is a very very very very bad thing.
If you do not know what lde is, definitely, for sure, your tune is nowhere near "done"

I tried to read about PID's, but I am a visual learner, and I find it realy hard to understand what they are and what to do when they are giving problems. I did a new run today with the PID's logged and I see allot of activity with them, I will attach it. Is there any way you can help me? |

Did another carefull read on the wiki, and saw that DIMX was too low. Changed 850 and 1000mBar from 2000 with 10%. Graph looks better but not perfect yet, might have to up it a bit more.

I tried to add those before, also mibas. But ME7 logger couldnt find those. I guess those addresses are different for each ECU or not? |

yes, of course. You dont' really need them atm, we can see pretty clearly what is going wrong - your i limit is far too low, or you can compensate in KFLDRL |

Okay, in that case I will read up on KFLDRL. Do you happen to have a log from a 1.8T where P I D are logged? Just as a example? I'd like to compare a good log with the results I am getting |

bottom line, your i max is way too low. |
