Sorry but I don't undestand why. I read all of the 18 pages from that topic and did everything based on that. What I didn't do is switch off LDDIMXN.
My KFLDIMX is linear, I've choosed the axis values from the logs what I did.

What I would like to try is change that KFLDIMX map values that at 1450 will be 80 and make the linearization. Change the D parameter too to prevent big overshoots.

Whatever you did, the result of IMX+DRL is too high. Keep IMX linear, but something is amiss with DRL in that region

What should I do? Yesterday I calculated with lower values in KFLDIMX and hopefully I will help to open wg before reach the limit.

I've just set the kfldimx output from 90% to 80% at 1450mbar. Is this also good?

I've modified the kfldimx regenerate the kfldrl add some to q2 and switch off LDDIMXN. The result is not much better.
What I'm thinking currently is modify kfldrl below 3000 rpm to open the WG a little. 2750 rpm with 70-80% lower the 95% requests.

No, increase your request so P provides enough wg during spool.

What is the problem with my boost request now? It is flat and 1,35bar is enough for my config. I cannot set the pid to handle the current request?

request more during spool so the P part is large enough to generate 95 dc

?? Does it solve my overboost problem? I'm running 95dc before I reach the target. Can you explain a little bit how does it solve the overboost?

Thanks for the help and sorry if I ask stupid questions.
