Here is log from dynopull, from 2500 to 3000prm ecu limits boost/load request, no matter i increase LDRXN or adjust VE maps. Similar situation is on accelereation thourght gears, the boost/load target climb to full(from ldrxn) just before peak boost, no matter on on rpm. Its on mafless hacked 180hp wideband software. Is it MDFAW load shock damping?  |

Why are you pointing at plsol and not rlsol  |

Its not HBN, i set i afterwards to limit my max boost at untested hot weather(its flatlined throught revs). With higher, its makes still the same. I just used to look at plsol first, as its at the end of chain:) Here rlsol doing same weird think, obviosly. This is log going throught the gears. See rise target from 1.2bar to 1.4bar just at peak boost , why it is not 1.4 all the time?  |

A single WOT pull in a single gear with the ecuxplot filter turned on, and RPM as x axis (not sample) will show this. Unfortunately, you didn't actually post a log. rlmx and rlmax might be informative. |

LSD is ignition intervention, stop throwing fancy terms around and l2tune.
And post logs.

Log mifa, misol, and misopl1, also I need your IRL and IOP tables.
And why do you need more requs boost when your turbo can't give so much boost at that RPM?
What turbo are use using?

Ok,but it will take some time, car is now undergoing mechanical changes.
My experience is to have a stable boost request before are of boost meeting the target , to easier PID control to catch the target. As you can see, this is not exactly rpm related. Sometimes target is still moving just inside peak boost, so sometimes PID can have problems. Its not that major here, just im curious what it is, as im not capable to solve it with my actual knowledge, and dont want trying wild blind changes of for me unkown maps.

Yust post here IOP and IRL screenshoot, I will see can I read somethnig from it
Your turbocharger is secret or?

Oh you mean during spool... You say you've moved LDRXN up in this range and HBN isn't limiting until boost meets request.. are you requesting enough in IRL for this range?
To be honest, I don't understand why you're so concerned, PID looks to react fine.. spool is slow but that's not due to load request

Here it is, but i think its not an issue, if you look at charge and turbo limit protection on log pictures:  One thing i forgot to mention, engine is 2.0ltr stroker, so i blindly set recommended 2ltr values of KISRM and KUMSRL, found on this forum. Turbo is G25-550 .49 |

Your rl_w at 2750 is about 112%
That to IOP you get about 60, and than to bla bla.... to misopl1, then again to IRL, your req load is 180%. So everthing works normal
If your rl_w incrase(when turbo start to spool) your rlsol will incrase.
you can add more IRL at that area, but i would defintly not suggest you to do that, there is no need to do that,and part throttle can become shit to drive and get into torque intervention.

Your IOP maxes out at 82%... that correlates to around 190% load, you need more IOP to reach higher levels in IRL

BlackT: make sense, i just extrapolated last two rows i think from 180file, so its limited in these areas. Thank you.
