You solve 1 specific problem (@wot on a third gear in mid range rpm) by the hard limiting of kfldrl
Thus works only with these conditions
And linear drl goes pretty well on a big turbos with ext wg but not in this case

Not true, it work realy well so far. No mather what gear, what RPM and how much throotle.  Real real smooth and responsive boost in every area

You might as well run it off of LDRAPP.
It's pretty much open loop at this point.

I want to do it right way. No cheat, even if it is working right. I will do some more research about ME7 PID. Then try to tune it again

Imx and ldr maps looks strange... You want 95 dc n75 everytime at spool... Also maps should be somehow smooth and linear... You are setting 95dc at spool for 1000mbar and 80dc at 1300... Ldr map Also is not linear... Bad idea

I didn't bordet with that region beacuse in low RPM turbo can't open WG, so i the same what DC is it

Yes, but with this seting on actuator i have huge spike on 95% DC . It must be limited whey before the turbo get close to desired boost.  80% or 95% when this little turbo spool up, the diffrence in spool speed is insignificant. And I like more this linear spool at little lower DC, the car is nicer to drive

But I will try with RS4 values for IMX and LDR to see what will hapen
