Desired load is used for the filling adjuster (FUEDK).

Thanks, now I see... Btw PID is completely stock as is turbo (K03). Yet I can't understant why wastegate DC isn't at 95 whenever I press gas pedal 100% and load haven't reached the target?

the PID driven by lde (ld error) not load deviation. Please review the FR :/

"ld" is NOT load....

I can never tell whether your disagreeing or not, but exactly.

Charge control or filling adjuster (FUEDK) as part of load realization (FE).

but actual/desired load deviation does not drive LDRPID :/

I should correct my previous statement.

rlsol is evaluated against rl, but only for calculating throttle angle.

Um, guys, so KFLDRL is there to configure how much wgdc ecu can use on each pid correction? Ie: If duty cycle from PID returns as 10% KDLDRL maps it to whatever RPM/10% cell is? In my case it would be  38% @ 4000 RPM? Right? So basically this maps allows us to configure how fast PID will get to the target pressure? As in step size of corrections?

If we set this whole map to 95% then even smallest wgdc requested from pid will result in 95% and thus fastest achievement of target charge but also sinusoidal PID? Or am I completely wrong on this?

If you aren't already at 95% during spool *even with a stock KFLDRL* you are doing it wrong.

That is basically why I said what I said Smiley
Specifically because desired/actual does exist, since it subtracts rl from rlsol and that goes into throttle angle set point.

Hi all,
i know this is old topic but i didn't want open a new topic.
My issue,rlsow_w not ever following to rlmax_w and rlmx_w
rlmx_w seems 254 but  rlsol_w seems max ~220 in my logs.
is this a torque intervention? or something else ?
maybe my kp axis wrong (KFMIOP) , i don't know..
KFMIOP
@166DE x-axis@13074 and y-axis@16840 in my .kp

Log and ori attached
thanks in advance

Are you sure that your turbo can make more power? Where is WGDC?
Look at you KFMIRL values, they have smaler value than a LDRXN.
I must go, but tomorow i will explain better

Turbo is a gt28 with external wg.
checked repeatedly, KFMIRL values  they haven't smaler value than a LDRXN

LDRXN go to KFMIOP,  you get "misol"... "misol" go to KFMIRL and values you get after conversion are lover than a LDRXN values
So raise KFMIOP or KFMIRL values at "misol" you get from log

What about your KFLDHBN? Can you log it?
