Why disable it? You can also use it to limit boost if LDRXN isn't what you want.
Also, why did you not post a log?
Finally, did you not notice you maxed your MAP sensor? Think that might be the cause of excessive knock?

More boost = more knock if ignition stays the same (im sure you leave last rl_w row 150% of stock axis data)
You should read the wiki and some basics before doin this creepy shit

Thanks guys.
I disabled it because i think my boost will follow ldrxn , but it not follow and i must increase very much IMX to make a little overboost.
My IMX was last row axis at 1100 and now it is 1350.
With other file (30.12.2018 - from attachements) 3 days ago at the same boost (but with KFLDHBN enabled) i received only few retards but with little WKRMA , only -0.75.
The log from yesterday with kfldhbn disabled is 02.01.2019-v56.
Thanks again for your advices

how looks ok from 2 logs? 02.01.2019-v56 log had retard -5 and wkrma -3.xx , i think too much
lambda 8.1 for protection , looks too much?
engine code AUM
injectors bosch 550cc
k04-023
kingawa actuator
sport air filter
downpipe 76mm
catalisator removed
evap, sai removed
i tried to control my boost ,load and torque but not enought
i don't understand why after 4700tpm my boost and load drop fast , i had imx set to 95% on last roq (1350 boost) , drl is set to 95% too
IOP is adjusted at 220 an MIRL to 98 at last row but my MAX load is 85%

this log is cutted and as you noticed and other users said its just too much boost for the ignition = knock if this is a 023 turbo then use a egt display and aim for 950degree celsius max! you are running too rich i think log your boost with fixed duty like it is described here: http://nefariousmotorsports.com/forum/index.php?topic=12352.0how much basepressure do you see with n75 disconnected? |

0.6-0.7 bar with n75 disconected
for linearization of duty i made invert like in your link i , linearisated the DRL and work with IMX , but i saw prj made linearization in IMX and work with drl
with or without kfldhbn disabled i have the same result , i disabled my kfldhbn because i wrote ecu must follow ldrxn , but not , the boost and load drop very much after 5000 rpm (and i modified IOP and MIRL too) but my MAX_load from log never exeed 85-87% and i don't know why too
kfldhbn stop the boost at 5500 at 2.1875 and i think it is disabled the boost follow ldrx who is 199 from 5000 to 6800 , but not
please need some advice
thanks again for your time

1) your boost req still makes zero sense
2) you still have too much IMX

NYET Please explain me more detailed this thing :"your boost req still makes zero sense".
I don't need so much overboost (1.5bar) or my ldrxn is to higher?
I understand next and please corect me if i wrong (maybe answers to this questions will be necessary to other people too):
1.the boost request is generated by ldrxn or hfldhbn
2.stock works with hfldhbn to limit ldrxn if is over chargeturboprotection
3.if i want to work only with ldrxn i must disabled kfldhbn and make it 3.xxx or higher?
4.imx and drl works the same in both case with or without kfldhbn?
5.if i disable kfldhbn the boost is independent of IAT and VVT?
6.is better with kfldhbn disabled ?
MANY THANKS in advance

NYET Please explain me more detailed this thing :"your boost req still makes zero sense".
Why do you have it rising to meet actual between 2700 and 4000? 1.the boost request is generated by ldrxn or hfldhbn
2.stock works with hfldhbn to limit ldrxn if is over chargeturboprotection
3.if i want to work only with ldrxn i must disabled kfldhbn and make it 3.xxx or higher?
4.imx and drl works the same in both case with or without kfldhbn?
5.if i disable kfldhbn the boost is independent of IAT and VVT?
6.is better with kfldhbn disabled ?
1+2) yes, the lower of the two 3) You can use either, one is a load based limit (dependent on IAT and VVT), the other straight pressure (conventional boost request) 4) yes 5) no, load based is dependent on IAT and VVT 6) depends on your goals http://nefariousmotorsports.com/forum/index.php?topic=14821.0title= |

Something like this.
Adjust purple until actual boost matches request.

Thanks a lot for your time and answers.
The KFDLHBN is dependent from IAT too, Correct?
If i make LDRXN higher than KFDLHBN i'll have a BOOST controled by HBN map?
Will try to reduce imx in that zone for purple line.
Please i saw you redefine the blue bold line for more request boost sooner. Correct? For this i must rise ldrxn.
Many thanks again.

when you hit full throttle at 2000 or lower you should see wastegate duty 95% for spoolup
