hi all , after i disabled KFLDHBN ( i think like i found in this forum , made all values in the map 3.9844) i had retards mucj more like before and wkrma  at the same retard like before is higher
is it possible?

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

What engine and specs? which turbo?
why lambda 0,81?

rest is looking okay

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=12352.0

how 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

Why do you have it rising to meet actual between 2700 and 4000?


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.

yes

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

l

Thanks AEF but the imx and drl are 95 there., and i had overboost.
So i must increase ldrxn?
My ldr imx and drl

K04 wont work well with linear kfldrl
This boost levels usually ends up with bended rods

Thanks FUKENBROKEN for the advice about linear KFLDLR.
Do you sugest is better make linear IMX and works with flexible DRL?
Please wating your answer.
Many thanks in advance.

Pick a method (conventional vs precontrol) and stick with it.

Pre control requires quite a bit more up front work

BOTH will require fine tuning.

just copy it from TT225 file
or from stock k03 with fine tuning as nyet says

make ldrxn a little bit lower @170 is enough for safe run
then tune imx until actual pressure wont meet specified

do some iterations with lower specified load to made a smooth part-throttle
thats all

I began from a tt 225 file. the boost was incontrolable with imx and drl stock because i have an wastegate kinugawa with 1bar spring.
With 170 ldrxn car works like standard one but after adjusted it feel powerfull. First before i want to make myself tuning i bought a stage 1 for my AUM engine , and there was a 191 ldrx greatest value. I don't rise it very much.

as i wrote before read all of this thread and use the ldrpidtool

http://nefariousmotorsports.com/forum/index.php?topic=12352.0

this and the 5120hack will give you a great result

Thanks again to all.
After some modifications in my file ( reduce timing at maximum load where i had retards very much , reduce imx in overboost area to keep boost under 2550 mbar , and increase a little lamfa to 12.2 not 11.5 how it was) and I tried to keep overboost between 3000-4000 rpm at 1.5, today i made a new log and it is much better without retard (for the moment it is my scope) but something strange happen lie in logs before this.
At aproximatly 3950 rpm the rpm decreased instanly for a little period and there lose power like it see in the "CALC HP" function on ECUxploat.
What is saw in that area before this happend (rpm decreased) the timing advance is very strange and it is -9.
1 .Can be this first cause of decreased rpm?
or one of these:
2. my cluch is lost there but i don't feel it don't make its job
3.my wastegate can not suport that preassure (but if it can support much boost, but i think it can keep the boost higher before than , can ignore this option)
4.maybe my DV leak there

Waiting your advices please.
Many thanks again

There is zero reason to touch timing until you have boost exactly where you want it. Change timing back to 100% stock until you have boost exactly right.

Why did you ignore my advice about req boost?

If you still see timing intervention that isn't retard, you'll have to look at torque intervention (but you didn't log any torque intervention variables for some reason.)

You're also missing a few load variables, making diagnosis difficult.

Yes, your clutch might be slipping.

You might also have misfires.

I don't ingnore your boost advice, but i tried it to reduce and my car didn't work ok, works without power.
Tommorrow will reduce more imx and will see.
I reduce the timing at last row at maximum load and rpm area because there had retards.
Misfire not exists, they are logged.

i'll add mfa_w , rlmax_w , frxt and frxta_w in my log.
I don't find other variables in me7logger to add. If you can help me with other suggestions, please do it.

The strange thing is between 2 logs one one week ago with 386cc injectors (don't had this problem with rpm decreased and all values are the same with today) and one today with 550cc injectors( 2 problems , one is timing -9 at a moment , other is rpm decrease at some moment). Between these 2 files modifications are : injector calibration (tvub , krkte ,kvb , temin and teminva) and only iop and mirl at the last row.
Nyet , both logs and files versions have overboost in the same area and one of them not made problem.They had the same load and boost curve, and i think the same power.I don't forged my car so in some  100-150km the cluch i think can not be broken(it is made with kevlar - only 13000 km old ) , AND i think i'm wrong about cluch , because it is faild and it escape , the RPM must increase very fast not decrease
I attach both, and anybody have an ideea......to me i think something escape to me.
Only difference is a calculation of hp between them where 550cc is exagerated but not have any reason , because all hardware and setting are the same.

Yes, you did. Entirely.


That is ignoring my advice. Set up req to be where you want it, and set up IMX so actual matches req. There is NO reason to ignore this advice. None.

Your load will consistently go far over requested, and you may see torque intervention.

Also, that looks like your clutch slipping. The -9 timing might also be ARMD.

Thanks NYET!
"request to be where i want" = increase ldrxn?
Maybe i don't understood well.

And about cluch i understend from your graphic it fluctuate and don't make preassure all the time?

Hi again.
What can you tell me about this?
Power is lost at the same boost with actual following request
"-9" timing disapear but form other reason not from actual following request.
"-3" , "-5"retards with only wkrma "-0.75" appears sooner but i feel lost power when they exist
Decreased rpm not appear sooner but only after 5000 rpm but not so much

Boost looks MUCH better, good job.

the -9 was likely from ARMD (you still have slipping clutch, which might trigger ARMD) or torque intervention, since your requested torque was much lower than actual.

You might want to pull either boost (via LDRXN and IMX) or timing, possibly both.

Honestly, I'd probably stop driving it though, since your clutch is gonna let go at this rate - in that log it still seems to be slipping badly.

Or turn down boost significantly until you aren't slipping.

Unless you're losing traction... But i'm assuming you'd notice that.

Thanks again NYET
I'll try to increase the timing because today i made a test with a file with timing higher than mine with 5-8 degree and the retards and wkrma was the same.
Please tell me wkrma maximum accepted before detonation is ok -1.5 or -2.25 . Correct?
I'll se what can i do with my cluch but i'm very disappointed because it had 15.000KM and the disk was made with kevlar , the plate was stock new and the flywheel had 115.000km (was mine from new - i bought my car new).
I think my car with this version of software like looks in ECUxploat not have more than 220-230 hp and tq maximum 300ft-lb and decreased to 250 at the final.

I saw 2 cause of -9 timing :
1.cluch
2.actual boost over the map capacity

I attached a new log much better as form like previous, but one things not understood.
I increased IMX and all other maps remaining the same but the request is down and actual little up.

Looks like your clutch stopped slipping, but I am concerned that your timing is so bad.

What octane? You may have to reduce boost... or maybe even add fuel, maybe get AFR to 0.8 or so :/

-1 to -2.5 timing pull is fine.

But maybe pull boost and/or add fuel until you see 0 correction and see where you end up.

I drive with 100 octane fuel in Romania.
The cluch not slept but....the power is very bad , only 230 hp.....very bad with a k04 and 550cc injectors. What do you think?
My AFR is 0.82-0.84 , do you think i need less?
The timing is very low now i think , but i can not understood why i have retards.

With 100 octane fuel, definitely not.


Me neither, especially with those low intake temps. Maybe retorque your knock sensor?

Have you ever heard audible detonation?

I would really try to pull more boost and add timing back if possible. You may pick up some HP, believe it or not.

Yes , PETROM sell 99 and OMV 100 octane, maybe it doesn't have this octane , but i paid for it.
When you told "pull boost" , you want to tell decrease boost?
I'll add timing for the file for tommorow.
Do you tell me to increase request boost and actual boost too? I think if i'm over 1.543 (limit of MAP sensor) my boost will make again more problems! Corect?
I don't heared any detonation ever!

Hi again.
Today i can not made a log because here snowing.
Maybe next week i'll remove the knock sensors and clear them, but i must have a good dinamometric key.
Nyet do tell me if i understood well , my timing is low, correct and with 100 octane and lamfa and low intake air temp , i must not have retards ?
1.Can de false retards from my downpipe or exhaust?
2.Can be bad calibration of injectors, because i have them from 2 weeks but i have partial adaption between "0" and  "-3.2" and idle adaption "-4". appropos idle adaption if my partial adaption is ok can i calibrate from FKKVS or from TVUB , because i don't want to change the krkte.
3.Can be a bad injectors or fuel pump, but i think if one of them is the problem for retards , i must have misfire in logs?

yes

Thanks.
I wrote again in reply #34 with other things and if youc an fgive me your advice too i'll be glad
And i want to add point/question 4.i have a AUM engine 1.8t with vvt but i begining my tuning from a BAM file and the vvt kfnwse is different from my original 150hp. It had enabled vvd (-4 degree between 2500 and 4500 rpm).Can be this another problem with my timing , i saw in my log my intake cam arrived to 24 degree not 22 who is maximum to change. in this area of rpm when the cam is to 22 degree the kfzw2 is activated , corect?

Would suggest to have kfzw and kfzw2 the same.
Use the vvt switching like it is in a k04 engine. just copy this from a bam or amk file.

Hi AEF and Thanks
Before today my file was a BAM file , without modified VVT , only kfzw and kfzw2 i made the same values , but today i made like original file , with kfzw2 little higher values like kfzw and it work much better.
I saw the kfzw2 is active netween 2520 and 4500 rpm like kfzwse told to the ecu. It is something strange here because in kfzwse activation is only before 4000rom but my kfzw2 works after 4500.
