Maybe he didn't make 1,2bar at 2250 rpm but on 3000 he should make it.

Yes I read that and I know that there are many factors e.g. the alignment of the stars and the moon

I have orientated me on the community project and there, the settings are similar.

On Page 36 FlyboyS4 posted a log from his boost and you can see it runs up to 18 Psi and


The thing is, I want to tune my ignition for optimal use with Super98, but before that, the boost should run as desired.

Logs are in the attachments.

Got some wired effects, if I am in 3th gear and go full throttel from under 1500rpm, the boost rises at ~3000rpm a short time to high and goes then instantly to much down until it picks up cuorage again.
You can see it in the log "3th gear full"

Is it maybe, because the Wastegates are completely open because he couldn't generate the desired boost, but then he become enought rpm for this pressure and the Wastegates didn't shut fast enought ?




Half 3th gear from over 1500rpm

S4 wiki says to change Q2 only as last resort, I first try to decrease KFLDIMX by -5 on 3000 - 3500 rpm.
Hope thats not to much, but I will see.

So I am really at the End with my knowledge, I don't know what to do anymore, I hope, someone could help me.
First, I got no Overshot Problem anymore.

My Problem is, the Boost will not follow LDRXN, and the weird thing is, the DesiredBoost dosn't follow LDRXN, too as you can see in the new Log (And yes I know, that I have to lower Ignition a bit at higher RPM).

The funny thing is, in higher gears (5 & 6) I came to ~ 1.3 Bar boost.
In the lower ones maximum ~1,1 sometimes a bit less.

I Am not sure if it is a Software or a Hardware Problem.
So because of that, I did a lot of Troubleshooting:
- I checked the Boost System for leaks, but it is in good conditions, no leaks.
- I replaced the N75 with a brand new one.
- I tried it with putting off the connector to the air mass flowmeter.
- I looked if VCDS Boost Value is the same like my Boost gauge and it is.
- I put off the hose from N75 to the Wastegates and I easily became 1,5 bar boost (there could be much more, but I think the Turbos didn't like it).
- I have changed KFMIRL a lot of times with different Values
- I have changed KFMIOP with different Values

Maybe someone can look at my File in the Attachments
I don't know why, but I can't upload it here as Attachment, so here is a Onedrive link with the files:

There is one csv File in there.  


If you see the log, you see what I mean.


Edit:


I am also not shure, how the Wastegate Duty Cycle should look like.

rlsol is following rlmax perfectly.

rlmx however is much higher than rlmax.

Assuming ldrlts isn't interfering (KFLDHBN), the other possible interventions between rlmx and rlmax are frxta (IAT), frxt (tmot), fldrrx_w (KR), ldrlms (LDPBN, but only if B_brlmx is set), and LDORXN (but only on E_ldo).

Hi Nyet,

thanks for your explanation!

Okay, I will try to increase KFLDHBN and try it again.

How could you show the Parameters like ldrlts_w in the ECUxPlot ?
I can't find them

Got it, thanks !

So increased KFLDHBN to FF but no changes.
I forgot on the ride my notebook for taking logs, so I will do this tomorrow.
I will also check my N75 again.
