Hi,

today I got my injectors. It´s Bosch 0280158123 (630ccm).

I flashed an ori .bin-file and adjusted before:
KRKTE to 0.0576 --> calculated like S4 Wiki says.
TVUB to the values I got from this forum.
I left TEMIN alone.
FKKVS all values to 1

Started the car, waited some minutes in idle and drove some KMs. Feels good so far.

@prj
I´ve a question regarding your post before:
Where can you see that there is no boost control? Boost is following LDRXN/IMX like programmed. KFLDHBM was maxed out by the tuner.

Hmm okay, yes, it´s following IMX. But where can you see that it´s following IMX and not LDRXN? But this is normal condition under WOT or? See S4 Wiki excerpt below.

In my log rlmax is following rlmx, means boost is restricted by LDRXN?! --> as programmed

LDRL wasn´t changed by me or the tuner.
I only changed IMX in the areas where the log reported over/underboost.

I refer to this part of S4 Wiki/Did I understand wrong?:
"If your actual boost is not meeting requested boost, you may have to increase the PID I limit for 850 and 1000mBar. In general, you want KFLDIMX to follow what you expect your WGDC to be in the steady state, so after peak boost, you should set this to where you want the WGDC to settle. Note that PID trims (I-Regulation adaptation) may alter this limit. It should also roughly follow the profile of requested boost when it is tracking LDRXN. That is to say, if you have a flat max (WOT) boost request, you should have a flat KFLDIMX. The reason IMX is so important in ME7 is that in the steady state, P result is near zero and D is scheduled out with B_lddy. This means that I dominates.

On a WOT pull, I is maxed out due to integrator windup (accumulated error) so it is simply following IMX."

Hi again,

after I had adjusted KRKTE + KFZW + KFLBTS, the car feels better. I could improve the ign retardation.
Requested load peaks @ 220%/4000upm, falling to 170%/6800upm.

KFLBTS seems to be in line with my AFR gauge. Is it to rich?

The next step is to make an effort to check the boost control and understand the linked thread.

The car managed ~230g/s for the first time. The charge air temperature rose by approx. 10 degrees during a pull.
The duty cycle is 72% with the original K04-022 WG actuator.

Can I draw conclusions about the performance from the air mass? In some forums you can read for 1.8T with K03/K04 --> Airmass*1,3= ~PS.
How do I recognize the limit of the turbo?

Do I have to worry about the connecting rod? - I assume so?!?!

Edit: As prj already said.. There is no boost control. By changing LDRXN I only aligned the load curve to the actual boost. --> I should really put some effort in boost regulator

Quite not.
- Set entire KFLDHBN to 1.8594
KFLDHBN is max pressure to ambient ratio, so with this you're setting your boost limit to 0,85 bar in "normal" (1 + 0,85) circumstances. You can limit your boost with this map or with ldrxn.

For logging purposes, you need to set your boost request higher than your boost target in order to not get any interventions.

Make your kfldimx linear with maximum cell higher than boost target, then do cwmdapp = 8, and make runs with kfldrapp forcing wgdc from 10 to 95% or max  you can safely run. Then use ldrpidtool and just paste your kfldrl output, thats all

Just do not get any boost interventions during logging, this tool makes it pretty damn easy and accurate.
