I've tried to connect before starting, but after starting the engine it throws me error os_sendbuf(len=3, data= 01 B7 B8)
And TCU goes in limp mode.
Will try pulling dash fuse. Thanks!

I finally connected the logger.
First I connected Nefmoto flasher. It opened 0x01, then 0x11 session. I closed nefmoto (it was still connected) and connected the logger at the same baudrate as nefmoto (125000, 0x11).
I think ME7Logger does not open one more session or something like that. Nefmoto does.

No, while ignition was turned on, then logger, then I started the engine.

I have that problem on friends TT 512 kb ECU. While ignition on i can conncet. When engine is runming I can't connect. Vcds lite, nefmoto, me7loger no one of this won't connect while engine is running. (Vcds 11 can connect)

Run direct K-line from OBD - Ecu.
It will always connect.

Try another baud rate. For example 9600 nefmoto, then 10400 ME7Logger. |

Here is my log. Now I know that P-component is pretty weird... at least for me.
P-Anteil: ( LDRQ0DY ( bzw. LDRQ0S ) - KFLDRQ2 ( bzw. 0 ) ) * lde = ldptv
What did I miss? Please give me a hint.

That isn't a log, thats an utterly useless screen shot.

The question is not about the log, but about P-component.
Anyway here is another problem with the hardware (underboost), so first I have to fix it.

We can't use that log to find problem, put CSV file so the users can view it with ECUxplot

Thank you all for the help, but N75 was dead, so the log is corrupted. I'm gonna log it one more time tomorrow.

Here is the log. Please take a look.
Maybe I'm wrong but the problem starts between 2800 - 3100RPM. The boost goes up from 2000mb to 2400mbar and it takes only 0.3sec
Strange turbos... 0.3 bar at 2000RPM... So first I would like to set LDRXN according to this. In that case lde will be closer to 0.
And also I'm going to set DC less started from 2000RPM, so it has more time to reduce boost.

i see 2 probs here:
1 boost cannot be controlled after 6k
2 pid
get a pressure test wg lines. check for leaks, actuator rod moving etc. probably one of them faulty
check n75 in another car
log it with TVLDMX = 0 and ldrxn ~180
if you see boost goes high after 6k with then probably wg hole should be ported
as second
did you flat KFLDRL? k03 wont work good with that
is it stock springs in actuators used?
cap DIMX @3k ~~~40%
raise Q2
play with Q1ST

Your IMX is a mess during spool. Bring it down significantly. It should be flat until you reach desired boost
