Done a log in 3rd gear, only got obdeleven to work….

Well „some“ ignition retard, which is, in my opinion too much. maximum 2.5 degree would be acceptebal, or I am wrong?

So…. What to do? Believe thoose KFZW and KFZW2 maps on highest load that they are okay and something on my engine (no fault codes) is not okay OR retard all (?) the maps with 2 degree?

Ignition is a „hot“ topic, one can easily destroy stuff, so what I want to be sure everything is okay.

By the way, car is a mk5 Golf GTI Edition 30, bigger do88 intercooler, HPFP and pre-cat is removed.

Yes you have too much knock.
Timing seems fairly low, are you running 98 RON at least?

For logs that are actually useful for tuning check link in my signature.

Yes, 98 RON of course.

Sorry, I couldnt add more labels with obdeleven.
So how should move on? any ideas?

worth to mention, plugs and coils where replace 10.000 km ago.

Not even labels, your logging speed is like 0.8hz.
And you did a very long pull.

Reduce timing, reduce boost, make it leaner up top, don't run 0.9 at peak tq, it's not a NA engine.

yeah, obdeleven is bad…

of course those lamda numbers are too rich, but thats because the ecu goes richer due to the ignition retard ( that curve multiplied by that factor map multiplied by the lambda component protection).
