Just had a glance at your logs.
You're massively overboosting @ 3000rpm.
So much so you're actually beyond the MAP limits,
who knows what boost peaks at.
And funny enough, your 6° timing pull starts at around there.
Get boost sorted first, then worry about knock limitations.
It's my own fault. Should have looked at logs first,
but not optimal on my phone with only Google sheets.

Yes and thanks for this reaseon i asked about my overboost because there is the problem. I tried to reduce duty cycle at the last line between 2000 and 3500 rpm but the overboost it the same. Any ideea if you look at my printscreen maps where is the problem and why it make oveeboost (this is clear produce knock/retard). Thanks again for yours advices

I tried to reduce duty cycle
In IMX? how did you determine what to do if you didn't even log the PID variables? |

Thanks nyet but there i modified few days ago but without result.
My overboost exist and are the same 1.5 bar.
Please see modifications in attached picture for n75
Today with bkr7e sparks and 99 ron fuel (retard is -6) the result is worst than pfr6k sparks and 95 ron fuel ( retard maximum -3)

I think this is not about sparks / coils...
I have similar problem on AGU me 3.8. Timing retardation after 4700rpm. I´ve replaced coils (R8 red) and sparks and no change... Replaced knock sensor not helped too.
so ...

Log the PID variables. Pull more IMX.

New kfldimx adjustment on last line like in attached picture and see the logg attachement too
Overboost are the same 1.55 bar but no retard
Do you think make some changes in KFLDRL for escape the big overboost because in IMX i am to the limit
I'll make a new log tommorow with the same setup and will see if NO retard will keeping or was a coincidence.
Many thanks again to all.

Please make some logs of boost PID, it'll make everything less painful.
But try and adding a little D.

Your IMX looks like crap. You have a gigantic hump in it.
Your columns should all be monotonically increasing.
Also, why are you not logging I and i max

Your i limit should be around 60ish (post DRL, you may have to back calculate).
Also MAKE YOUR DAMN COLUMNS MONOTONICALLY INCREASING

What do you think?
