log and see whats your knock sum doing and actual timing advance
Here's a log file that i did before, Green cells are exactly when the car is bogging. A typical scenario, Highway driving doing about 50 mph and give it some gas and the car will literally fall on its face.
In case you check the logs, Do you think the RPM vs ignition timing is normal (green cells) ?
You attached a CSV file which only contains the raw data - only the *.xlsx file format contains the formatting
You failed to log the knock sensor which is not very helpful when you are concerned about detonation
Looking at the data I would say you've got numerous problems and should see a tuner
The AFR is constantly in the 14.x range which is not right - it should go rich under acceleration to at least 13
It did go VERY lean (19:1) around 3,300~3,400 with no throttle - you need that fixed ASAP!!! (may not be the base map - could be no decel enrichment)
The ignition advance is a total and utter mess but there is not enough data to know if it's the base map or other factors

I have always thought that knock strenth in cipher is useless !

The logging was done with partial throttle only, Nowhere near WOT, So there is no way that the AFR targets are in the 13s while you are cruising at 2000 : 3000 RPM !

I have always believed that going lean on deceleration is normal since there is a fuel cut !

That is why i wanted to try to use the main map as a high detonation map, But still i didn't get a clear answer if it's possible or no!
etunes are always locked, if you want to tune it yourself you will need to download the master rom for your ECU (you can do this through the rom editor) and start with that. You do not need to dump the ECU.
My High Det map is like minus 8 degrees timing everywhere, so if I do knock severely under WOT I will definitely feel the power loss, let off an know something is wrong.
