Can someone tell me what is going on with my civic ? On regular gas (E27 here) of any gas station, I always get very high K. Counts and K. Control during long trips. I thought this was because of the +3 calibration but I tried it with factory settings and same results, so I am starting to get worried after I read somewhere that K. Control over 90% might be trouble...

My car has less than 10k miles on it and has no modifications.
On a trip with stock reflash I get almost the same behaviour on K. Control, but a little lower peaks (like 90% instead of 104%). I also get lesse mileage but I guess this is because stock AFM calibration is 10% richer on the low portion, where my custom AFM calibration is close to stoichiometric.

Info:
AFM calibration in progress.
Fuel: E27 regular gas (92 RON / 88 AKI nominal but quality control here is poor)
Ambient temperature during datalog: 25°C (77F), dry sunny day.
Trip was mostly level and uphil terrains, driving was granny style with soft foot.

Car is a 2019 Civic Touring 1.5T CVT with 37820-5AA-M61 ECU.

It looks normal for a lower octane fuel.

So it is normal for K.Control to go as high as 100% and over ? Wont this damage my engine in long term? I read somewhere in one of your replies that this should get me worried.

In my everyday commute it usually stays below 80%, but I travel a lot and then on the highway I get these crazy high K.Control.

K.Control can go to 140% I believe. The ECU is doing it's job altering the ignition for the fuel.
