First restore all fault classes in your ECU. You most likely did not do code outs correctly.
CWKONABG is not responsible for working or non-working lambda correction. You are responsible by "coding out" things wrong, or you most likely changed something wrong.

As far as I remember, on 8E0909* there was no issue with it.

That said, there is no need to change CWKONABG to zero. If you want to disable SAI and cat heating just set FHOKH to a very high value.

I am trying to figure out what turns off short fuel trims.
My focus is main on scenario where short fuel trims are higer over 15% than after some time ECU shut them off without DTC, after cycle ignition they are ON
Sometimes during tuning trims on LPG that annoying me, if it possible I want to turn it off or at least extend that time
