I will search and log those variables.
Can you tell me please what should I search for in FR to find info regarding pre-emptive retard?

Hi all
Just to bump this thread and maybe help someone facing similar problem.
I have fixed the issue now. Volvo S60R has two CVVT camshafts. There is allowed adaptation range for mechanical and installation tolerances. This adaptation was -6.xx degrees for exhaust and -9.xx degrees for intake. Both should be zero ideally, but impossible to achieve. ECU should trigger a fault if deviation is larger than +-8 degrees. IDK why it didn't.
Anyway, turned my cams a little and reset the timing. Both cams are -1.xx degrees and a positive side effect is that engine has a lot more torque and feel much more responsive. I always thought it was warm weather why it felt so slow this year. Actually it was wrong camshaft timing.
Thanks to all for thinking along!
