Yep prj, you were right2 main variables are the output from MDBGRFZG:
mibgrfzl_w (slow path), It goes towards KFMIRL
mibgrfz_w (fast path), It does go towards ZW
Funny thing is bit 1 from CWMDBGFZ is from factory 0 (00001000) at least in a fully defined gti mkV I have and matches my cupra if Golf's kp is well defined. Which makes mibgrfz_w (fast path) always 100%... Thus, people shouldn't be experiencing timing intervention at all. At least for nonAWD vehicles, cause miallbgr_w is ignored.
