The logic behind getting into rough correction mode is quite convoluted - not just Rough_Correction_Minimum_KC_Advance_Map_Value involved. This is a good reference - http://www.romraider.com/forum/topic1840.html |

To exit from fine correction mode to rough correction mode, ALL of the following requirements must be met:
Of course this all applies to a car that isn't ours... it could totally be wrong. I have found through experimentation that using less than 3.9 in the advance table keeps it from dropping, that's all i know for sure. then again, i often set it to zero in those areas just coincidentally, so maybe that's why it doesn't seem as though the table matters. i could swear i remember running 0<value<3.9 in the advance and not seeing it drop, though i cant be sure about that without correlating old roms to logs or testing it again. |

Yeah, it is odd that that's the case. Maybe setting that value to 0 changes the way the logic handles the advance tables - I've never really looked at it closely. The logic is pretty much the same as other Subarus, incidentally.

Code:
If (in fine correction) { If (pulled more than 4 degrees or the ECU is unhappy) { Goto (IAM correction) } If (Large/rapid change in engine load) { Goto (FBKC) } } else { Check to see if any adjustments need to be made Stay in FLKC correction mode } If (in FBKC mode) { While (engine load is rapidly changing) { Check for knock and pull timing if needed When (Done) { Go back to previous mode } } } Looks like I'll need access to flkc @shiv@vishnu to confirm for myself or @Td-d /anyone with previous subaru platforms to clarify if the number in the map that dictates where coarse correction starts is at 4, and since ours is set at 0 so behaves differently. |

Most of the tip in knock I see shows up in fbkc. It'll write into fine learning sometimes though, particularly when tipping in to a long pull.
