 ### Breaking Changes
  - Closed loop idle timing behavior changed to no longer fall off control as entering/leaving the idle region. It now sharply engages/disengages upon entering/leaving the idle area.
  - Idle phase logic uses the same idle detection thresholds as the main idle controller instead of its own thresholds.
