my o2 cc count is not moving and i may be wrong but didn’t the convert used to show unlocked. It only shows locked now and blank when it’s not.
If you are using a Velosyty chip, "CC" is is closed loop wide correction, not O2 counts. So it should be at 128 most of the time. It will go up or down at WOT, if using wideband correction. The converter lockup readout is correct, blank when unlocked.
