First off, I am a member of Chuck's group, but I figured I would post this here for future reference.
In the PFC commander screen, after increasing the richness for colder intake temps (we're starting to hit low 50s F at night here) I no longer see max knock for the night, how do I get this to turn back on. I still have the little sliding bar, it just won't show the max in number form. I monitor: boost, knock, IAT, Water Temp. I was using the datalogit to tune also.

 

Push the up arrow from the monitor screen.
