To everyone that has one does the right button acked like the left.My right button looks broken moves around and doesnt feel like i does anything is this normal.

 

The "MODE" button scrolls through the screens for the various sensors. The "RECALL" button recalls the lowest O2 reading and highest knock retard reading for your last WOT pass. If you hold the "RECALL" button down, displaying the minimum O2 and maximum retard, then also press the "MODE" button, the display will tell you the MPH that the min O2 and max retard occured. Does yours act that way?

Might want to read my online ScanMaster guide, its all covered in there:
