Well it should be updated if you just bought this...unless it was used. Because I am pretty sure they said they update them with the latest firmware before shipping out.
Now to the part in bold....did you make sure to turn your key to the on position(without truck running) before you plugged the gryphon up to the cable?...And I found that the check gauges happens everytime I go to program my truck especially if it has done been cranked...something about the programming overiding the sensors at the time?? I think that was the explanation.
