My QC has only been in my 05, 3500, 5.9 Cummins for a couple of weeks and today everything is locked up. That is, weird numbers in each pane that stay constant. Is there something I might have done wrong? Worked great for two weeks. Any ideas.

I cant find a phone number for support.

 

im sure someone will post the number soon. qzilla is a regular on these forums and offers some great customer support!

817-306-3879 is the number on their website under "support"

I didn't see an 800 # anywhere...

Check your ground. If it is not grounded properly it will display min or max value for all gauges.

 

Does it change at all when you turn the truck on and off?

 

Thanks everyone for the help. I contacted Quadzilla and they had me send the Commander in. They will repair or give me another. So far seems to be great service from those folks. How refreshing.
