Pinging!!!
I'm wondering if my digital knock sensor is working. My 2k 5spd pings on anything but Premium. Shouldn't the knock sensor kick right in and retard the timing. The dealer said if anything was wrong the dumby light would come on...any thoughts besides always using premium, I want to make sure it does work properly.

I think SprintMax is right 
The VQ30DE runs a relatively higher compression ratio that requires 91 pump octane fuel or higher.
Putting less than that in your Max would cause pinging, but you're right, the knock sensor should be picking that up and retarding the timing (with the side effect of dropping your performance and mileage) so that the pinging doesn't occur.
You might want to have Nissan take a look at that, but you shouldn't be running anything less than 91 octane in your Max in the first place anyways, so it's sorta besides the point, but not really
