Default Got the Knocks

Did my first real run with Datamaster hooked up to the car and I looked at the knock count when I was done and it was over 11,000!!! Can this be right?? I haven't done any tuning to the car....yet. Yet the fuel map graph was showing a pretty much rich across the board reading. Stock exhaust with no leaks that I can hear. Slightly noisy stock injectors.....Any other ideas?

11,000 is way to high. As far as what's causing it I'm not sure.
Have you installed roller rockers? Or anything else that can be causing false readings? Have you checked your timing?

No roller rockers as of yet. No headers, stock exhaust all the way out. The timing on the datamaster readout read from 15* to 40* timing advance.
