FAST Wideband??

I have everything setup correctly(I think). I got the max volts, the afr range, the histogram built, and the wires connected to the MPVI. When I scan the car and look at the histogram that was built, I only get a reading of 0.00. What could be my problem? Is it not seeing the wideband or just not getting a reading from it? I went by the sticky step by step. In the FAST box, you can select three different output values. The one I chose is called the Highres which outputs the range 0-4.096 which are the values I used in setting everything up. The other option multiplies the output by 10 which is used in alot of gauges I think..Anyway, anyone got any suggestions???

No one have any ideas?
