Default O2 Readings on EFI Live Problems

I just got my new autotap hardware and EFi Live. Everything is running great with these items except for the fact that the AFR gauge does not move!! Here is my current exhaust mods:
2002 Z28
Hooker Headers, Mufflex Y-pipe, o2 simms in the back and of course my o2's are plugged in in the front.
My problem is i want to tune my car with my maft but i cannot even make it give me my afr. Can anyone offer some advice. In the past before i had o2 simms i was getting a code for oxegen sensor hearter. What is that?

ps: I have dynoed at 335hp with a 11.9 afr so i need to fix this prob asap!!

Send me a log file taken when the AFR was not "moving" to efilive@blacky.co.nz

I guess you're aware that the AFR does not "move" much at all because it is a commanded AFR not actual AFR. Generally, the commanded AFR will only move in response to large throttle movements.
