Just got an LS1M and have been playing around with it. My car is all stock. I noticed something that I think might be weird but I'm not sure. http://scandepot.net/viewscan.php?pk=5752 is one of my scans. The O2s are around 800-900 most of the time, but then it drops down to below 100. Is that normal? Or is there something wrong with my O2 sensor?

Also, are there any good posts anywhere on understanding all the parts of a scan? I've heard of most of the terms, but never really known what they meant, like Injector Pulse Width, Long and Short-term Fuel Trims, Fuel trim Cell Number, Injector Duty Cycle, etc etc.

Thanks

At idle (when your off the gas) your O2s will jump all over the place. Sort of like the A/F gauge does, here a link to my scans, this is from a stock 97 GTP.

There's a post somewhere that explains it all, I'll try to find it....
