You always have a choice of what to make the logs show you.
What exactly are you wanting to see? You have to decide what you want to see first. I like to keep an eye on about 25 things when I log, but everyone is different.
EFI user here, so my logs wouldn't help you.

this was a drive from home into the city...
I filled a lot of data cells..
had my wideband in passenger side o2 bung so you'll see o2 MV on that side stuck at 450...
2000SS
in SD..no MAF at all
custom intake
jet hot longtubes and dual exhaust with dynomax bullets

Mine does the same thing. I tried changing the reported rate to 1/6 with the LC1 programmer, but no luck. It has to be a wiring issue. Wonder if the 4th pin on the NBO2 connector needs to be grounded to the exhaust? I know which ones are the signal, heater power and heater ground from a '99 C5 shop manual diagram. But, I get the feeling that last one isn't supposed to be connected to the EFI Live interface.

you gotta run a seperate ground to it if you want to use it as narrowband...
I have a wrietup with diagram in the stickies..

I just wasnt using my wideband as a narrowband in that example.and teh pcm reports 450 when its not connected

I used a stock O2 connector...Pins C & D for my heater ground & switched 12v source, Pin B for the NB sim (analog A), and Pin A for the ground to the data logger. The calibration/led/push-button, system, and analog grounds are also connected to the data logger's ground. I get good readings for the WB (analog B) with a very minimal difference in commanded vs. recorded voltage. Just can't seem to get the NB sim to work. I need to rent a gun and buy a bullet I guess.

might look at the connector really close...maybe you just got them backwards somhow on pin a/b..in which case your wieband noarrow output would be fried..also check to see if you have any voltage period on the narrowband output..check with a volt meter....
I also set the warm up voltage to 450mv as well...just so I have it that way instead of high impedance
