o2 sensers

[first timer 6.6]

can you shut off the 02's with efi live?

First I would like to know WHY you would not want to use o2 sensors, but a little more information like what engine/PCM are you using.

You can't actually turn the o2 sensor off from efilive, but you can disable codes from them being missing.

You can put the vehicle into open loop so as not to use the O2's.
