Turning off the right O2s

[fordfan1964]

I have a 2007 Mustang GT with airaid cold air, pypes offroad x pipe, borla axel back exhaust, and u7145 with airaid 91 octane tune.

I went into the OBDII system through the tuner to turn off the O2s and i notice there are three different choices to turn off. I want to make sure my car is gonna run its best.

What do the three different OBDII sectors mean and do? I forgot what they read because i am not in my car and do not have the tuner plugged in.

Which ones do i turn off?

If i turn them all off why do i turn all off and not only two or one bank?

Reason i ask is there is one o2 sensor pre cats on the driver side, one O2 in each of the cats and then one O2 post cat on the passenger side.

Please assist

The 3 settings under OBDII are:
Heater bank 1 downstream = Turn bank 1 rear oxygen sensor on/off
Heater bank 2 downstream = Turn bank 2 rear oxygen sensor on/off
Hego Config = Turn all 02’s off

You need to set these all to off in order for the sensors to be completely turned off.
