my bad.

Tons of people run widebands 100% of the time. It's a good way to keep an eye on things.
I recieved my reply from innovative and dynotune. Dynotune said it was designed to be run everytime the car is on and it may actually cause problem to have the car running and the sensor not be on. Innovative replied that it was designed to be turned on with an ignition source and I shouldn't have a problem.

I tried searching but I'm not really sure what key words to put in to narrow it down enough.

What is the "Programmable Relay Output"?
This output is designed to control the ground circuit on a relay system. The software is configurable to control the circuit based on 1, 2, or all 3 of the WBC inputs. Here's an example, lets say you have a nitrous oxide system on your vehicle. You would tie the "Programmable Relay Output" wire into the wire that provides the ground for the relay on the nitrous system. The WBC software allows you to define the logic as follows - "if TP is greater than 3v, and if RPM is greater than 3k, and A/F is less than 13.2:1" - then go ahead and provide a ground path for the circuit. If you would like to simplify this logic, you could just say - "if RPM is greater than 3k" - then go ahead and provide a ground path. There are many different strategies and logic available with this provision!
