Wideband function for a daily driving is typically not recommended for several reasons. One, a wideband sensor is much more expensive than the stock narrowband and therefore you wouldn't want it to get damaged/dirty through daily usage.

Two, the driver to utilize the new hardware; in this case, a wideband O2 sensor, is not there. You can hook one up and install it in place of the stock sensor, but you probably won't be able to get it to run in conjunction with the stock ECU. Maybe you can modify it to make it work, I don't know.

Third, during acceleration the ECU is thrown into open loop mode; that is, it doesn't check with the oxygen sensor to determine the right amount of fuel; it derives the numbers from preset maps in its program. So even if you had a wideband working in there, it wouldn't be used anyways.

Widebands are only used during dyno tuning sessions, and in this time fuel maps are created and set into the ECU's program through chipping. In theory you could get that wideband and set the ECU on closed loop forever; you'd never have to tune, no matter what you did. But in real life this is simply not the case.
