    you can use some widebands for every day driving
    some can be set up to mimic a narrow band 02 sensor

    there is no detriment to leaving the WB in place. I run mine in there all the time, but also run OLSD permanently so check there is nothing 'funny' happening by glancing at the WB. As tokymon, you can program the WB outputs to mimic a NB and use this to trim the fuel as it mimics a normal stock O2 sensor. But other than that the WB has no active use in fueling. Interestingly, more modern cars now run WB to adjust fueling as this is much more accurate than the NB and they achive more MPG. I've yet to test the theory trying to get ecomony out of the camaro as I somehow keep putting my foot down which obv kiss the eco run, maybe I shouldn't have made it sound so good at WOT hahah

    You can run the wideband anytime...

    you just have to be careful while tuning (make sure trims are not correcting ahead of you/wideband);

    but you can certainly run the widebane every day to monitor if CL/trimming is trimming properly, and to see if there is any deviation on tip-in or tip-out.

    Some widebands like the LC-1, as was said above, have an output for providing a narrowband signal that the PCM can use.

    I'm getting an LC-1. Seems like everyone loves that one.

    When you get the LC-1, bench test it before installing it.
