What are the advantages of going to a wide-band O2?

My MS2 runs really well on it's narrow band sensor, but I'm always looking for better and smoother control. I'm thoroughly confused on if the wide band is worth it, and how to hook it up. I've read thru the forums here, appears I'd need some controller for it.
Any ideas on this? THANKS!

If you're not using a cat. you'll spend very little time at 14.7:1 - so a wideband is very useful.
You do need a controller as MS can't use one directly. Most will also give a simulated narrow band output - so you could stay with narrow band control, but see what things are doing at other times.
I've got a Tech Edge unit which is available as a DIY kit. Gives more options of sensor makes than some others.

I'll look into that. How will it affect daily driving and idle smoothness? Sometimes while idling, the RPMs pulsate a bit. Up, down, up, down....

You can set up MS to only use the wideband output under the conditions you decide. It would not normally control MS at idle. But it would show you if the mixture was changing at idle.
