I've tried a bunch of them, so I gave my reviews. Plenty of people have widebands, and usually they like what they have so that's what they'll say, I have messed with most of them, they all have faults.

I guess what I was saying is that it really doesn't matter what the wideband says. It doesn't matter if it says 9.5 when you're going down the track or if it says 12.5. As long as you know what number equals a proper air fuel mixture on your car, then you know what number you should be aiming for. I think regardless of whether you are carbureted or fuel injected, you should tune your car first to have good plug readings. After you get your car tuned and your plugs look good, then look and see what the wideband number is. From that point forward you will know what number you are going for. People tend to read on the Internet what others say their air fuel mixture should be and that's the number that they shoot for without really knowing if that's what makes their motor the happiest. Not to mention all the variables between widebands, sensors, and location of sensors. A wideband will just get you in the ballpark, you still have to go old-school and pull your plugs if you want to fine tune. I also believe a wideband is a waste of money without a datalogger- but I guess they look cool on an a pillar when you're out being fast and furious.
