Im curious what one is... I know they're $$$ but the local dyno shop has one and once I get the car close to being dialed in, I figured I could go record some better data and then burn a chip Thoughts?

The stock one in your car is a switching type, all it's meant to do is switch from rich to lean at 14.7:1
A true wide band will read AFRs from 20:1 to about 10.6:1.
There was is a DIY version that while not lab grade used a $3 Printed Circuit board, $12 worth of parts, and $130 sensor. Uses a DVM for reading the output. Not fancy but functional.

A WB is a tuning aid just as an EGT or G-Tech is. Using the right combination of tools is the name of the game.

You still have to figure out what AFR your engine runs best at, there is no MAGIC AFR, it's still about testing, dyno will get you close, but you still have to final tune it.

 

It has all the info.
