Wide Band Air Fuel Guage

There doesn't appear to be any data-logging capability with the item you listed.

That's going to be pretty useless for tuning unless you're able to photographically remember what RPM you were at, what position the throttle was in, and what the AFR was at that RPM.

I for one, cannot remember all of that information as I'm driving down the road while trying to reference my RPM and AFR.

It would be good for letting you know (approximately) whether your tune is good or not but not much good for the process of doing a tune.
