Wide Band Logging today :)

Since I have true duals it would work perfect for me. As it stands I have three O2 sensor bungs on my exhaust: Header(stock narrow band), and one on each pipe about 4' down the line(for heat issues to be minimized).

NTK sensors and heat sinks. I'm yet to get a sensor overheat message.

I don't use heatsinks and have yet to have a NTK go bad. I even bought a new NTK to compare with the one that's been in there and there is no difference. It's the OTHER sensors that have heat related problems. Just an opinion. Take it or leave it. Narrow bands suck. Sorry, couldn't resist saying that.
While not real keen on bright shiney gauges, it seems to me you'd want a display to look at out of the corner of your eye at least, when checking out some change you've made in the engine. At least you can back off right away if you see some 14's, but if you data log on a computer, it SEEMS you'd only be able to look at the afr after the fact (unless someone else is staring at the computer).

The heat problems just cause errouneous readings for wankel7's NTK. This isn't a "oh i think i'll have problems" this is a "I've seen heatsoak issues affect NTK sensors" problem. I have a Bosch LSU 4.2 Sensor myself but I doubt i'll have problems with it.

I don't like the bosch sensors. They're cheap, not as accurate, and in my experience, don'tlast near as long. That's why they are 1/4 the price.

I'm just now working on some new logs that I got from the night at the drag strip last night.
I was able to start bringing the fuel curve back from the brink but I didn't really feel too much of a difference in the car's pull.
Btw- does anyone know of a place that has(for download) the old win98 or win95 excel? I could sure use it to edit files on my laptop rather than having to transport all the files over each time I log to clean them up.

But, for the final tuning, to get the car really dialed in, datalogging is the way to go. Helps with correction maps, and also helps with those tricky map points that are more difficult to maintain on the street.
Here is a datalog of mine (tuned a little rich for Scathcart's liking, I know )
