Yea, You can get them from Summit and some of the other speed shops. HOWEVER, they're not accurate at WOT (something they don't mention in the ads). Those sensors are 'normal' narrow-band sensors which are only good for tuning part-throttle conditions. For WOT tuning, you'll need a wide-band sensor. There are kits, but they're very expensive. There was a post a while back about a do-it-yourself setup, but that was still around $200 plus you'll have to solder the board together.

I have a Edelbrock unit from summit. Cost $129 and comes with a bung that any muffler shop can weld in and a nice dash mounted display. I also saw a post about a guy who had a wide band and a narrow band and really didn;t notice much different in there readings. He sold the wide band and kept the much cheaper narrow band unit. I like mine.

I just put the Autometer setup on my car. I don't know about the accuracy but it is very interesting seeing where youare in A/F ratio under different driving conditions.

A stock O2 is ONLY a rich/lean switch. It ONLY knows 14.7:1. 850mv does NOT equal 12.x:1 AFR on a regular O2. Temp and pressure changes what mv equals what AFR. 850mv could mean 14:1 or 11:1 AFR depending on conditions.
