A/F Ratio Gauge

If the Halmeter is connected to a narrow band sensor, however, those precise gradations are just wishful thinking. The sensor does not have the resolution to give a proper reading for the display to show.
For useful info, you need both a wideband sensor and a controller/display box. A precise display on a sloppy sensor won't tell you anything useful.

Wait a second... Northwind, what's your question?

I'll repeat what others have said, and what I always say...THEY'RE NOT USELESS! They're just useless for tuning! Lots of things are useful for some things but not others. The problem with these...and I would say ESPECIALLY with the Halmeter, as it purports to give specific information...is that sometimes people believe they are getting something that they are not getting without a wideband sensor and a gauge that works with one (NOTE: Most of the standard gauges will NOT work with a wideband sensor without modification, unless there are widebands that read from 0-1V...I think most of them are 0-5V and the stock narrow band sensor is 0-1V...I'm sure someone will step in if I say something stupid). I've found my "useless" narrowband-Autometer gauge setup to be invaluable in the diagnosis of a number of problems I was having with my car involving open vs. closed loop, etc.

Considering how much the Wideband O2s have come down in price, I'd say splurge a little bit and get one of the wideband kits for ~$350 which are accurate and can be used to tune vs. the $150 for a somewhat effective gauge that can mostly be used to troubleshoot.
Check the group buy section for info on the Wideband setup.

Yikes, who is charging $150 for a narrowband A/F gauge??? And can I get in that business?
I got my Autometer for about a third of that. I would agree that the wideband setup for $350 is a far better deal than a narrowband gauge for $150.

RX7.com has an a/f meter they make thats LED lite up for like a 100$ which is good for a starting kind of meter like that. Who ever is saling those widebands at 350$ is a pretty good deal. Last time I looked at a wide band it was like 1200$ or so I want to say.
