Anyone have experience with Air/Fuel Guages? Options

[dcruiksh914]

After it was suggested that installing an O2 sensor and Air fuel gauge would make tuning a much easier and more accurate task, I got the stuff and went for it. I got 2 O2 sensors and 2 gauges (one for each exhaust bank), and installed. I used the 3 wire sensor as I had read that the 1 wire needs the heat of the engine to get it going. So, everything is in, and it doesn't seem to be working, or I've got a strange problem. The gauges, which have a five bar LED readout ranging from Lean to Rich, suggest that I'm running very lean (just one bar lit). Sometimes, that bar goes out and I get no readout at all. I can adjust my A/F mixture screws all the way out with no affect at all on the gauge reading. I know my car has been running rich, so if anything, the gauges should be indicating the extreme opposite. I called the Summit tech line, and they said that I have everything installed correctly and it should work.

I'm running a 3.0SC engine with webers and 916-6 factory heat exchangers. I placed the O2 sensors about 2" down from where all three pipes come together.

This seemed like a great idea, but now... (IMG:http://www.914world.com/bbs2/html/emoticons/pinch.gif)

Anyone have any experience with doing this and any thoughts about what's going on here?
