What A/F Gauge do you run

I told you why not. That unit (as do all wideband sensors) must have a controller, it just may be inside the gauge. So if you got one for that money that does NOT have wire outputs, you are getting had.

My kit, photo of which was posted earlier, does everything that thing does AND is programmable, AND has wire outputs AND costs less shipped to my door.

The kit I got came with O2 sensor, the bung, LC-1 controller, software, and digital display for under 160 bucks.

Different animal, dude. The gauge I showed is AN-A-LOG readout or at least an analog interpretation of digital data.

But for arguments sake, I guess you're right. Regardless, I still like that one the best and wouldn't want the one that looks like a clock radio. I personally don't need to mess with programming, input/output and such when dealing with my carburetor.

I don't claim to know everything.
