OR! Build yourself a really GOOD one for $200:

I got my kit from them last week; haven't built it, yet.

Orange, let us know how it turns out.

lets see ~20 bucks for an A/F gauge that works just fine, or 200 bucks for a "really GOOD" one.... ill stick with the 20 dollar one.....:D

a $20 'guage' with narrow band sensor is about as accurate as having someone hang on the back of your car to sniff the gas as it comes out............

oh come on now, it's accurate if you only like reading 14.7:1. But thats if you tune your car for light throttle/load only conditions.

But I guess you could tune your car by putting your head by the exh also...if your face is black after a drive it's too rich, if you have a apex seal stuck up your nose it's too lean :D

that's funny, dude

see just as accurate as a narrow band :)
