Re: Air Fuel Mixture Gauge?

["Christopher P. Locke" <d.locke@snet.net>]

An a/f mixture readout meter is a really handy tool.  I built one for my
car, but i haven't installed it yet.  I don't know as to the accuracy of
the JCW one, but what can you expect for $35 and from JCW???  Mine does
real time, has an input impedance of over 500 Mohms, and uses a coax
(RG174) to keep the 02 sensor line clean from foreign electrical noise
from an "antenna" attached to the sense lead.  Parts cost me about $.05
(ok, maybe a couple bucks) and i got to make the box that holds the
parts.  i use it as a test tool now, since it isn't mounted in my cabin
yet.
