I recently got my wideband setup up and running (thanks to everyone
involved).  I do not have an O2 sensor in my old car, so for now I'm
inserting the O2 sensor in the tailpipe.  The unit warms up in about 15-20
seconds (added a few resistors to the ceramic 1 ohm resistor), and shows
4.00V +/- 0.02V when warm.  When I insert the sensor, readings tend to
fluctuate quite a bit.  For example, I have several exhaust leaks from bad
gaskets.  The readings via voltmeter fluctuated from roughly 2.50 - 2.70,
with 2.60 appearing to be the average voltage.  After reading saved emails
from this list, this appears to be normal.  Does the LED meter help in this
regard, or does it fluctuate normally?  Or, am I doing something wrong?

How do you guys get usable output?
