Ken,
Thanks for the input. I eventually figured out the hose question with a
little applied logic that I apparently wasn't capable of at the time (after
midnight). The hose is to be removed from the vent tower and the hose is to
be plugged. This is to prevent gasses from the crankcase influencing your
adjustment results. The same reason you would want to change your oil
before getting your emisions test. Wrapped everything up last night and was
getting good numbers on my voltmeter and your gauge. Went for a nice long
test drive and got satisfactory results. Was also able to see that I'm not
experiencing a lean out under load. Although I have no long hills to test
on I simply floored it for the better part of two miles approaching 80 MPH
and stayed full rich the entire time. I'm also getting very good
acceleration off the line. Our trip next weekend will give me an
opportunity to see how it's handling hills.
Thanks again for this wonderful little gizmo.
Jeff

Jeff;
I do not remove the hose when setting the mixture. I say adjust
the engine in it's normal configuration. This is how I do it before
heading to the vehicle smog inspections:
1> drive the car until hot.
2> turn off engine and disconnect O2 sensor from ECU but leave monitor
connected to sensor.
3>start engine and adjust AFM spring to get O2 output near center of
range. Use the allen socket screw to fine tune.
Of course do all this last, after timing and throttle body adjustments
per Bentley. As for CO, I guess I have always been lucky.
Good Luck and Drive Safely

Jeff Warner spoke thus....
....I temporarily installed your O2 sensor last night in the engine bay.
Very
nice little device. I had to go back to your website (

was
in
fact looking at the gauge upside down.
