o2 sensor hook-up

[Bill Shaw]

Hi guys,

I just installed the o2 sensor in my exhaust for my efi conversion.  I
don't have the ecu installed yet,  and it may be a couple of weeks before I
get a chance to install it.  In the mean time I'd like to hook it up to a
display to see what the carb's doing to the a/f ratio.  I saw a posting a
couple of weeks ago about supplying a .5V bias to the sensor.  Do I need to
do this to get a reading from the sensor?  What kind of a supply circuit do
I need? Or is the o2 sensor generating a voltage that I can just feed into
the display?  I'm using the Intelitronix LED bar graph a/f ratio display
from JC Ripme. Same circuit as floating around here, but it's packaged real
nice.  It's worth the $40 for the clean packaging, IMHO.

Thanks,

Bill
