This is something that
I've bugged Tracy about pretty extensively. Mine does the same thing
yours does, and Tracy says his doesn't. I used to use the old gauge
that Tracy sold, and I've done some testing with it, and the EM-2 both
connected (verified not to interfere with each other). When the old
gauge reads mid scale, the EM-2 is about 7-8 bars. Since O2 sensors
are supposed to put out 0-1V, mid scale should be .5V, so I made a
variable voltage source, and used it to simulate the O2 sensor. At
.5V, the EM-2 read mid scale like it's supposed to, and the other gauge
read below mid scale. From that, I concluded that the EM-2 was doing
what it was designed to do, but I can't explain why my "mid scale"
mixture is well above mid scale on the EM-2. I tried using a new
sensor, of the same type others are using, and it made no difference.
Now that you have me thinking about this again, I just made a note to
"fix" this in the calibration mode.
Good luck. Don't get
discouraged.
