I thought that you had the EM2, but sometimes it's hard to
keep track of everybody's projects.... well, except John's & Rusty's
:-)
The
EM2 really is the better way to go.

Hey, some
of us don't have poopy diapers to change, so we have time for the list
:-)
As for your
EM-2 air/fuel display, does your engine run well at the mid-scale
reading? My engine used to run at mid-scale on the old mixture monitor
gauge, but I have to be at about 8 bars on the EM-2. Tracy says his
runs fine at mid-scale on the EM-2, and of course I believe him, but I've never
been able to explain this.
I did some
testing with a variable voltage source, and these are my
notes:
3-30-04
Checked the old mixture gauge, and found that it lights the first
bar at .33V, the 5th bar (mid scale) at .86V, and the last bar at
1.4V. The EM-2 lights a bar every
.1V, with full scale at 1.0V. This
is supposed to be the way O2 sensors work, but my old gauge worked fine on the
previous engine configuration.
I ran the old
gauge with the EM-2 for a while, and just accepted that my new "normal"
reading is 8 bars.
There's a
possibility that my old mixture monitor gauge was just wrong, but I find it odd
that mid-scale is right where the engine wanted to be. Since you have one
of these, and have the ability to fashion a variable voltage source, would you
test yours to see if the mid-scale reading is similar to the .86V I found with
mine? Since that
gauge has colored markings, perhaps the manufacturer centered the green range on
.86V for a reason. I've thought about scaling my EM-2 down to make
midrange "normal". It's just one of those things that festers in the
back of my brain and bothers me.
Cheers,
Rusty (debating
flaperons on the Kolb
list)
