My erratic mixture monitor was one of the stand alone mixture
monitors that Tracy sells. And I must point out that while it was somewhat
erratic it was still very useful and I feel that a possible contributing cause
is that I have it located 12" downstream of the turbo where the temps are
possibly too low for the O2 sensor to work properly.
Thanks. As I
mentioned, my old gauge did the same thing before, but just worked fine the next
day. I never knew why. I'm probably going to pull the FJO wideband
O2 unit from the RX-7 this morning, and temporarily hook it up in the plane for
tuning. If it works really well (and I know it will), I'll probably
install it permanently, but probably not until I burn most of the 100LL that's
in the tank. The 5 wire O2 sensors are about $170 each. It has a
much wider range than the typical O2 meters, so it will still show a useful
reading when there are no lights on the normal
meter.
Unfortunately I've not yet run the engine with the EM2 to see how the
O2 sensor behaves. After I returned from tech school, I began playing hockey in
a beer league again and we are in the middle of our playoffs, so after the beer
& hockey I try to stay away from the workshop :-).
As I recall, you were
recently beaten by a bunch of girls. Did they out drink you as well
:-)
Cheers,
Rusty (there's always
curling)
