The only real problem I had
was that the O2 reading in the EM-2 seems erratic. Todd, did you ever
figure this out? Mine was so wishy washy that I couldn't confirm whether a
longer "bar" means richer, or leaner. I swear sometimes it would go one
way, and some times the other. Finally, it just went to no bar, and stayed
that way. I can't say that I can blame the EM-2, since my old
meter did the exact same thing once. It just refused to work one
day, then worked fine the next. Maybe everything will just work
perfectly tomorrow, and all will be well. I have to admit to being tempted
to take the FJO wideband O2 meter out of the RX-7 for use in the plane.
That would be sweet. Fast, reliable air fuel reading from 10 to
20.
Hi
Rusty;
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.
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 :-).
Hopefully I will get it done soon so I can get it back in the air. Somebody
(Steve Brooks?) was asking questions about the IVO. As I'm using a
76", 3-blade IVO with electronic governor. I can possibly give some
answers, but my previous data was somewhat limited as my instrumentation was
very limited. With the new panel with the EM2 & Dynon, I will be able to
give much more definitive performance data.
As soon as I heal up & sober up :-)
