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 :-) S.
