Was going to do some auto tune in the air
yesterday, to get to some regions of the performance map that can't be reached
on the ground.
Took off and the O2 sensor indication completely
disappeared from the EM-2 display. Did one circuit of the airport and
landed.
Discovered that the O2 sensor had failed
(physically -- the top fell off and separated from the body). This caused me to
raise the following questions.
1. I believe that the oxygen sensor readout is only
that, not used by the EC-2 for control purposes.
2. When in auto tune, is the EM-2 looking at the
sensor for indications of which way to adjust the mixture? If not, what is the
feedback mechanism?
I went to the Auto parts store for a replacement,
and ran into the problem that there are 100's of different oxygen sensors, and
they need to know what car it came from. Anyone have the specs on what this
sensor is?
