Do you have an engine monitor? Which one? I haven't studied them too much
but am interested.

There's been lots of discussion about engine monitors already but on my
Aztec I have a GEM. (I'd hate to support JPI so it was a fairly simple
decision.) I have not gotten it approved as primary (except for outside
temperature) so I still have the old (next to useless) indicators too.

It's a wonderful tool. I'm trying to debug an intermittant problem in
one of my engines right now. It would be almost hopeless without the
monitor.
