Jay,

I agree, and am glad I took your advice earlier this summer when I did mine. It
has already paid for itself in troubleshooting dollars saved, as I've been
having episodes of rough running on leveling out. With the monitor, I know it
is the #1 cylinder. Without it, we'd probably still be chasing things that were
easily ruled out with the monitor. Thanks for the advice. BTW, I did the
install myself including moving a few things around on the panel to make it
fit. Took me about 16 hours, about 6 of which was the actual install. A&P
supervised it, checked my work when I finished and signed it off in the logs and
337. The install is easy to do if you have a hole already available. The
longest part of the install is tie wrapping the wires. To help in making the
harness, I used some shrink tubing to reduce the number of ties as well as add a
protective layer over the actual wires.

Just an update - flew a 2.5 hour break in flight today (Longmont to the
South Dakota line and back). What a difference. 5-8 knots greater IAS,
better climb with lower MP settings, and just a better feel - kind of more
solid feeling in the vibration. Of course, all of this might be
rationalization for a 5-6K bill...

Michael, I highly recommend adding a little (in aviation terms!) to your
bill at this time, and add a multi-channel engine monitor to your panel.

When we put in our rebuilt O-540 last year, I considered it a "must have".
As opposed to the old single-channel EGT/CHT meter, our JPI EDM-700 enables
us to graphically monitor each cylinder's performance in real-time, and
allows us to adjust mixture and throttle settings in order to equalize
temperatures between cylinders. It also gives precise oil temperature and
fuel flow information.

Compared to the cost of an engine, the cost of installation is
insignificant.
