Engine Analyzers

I am seriously thinking about installing an Engine Analyzer in my
plane and am looking at options. I think I have narrowed the choice to
J.P. Instruments or Electronics International. My mechanic has more
experience with JPI and feels their probes have a longer life. My
research has me leaning slightly towards EI for price, function and
design features. Really I am on the fence and am looking for something
substantive to sway me. If it matters, this will be installed in a
1999 Seneca V with Continental TSIO-360-RB (220HP Turbocharged)
engines. Does anyone have any experience, recommendations or
suggestions? Maybe I should do 1 of each (just kidding).

I put a EI UBG-16 in my Skylane in 2000. (6 chts, 6 egts, oil temp,
bus voltage, alternator load current). Works great, no problems with
probes.

Biggest technical challenge was getting the brightness of the display
to track the main dimmer bus.

It sure shows what a ****TY job Cessna did when they "designed" the
cowling/baffling in my L model Skylane. I have improved the cht
balance greatly with some added baffling. Front two chts are still
40 deg F colder than the back four.

It also shows how POOR the mass-flow balance between the front and
rear cyclinders is on the Continental O470R. Due to the brain-dead
induction plumbing, the front two cyl get much less fuel/air than the
other four.

That's what convinced me to get a GEM (Insight). I've been quite
happy with it.

*Do* get an engine analyzer. They're a good investment. My plane
just came out of annual when I flew it to PJY last month. On the
descent, I noticed that both temps on one of my cylinders had
dropped.

With some great help from Michael, I learned that both plugs had
fouled. I'm sure I wouldn't have noticed it without the analyzer.

I put one of the EI boxes in my 182 in '93. It was the older
style...not a graphic display. It worked well and was worth the money
spent on it. Over about 500 hours I replaced 3 EGT probes. Customer
service was great, I'd call and order a probe...it would be in Alaska 2
days later...about $80/probe.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.

Hi,
I have had a Insight GEM in my Maule for the past nine years. no
problems with the unit. It did help me locate a bridged plug quickly though.

My JPI EDM-700 has been flawless for the 18 mos. it's been in the
airplane. It has the fuel flow option which I highly recommend. An
engine analyzer is a great trouble shooting and mixture setting tool;
I'd hate to do without one now.

Had both (now have EDM JPI-700.) Check out JPI's new series (legal
replacement for steam gauges in a few planes.) I like the operation of the
JPI better. User interface seems better to me, FWIW.

Had good support with both. Although, I did have to replace two probes from
the EI.

If you need (or plan) a block heater, get this sorted out beforehand. The
EI or JPI probes will need to co-exist with the CHT/heater probes. For this
reason I have a Reiff system (bands, no probes)

If you put LASAR ignition on, you'll also need to share the probe port with the
CHT probe for the LASAR controller, as well as if you have a factory CHT, you
may need to keep that in it's probe well.

Thanks for your input and I like JPI too. But, what I need costs over
$5,000 and that's a little hefty when you consider that Rocky Mountain
Instruments, a very reputable company with a good track record, provides
quality monitoring for much less money. Of course, the system I would be
purchasing is for an experimental.
