Engine Analyzers

In that case, look at the Epic engine monitoring and control system from
unison. It's got the engine monitor and an advanced FADEC engine control
wrapped up in one package. Not allowed on factory builts yet.

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)

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.

Thanks for the info. Just as an off topic aside, are you based at
Westair at White Plains? That is where I am and I recall a Cessna 1MM
(white/blue/tan). Is that you?

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.

My EDM from JPI works great! I've never looked back. Get the fuel flow
option with it though unless you already have a fuel computer. The EDM
comes with more standard features than the GEM. I don't believe the
GEM comes with voltage, etc.

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.

I'll second very word of that.

How's that Reiff system worked for you? I'm about to go from needing extra
cooling baffles (Arizona) to a engine heater (Colo. Springs). My F33A
already has an JPI-700.

I'm very happy with my Reiff System. I've had it on my Six since 1997. Made it
easy to add the JPI EDM700 last summer...all the CHT wells were still open. The
heaters will get teh engine up to around 50 deg in a few hours with just cowl
plugs on.

No complaints. The install was easy, the product works as advertised.

I'm in TN, so the temps get into the teens at night a few months a year.
For the early morning trips, the engine fires up and the oil temp is ready
to go. (The JPI flashes a warning if the oil is not up to set temp yet)

Ditto the voltage and fuel flow. FF works great with a GPS although you may
have to bump the fuel flow (pressure) because of the restriction of the
transducer. My fuel flow when from 25+ at sea level to 22. After adjusting
the pressure, we were back to good flow at takeoff and climb.

The voltage is redundant with a panel gauge but the alarm feature lets you
know if the alternator drops off. You will quickly add the JPI to your
normal scan.

I have an EDM-760 and am quite happy with the unit. When you do your brand
comparision be sure you are comparing apples to apples. Ensure both units
have memory and the same probe sets. Also, shopping at a show such as
Oshkosh can save a lot of money. I got my unit for 60% of the list price by
going between vendors and seeing if they could beat the other guy's price.
I ended up buy from Pacific Coast Avionics, whom I highly recommend. At
Oshkosh, JPI was also throwing in free additional probes. I got sets for
oil, TIT, and a second TIT readings.

When you get the unit make a habit of dumping and analyzing the memory. If
you know what you are doing you can see things like exhaust valves and plugs
going bad many hours (and dollars) before they make their appearance known.
