engine monitors

[Rosspilot]

I am considering installing an engine monitor in my Skyhawk . . . and have
narrowed the search to these two selections:

Gem610 and JPI EDM-700

Any pireps, recommendations, anecdotes, or other feedback?

Thanks in advance . . .

I have EDM 700's in my Extra and Baron, and they work great. Aviation
Consumer had a review on these, and based upon their recommendations I went
with the EDM. You can check out their back issues online.

I was looking into this also. If you do a google search, you'll find a lot
of information.

EDM 700.
You can download the data after each flight and plot it using a spreadsheet.

Although I'd probably pick them, I just heard that EDM changed their data
download format to restrict its usage to only their proprietary software.
They wanted to keep one from using others, such as "EGT Trends".

Anybody else heard that or know why?

I have this in my Skyhawk and love it.

Not exactly. You can still down load it and look at it with a spread
sheet, however they would be very happy to sell your their tracking
tool.

EDM 700 works great for me. Just upgraded it with fuel flow - very nice.

I looked at both of these and went with the JPI due to it's far better (more
better?) usability and functionality.

Hi Rosspilot

I'm interested to know why you eliminated the EI analyzer from your list.
It is a great piece of equipment from a great company.
I fly the same plane as you and my EI monitors all 6 CHT's, all 6 EGT's,
Oil temp, carb temp, and I still have room to add another probe -
currently considering outside air temp - I don't think that fuel flow is
all that beneficial - I know it's about 8 GPH and yes I do check the
caps to ensure that they are not leaking (once bitten . . . )

If you haven't checked it out, don't discount it

Thanks, Tony . . . looking in to it.

I will not consider any JPI product because of their despicable behaviour to EI
some years ago.

I've had both and prefer the EDM 700 for the download capability and extra
features such as voltage monitoring. Yes, you can monitor your gauge but
with the EDM alarms set at your less than ideal voltage, why add another
instrument to your scan when one will do.

Also, I do not believe you can get integral fuel flow w/ JPI.

The sales info about the probes seems like hype. But I have had good tech
support from both companies.

FWIW, {|;-)

I'm unaware of this. What did they do?

I just got another report from a friend who has the JPI but said it comes with
cheap (and innacurate) washer-type probes that fit between the plugs and
cylinder heads . . . said the better probes are the screw-in types that go in
the pre-drilled holes on the head . . . recommended Tanis probes. Said once he
put those in, the JPI was perfect.

Yes, you can. It will appear in the lower right portion of the display
next to the temperature.

The other company (IIRC, it was EI) had a product on the market called
"FuelScan". It was trademarked. One of the features of the JPI unit is it
operates as a "scanner" (no trademark), and this was documented in their
literature.

They decided that they didn't like the competition from the other firm, but they
really *did* like the product name. So they filed a trademark infringement suit.
Never mind that it was the *other* firm that held the trademark.

The other company could not afford to defend the suit. Now JPI sells the "Fuel
Scan" and owns the trademark.

Ron Natalie probably remembers more details than I.

The spark plug washer probes are not inaccurate. You will always
read a higher temperature at the sparkplug than at the screw in probe
location because the temperature is really higher at the sparkplug
location. The sparkplug mount will also respond faster since there is
less mass of metal from there to the fire to slow the response.

If you don't believe this take any brand of thermocouple meter and
make two thermocouples out of the SAME length of thermocouple grade
wire and mount the thermocouples at both locations then measure the
result.
You will also find that the "piggy back" mount where you already have
a screw in heater or a factory CHT probe at the probe hole mount you
will read several degrees lower. It is basic physics 101.

I have a EI scanner and I would not buy another one since the EI
scanner I have requires a UNGROUNDED thermocouple probe. I have to
replace an EGT probe every year or two since oil wicks into the probe
and forms a conductive carbon path to ground. This will cause the EGT
reading on that cylinder to read higher than it should. This can be
verified with an ohm meter.

EI may have changed the design since I bought mine but DO NOT buy a
scanner that requires UNGROUNDED probes or you too will be replacing
probes every year or so because no matter what they say about how well
sealed they are the probes will wick oil and ground out.

I've had the edm 700 in my skyhawk for a few years and it's fine. My only
gripe is that the engine data can only be downloaded to a Palm or laptop.
It doesn't download to a Pocket PC, which I happen to have.

How does the "fuel flow" option work? Where is the sensor and what does it
measure?

It's a paddle wheel-type transducer that is cut into a fuel line. It measures
actual gallons per hour.

I bought that option on my EDM 700 and I'm glad I did. It is quite accurate;
if it says I've burned 40 gallons, the pump will say 39 when I top off, a
2.5% error. The unit has a software "K factor" I could change to tune that
out, but since it errs on the "safe" side I haven't bothered. I'm blessed
with one of the few Cessnas that have accurate fuel gauges, so I'm able to
cross check them with the EDM 700 and vice versa.

The fuel flow reading is also a useful leaning tool. I know the fuel flows
for my typical altitudes and power settings, so there's no hunting around
with the mixture control when I level off in cruise.

The EDM 700 is also RS-232 interfaced to my B/K GPS, so I get nmpg, range,
endurance, etc. on both units--very cool.

I think this is just a rumo and nothing else.

If you have to choose a moitor: EDM rules!

I got the EDM 700 with FF -> GREAT and very good service from JPI
