Does anyone out there have experience with having installed a tanis
heater when a engine analyzer is already in place. I have a JPI Classic
Scanner (EGT/CHT) that had bayonnet-type probee for CHT. Tanis has a
kit designed for this sitation, but after we installed the kit, none of
the CHT readings worked at all. The installer called Tanis and JPI and
did get very useful advice on what may be going wrong. Has anyone out
there faced this problem (and successfully overcome it)?

The bayonet probe showed 40-50F higher than the other probes on my airplane.
It was very annoying. JPI could fix it quite easily by modifying their
software to adjust the reading for bayonets, but they do not. That is my
opinion.

On mine, the Tanis kit had us swap out the bayonet probes for some sort
of rings that fit around the inserts that go into the CHT probe slots on
the underside of the engine. Now all of my probes read non-sensical
numbers like 980 degrees F and they fluctuate wildly.

980F is obviously not right. In my previous e-mail I said "bayonet" but I
actually meant the spark plug adapter type. The spark plug adapter type were
way off. Did you check you have JPI compatible probes?

The installer supposedly called Tanis and JPI so I assumed they check
for compatibility. I am not sure how I would independently check this
myself. -sami

Get the part number off one of the probes (follow the wire to find the
label) and call JPI tech support.

My understanding is that you require the TAS100T-K probe from TANIS. It
interoperates with the JPI system. It looks like the standard TANIS probes,
but has the CHT sensor built right inside. There are four wires coming out
of each probe, 2 for the TANIS, 2 for the CHT. Unfortunately, each probe
cost $170 US. I just bought the JPI700 for xmas and have purchased the set
of TANIS/CHT probes as well. Need to get a little warmer here in Ottawa
before I can get to install the stuff, so I can't tell you how well it
works. I read lots of stuff regarding the "spark-plug" thermocouple and all
indications say that they don't work well.

I have a Tanis heater and a JPI EDM-700 on my 182Q.

The JPI CHT probes are bayonet style except for cylinder 3. Cylinder 3 has a
JPI washer-type thermocouple under the top spark plug. Consequently, it
reads lower than the others. The bayonet socket for cylinder 3 is occupied
by the original Cessna CHT probe. JPI makes a dual bayonet adapter which I
intend to install sometime.

The Tanis has a pad heater on the top of the block and on the bottom of the
oil pan. Each cylinder has a Tanis heater/gasket under the rocker arm cover.
The system works very well.

Should have gne this route, not the Tanis route.

I did, and I used the Tanis heated intake bolts, instead of the CHT probes,
which were being used for my Insight GEM.

I have both the Tanis and the JPI (mine is an 800 model). The
installation originally had the spark-plug ring type thermocouples and
I found them to be terrible. Wildly divergent readings. I bought the
combo thermocouple heater elements and thermocouples from Tanis (from
memory they are the TAS-100TK) and they have worked just fine. The
only problem is that two of them have failed in twelve months. That's
a bit annoying at $170 a pop.

Amen. Ben' there, done that!

Reif is a LOT easier to add.

Just FYI, I went through CHT-probe hell awhile back and ended up with four
spark-plug probes on the cylinders. In the summer, I have a bayonet probe that I swap out
for the heater on #3 (4-banger). The bayonet (the official place to measure CHT, BTW)
reads at least 60 degrees *colder* than the spark-plug probe. I've seen two posts here
that tend to imply the opposite.

It's an issue for me, since in cruise I typically see about 400 degrees on the
spark plug type... a bit too hot if it were true. Since it's actually 350 or less on the
"real" probe, I'm not concerned about it.
