Tanis Pre-heater with Engine Analyzer

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.

Should have gne this route, not the Tanis route.

Amen. Ben' there, done that!

Reif is a LOT easier to add.

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.

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.
