Tanis Pre-heater with Engine Analyzer

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.

Regards,
Ken

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

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

980F is obviously not right. In my previous e-mail I said "bayonet"

I
actually meant the spark plug adapter type. The spark plug adapter
type
were
way off. Did you check you have JPI compatible probes?

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.

The bayonet probe showed 40-50F higher than the other probes on my

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.

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)?
