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?

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)?
