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.

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)?
