David, I don't fool around much with Digijet though I may start to since
I recently got an 85 (an engine conversion is more likely). The TempII
sensor for the Digijet is the same one as for the Digifant in Syncros.
In circuit with key on it reads about 1 volt at cold engine and .3 volts
at hot engine, Digifant.
