Not a clue... Jon Lusky seems to have quite a bit of expertise in this area

You would probably be better off with the O2 sensor.. Unless you are
monitoring at each cylinder, you will get an average temp... One could be
running at 1800 deg, while 7 could be at 1000 degrees... The one will melt
something, while the others are too rich.  The O2sensor would catch this a
little sooner IMHO
