Started, AFAIK, in Formula 1 by the Honda team in the 60's.  A bit crude.
Lay your hand on each exhaust pipe [one per cylinder] and the temp tells you
who's running rich/lean/etc.  A bunch more sophisticated since then.
Individual temp probes when setting up an engine and infrared readers at the
races, I think.  Drag racers do it as well, I know.
