Mike,
   That is very interesting. I would be tempted to use the device outputs
to first>control an action that would reduce head temperature and
second>sound and an alert when the first does does not succeed.
   Just spit-balling here; you could program a setpoint which triggers a
relay to alters the output of the O2 sensor to (falsely) report a
leaner exhaust. The ECU would then enrich the mixture, cooling the
combustion chambers.
