Tuning O2sensor Knock Sensor Engine Damage

[bruce plecan]

Well thought I just had one to go, #$%^&*(, talking too
much and remembered a couple details.
Preventing Engine Damage:
The problem with totally reling on a Knock sensor is that it is
tone deaf.  It is designed to look for a particular range of noises
and completely ignores some.  With a SBC that is usually in 
the 2,000 to 2,600 rpm range.  Soo at 6,200rpm I would not
beat the cost of a new engine on that.  Also I have not seen
anyone guarantee in writting that there are no secondary
harmonics that might dampen the tones the knock sensor
might hear at other rpm,  TC, I would invite your comments
on the above.

Also remember the O2 sensor is usually on one cylinder bank
so IF one injector fails on the opposite cylinder bank it will
never show.  I have seen one driver spot a bad injector at high
rpm, but if he was at a lower state of tune it would have gone
undetected.

                   does it make a sound???....
