Desensitize the knock sensor 94/95 LT1

[steveo]

you don't really have control over when knock counts occur but you definitely have a control over how they're interpreted

if it occurs in a narrow-ish RPM band i'd reduce ignition advance in that region to safe-ish levels and zero that area in the max knock retard vs RPM table.

if it occurs in a wide area, then disabling the entire system is usually what i'd do.

as far as a hardware solution, i'd suggest passive filtering on the sensor itself rather than hacking the knock module. if you can identify the frequency, a notch filter isn't that hard to build.

headers setting off the knock sensor isn't really a problem i've had unless they're smacking the frame, usually valvetrain changes do it to me.

Passive filtering. I suspect this would be how to wire it up.

around my area we usually only have 91 octane. i found a station with 93 so i filled it up. im running the stock timing tables too.
the car has 209k on it but doesnt make any noises. ill see if i can post up a log.
