Re: Desensitizing GM knock sensors

[Mark Romans <romans@pacbell.net>]

Hi Jim: I am running 24 deg at the high load high rpm part of my map with
11.1 compression and normally aspirated, so just keep taking timing out
until no more detonation.  Then run it against a stop watch with more
advance and the advance with no detonation.  See if it is false detonation
or not.
