RE: ignition module

I don't know how much this will help you cause I don't have the exact
numbers and pinouts off the top of my head....module aks as a filter and
amplifier for the piezo(knock sensor) Each block and valvetrain
configiguration requires its own filtering...the output to the ecm rises
from ~3 volts to as much as 11 volts depending on intensity of the knock.

p.s. yes I know how to spell acts...just looked funnier when I spelled it
wrong first so I left it.

Does anyone know much about the GM ignition modules that were
used on about everything, like the Sy/Ty and the corvette?  If so, let
me know because I need to know how it operates and at what
voltages.  I am in the process of making an ignition module that will
use a HALL effect sensor instead of a reluctor.  Any ideas would be
helpful.
