I hear you, but the closest thing I could find is the
Link ECU at ~$800 and that will do individual coils on
a five cyl.

You need the APC ECU, a knock sensor and an LED.  The
ECU can be hooked up to flash an LED when it detects
knock.  It works pretty good, and will flash before I
can hear the knock.

Try it out, but I have a you'll want to put the MC
ignition back.  Hopefully you still have your flywheel
with the timing pins?  I should have said that I would
have tried a MAC-11 if it didn't involve putting a pin
in the flywheel.
