simple wasted spark system???

[James Ballenger]

	There is another way to do this without a cam sensor.  You could
make a home, or sync, signal as a fourth pick up point somewhere in the
wheel and just reference the difference to TDC in the program.  Even easier
is to use a 2 channel sensor and use one of the existing pick up points as a
sync on the other channnel.  Haltech does this and my little 4 banger only
needs 2 magnets because the rising edge of each magnet is the trigger and
the falling edge of the south magnet is the home signal.  Though the cam
sensor would help out a great deal if you planned on going with sequential
fueling later on.
