Electromotive uses a cam wheel for sequential fuel injection as I understand
it.  Their ignition system is extremely powerful and effective, they are
great units.  The Haltech E6S-8 (fuel & ignition) has 5 outputs also.  If I
used 4 for ignition it would only leave me one for fuel  Ideally I would
have 4 for ign, 4 for fuel, 2 thermofan outputs, 1 ignition kill, and a few
more things... As it stands I did 2 for fuel, 2 for ign and 1 thermofan and
I am all out!  Honda must use that second cam sensor for something else....
VTEC?

  The S2000 has two cam sensors (one three tooth wheel on each cam) plus a
crank pos sensor (12 tooth wheel).  As far as I know this is how it works on
all the other Honda DIS systems (Accord, Oddysey, Insight, Civic....) as
well.

  For my Civic motor however, I will use a cam sensor wheel which luckily
enough I can purchase as a bolt on from Electromotive.  Not sure why
Electomotive uses a cam wheel instead of a crank wheel as their own system
for the Honda uses a wasted spark system (must just be easier to package on
the car) As for having four output channels for the four coils, the Haltech
ignition box has 5 outputs, so all four coils will get separate signals no
problem.

    The cool factor VERY high indeed.  I am thinking that there has to be
some kind of sensor to tell the CPU what plug to fire.  maybe off of the
alternator?
