I believe it is the Saab DIS... which uses a secondary spark after ignition 
to check ionization within the cylender, and to tell a whole bunch of 
differnet things (knock, pressure, rich/lean??,etc).. each coil- on - plug 
pack houses (or so i've read) a capacitor that is used for the secondary 
spark.....

I am also working on a dis system, although do not know enough as of yet to 
set anything up (which is why i am on this mailing list, trying to learn)... 
but am definitely planning on running separate coils (for each cylender) as 
the motor is a 5 cylender--
