Direct ignition=no distributor.  One small coil per plug, the ECM fires 
them directly instead of a larger coil that goes thru a distributor to get 
to the plug.  It can also be set up as a wasted spark system, with one coil 
per 2 plugs.  Both plugs fire when the coil is triggered, so care has to be 
taken to select cylinders such that one needs to be fired, the other is in 
the exhaust stroke.
