This is what I don't understand ..

1. A DIS has two air gaps; one for each spark plug.

2. A Distributor also has two air gaps; one for the 
  active spark plug, and one in the distributor.

Seems to me the DIS is the better option mainly because 
it has the inherently more accurate crankshaft generated
reference signal(s).

Thoughts?  Peter.
