Barkleydave,. One comment... The coil that was supplied with my old FSI setup has a 4.1 ohm primary. In addition, the FSI instructions mention that they supply a special resistive wire from switch to coil. That would indicate to me that FSI engineers are apparently concerned about the amount of current that the modual they use can handle.
Given that these provide a really hot spark, and don't have to support high RPMs, and are not on an 8 cylinder engine, (so have a low switch rate), I don't really see a downside to limiting the current to the module even more than you have done. But, that's just what I think, no scientific proofs on that.
If you are happy sliding the spark lever around, then the centrifugal and vacuum advances the Honda offers are obviously not for you. The whole point of this topic was to point out some issues with the FSI setup, (centrifugal advance but no vacuum advance), and offer a solution to those in the form of the modified Honda distributor, which gives you both advances. (And it's also a much cheaper option for the machinist capable guys.)
Everybody has their own favorite setup, they all obviously can work. Different strokes for different folks, and that is how it should be. Thanks for posting your Pretronics data, it all seems reasonable to me.
