Thanks.

Hi Sal,
I also have been struggling with this idea, to convert to a more modern wasted spark system or MSD for the same reasons you have. I have come to the conclusion that such a conversion would be too complicated and too much trouble in light of the fact that the stock DME ignition is more than capable of firing at all rpms but is limited by the ignition cables, cap and rotor which are not high energy capable.
Since the weak link in the Carrera ignition is in the secondary side, it would be much easier and most cost effective to concentrate your efforts there so your engine would be able to take full advantage of the DME ignition potential which is not limited in any way by the coil not having sufficient time to charge. This would mean converting to HEI ignition cables, cap and rotor that would enable your system to fire your spark plugs gapped at 0.060" consistently from idle to redline and never having to worry about it again.
All I can say is that converting to a complete HEI system on my secondary side was probably the best bang for my buck from a performance upgrade perspective that has enhanced driveablity in all rpms. If you took this route I seriously doubt that you would feel the need to pursue more exotic solutions.
By the way, the wasted spark or coilpack ignition system also requires the use of HEI ignition cables (and so does MSD) but eliminates the need of the HEI cap and rotor.
Cheers,
Joe
