I had similar thoughts, but one of the main advantages of going with COP is that you can avoid the mechanical reliabiliy issues with the distributor cap/rotor setup.

Staying with a mechanical design, the best he could really do would be individual coils per cylinder. A controller would be needed to do away with the cap and rotor and just use the trigger wheel.

True you do lose a lot of the benefits if using the mechanics of the distributor still. A controller box would be an awesome feature for those who need to stick with an OBD2 capable ecu.

aem and k series coils seems to be a great setup

The one thing about an electronic device to convert mechanical distributor to COP is that it has to be tailored to the specific coil specs. That's why in a standalone that supports smart coils you have to setup dwell, min, max, rising edge or falling edge etc etc.. or you can burn up coils. We were trying the same thing last year and gave up on the project. Easier to use a S13 ecu or just go standalone. Since the technology exists why re-invent the wheel (was our thoughts after playing with it)


From the EMS software:

Note that the options "Dwell Max" and "Dwell Min" will override the Dwell Factor, Dwell vs Batt Volts, and Dwell vs RPM settings.
It is recommended to monitor the Dwell Time channel, which shows the actual dwell time of the pulse being sent from the EMS to the ignition coil (or ignitor, if equipped).
