Yes run the E-core coil. Produces much more magnetism with the full 12 volt feed and no ballast resistor. In turn produces much hotter spark.

Here is a good video on ohms resistance numbers on different coils.

The e-core benefits are definitely there, but my understanding was that the controller (ECU, MSD box, whatever) had to have the necessary dwell control capability.

Fitech sells their own CDI ignition box and e-core coil pairing. So it had me scratching my head why that product exists if the regular ECU could run an e-core coil without issue.
