Pantera EFI is on a distinguished road
Default Secondary Resistance Coil/Plug

Hi Peter, as you know, ARC Duration (your correct art of Spark Duration Measurement @ 380us) states a GOOD quality of current flow, there is a requirement of the Spark Instant/Length with respect to rotor position.

Your current design has NO resistance between the coil/plug.

The addition of a resistor there WILL increase Arc Duration, I good thing for CDI style ignition.

Would it be possible to add a small resistor inline ?

I truly would like you to achieve best performance from the IGN-1CD (early) coil.
