I originally want to use Kettering style ignition, because I understand points. I'll go to 7 or 8 pin HEI later.
I believe I should set "Ignition Input Capture" to "Rising edge" as that would be the rising signal when the points open with the Pull-up resistor attached. But there is an optical isolator just before the CPU, I believe that might invert the signal.
1) For the Ignition Input Trigger should I use "Rising Edge" or "Falling Edge"?
2) Cranking trigger; "Calculated", "Trigger Rise" or "Trigger Return"?
3) "Standard coil Charge" should be right since that's what I'm using.
4) "Spark output" should be "Going High" for a normal coil.

Thanks for the help.

Use falling edge and Trigger Rise.

Thanks Matt. I'll give it a shot.
