Ignition setting - rising vs falling
 

I have a stock ignition system in my FD with an igntion (mallory hyfire, digital CDI) amplifier installed after my stock ignitor to my leading coils. Should my ignition be set to rising or falling? I assumed since I am still using the stock ignitor that the ignition should be set to falling, but I am not sure so I thought I would see what everyone else is doing? My ECU is an E6K.

Leave it the same if the factory ignitor is still in place.
When using MSD to fire the coils directly then set it to rising, constant duty with a 50% duty cycle and always double check ignition timing.

Factory Igniters = Falling, almost 100% of the time. CDI's usually are set like crispeed indicated.

Thanks!
