The DSM's are falling edge and use an ignitor. The evo's are rising edge and have the ignitor built into the coil. You'll also notice the DSM coils are physically MUCH larger than the evo units and as an inductive system goes they are superior to the evo's.

Can you explain the significance of the rising edge/falling edge? Why I ask is I am running an Evo8 ECU in a DSM type setup. It seems to work fine, but this has me concerned.
