Haltech trigger setup

trigger setup
What is the difference between the "trigger signal edge" in the trigger setup tab and the "ignition spark edge" in the ignition setup tab? I am pretty sure the trigger edge should be falling but what should the ignition edge be?
Thanks

Stock FC and FD use falling on the ignition input trigger edge.
Most dumb ignitors (including the stock ignitors on FC and FD) need a falling ignition output edge.
The only reason to change this to rising is if you're using CDI boxes or some kinda weird, aftermarket smart ignitor?

Thanks for the info Ted. I read the instructions for both the DIS4 and the digital-6 and neither made mention of the type of trigger required to function properly. The problem i am having is that after i zero the timing and while it is still locked as the RPM varies so does the timing. I know if the trigger edge is set wrong the timing will do exactly that but i did not know if the spark edge had the same effect. I wanted to make sure before i just started changing setings. And ALL the features on both MSDs are disabled.
Thanks again

With the MSD 6-Series, you will want to run a RISING spark edge(ignition) on CONSTANT DUTY, and a switching after point at/around 50%. You can leave a spark break time of 600ms.
Those Ignition systems operate differently from the stock Ignitors on FC/FD's...
