Can someone shed some light on this situation, the first picture I'm posting is my old Dynatek settings for my stock coil pack, and nothing has changed but the new Dynatek has a couple unfamiliar settings on it.

I need some information on the which setting should be used for the falling and rising edge option with a standard coil pack and also which setting for the cam or crank trigger. This a 6 bolt swap car, with a black top CAS.

The falling/rising edge correlates to the std coil/coil w driver setting on the previous one. As you can see on the previous one, those also had arrows showing a falling edge, and a rising edge. Set that to rising edge.

The cam/crank setting is whether it fires every 360 degrees (wasted spark), or once every 720 degrees (sequential). 360 degrees would be crank, 720 degrees would be cam. This primarily affects the rev limit RPM calculation, and the built in timing retard calcs.

Set it to crank to work with the OEM setup.
 
So I have a question about the ARC-2. I just installed mine on my 93 and as I understand, I need to set it to coil w driver and remove the power transistor. (little black box on the coil) I have the stock coils on my 1g.

Then set the other dip switch to single spark, I don't care about emissions and am not setting timing or anything.

Just want to confirm this is the right way for me to have it set. Thanks!

Setting it to restrike is better for cruise/idle, and it won't affect the performance of it at WOT. The biggest reason to set it to single strike is to set timing.

If you set it to rising edge (what was the STD COIL setting), then you can leave your power transistor in, and use the plug in harness that will get your tach functioning right etc. If you HAVE to cut into your harness to delete the stock power transistor, then yes, use the falling edge.
