I'm running a Jacobs FC1000 right now, which is basically the same thing as a MSD 6a. I want to run a MSD 2-step so I can have a controlled launch every time. I have searched all over on how to put in a 2-step with our not so basic ignition system, and just about every thread or piece of information says something different. Very contradictory and confusing when trying to learn...

So to make it easier on myself, I'm think of just swapping the FC1000 for a MSD 6al. Not the new 6al-2, but the older 6al. These come with a built in slot for a rev-limiter "pill". But i think instead of running a pill there, I can just plug an MSD 2-step in and be good to go.

But the main problem I think is that I will have the 6al wired to my leading coil pack only. So will the 2-step work, or give me the same effect, if the trailing coils arnt touched at all by this?

if you are running waste spark witch it sounds like,you will need 3 6al's,if you don't you will have zero control over the trail ignition,the 2 step boxes plug into the 6al's,then you can wire in a clutch switch to activate them,so when you are at the line with the clutch in,the engine will only rev to what ever pill you put in the low side,then when you launch the 2 step will switch to the high side.

The links posted above, and other things i have found are done with one 6al. They just use a relay to shut off the trailing coils completely when the 2-step activates. Which is what i am going to do.
