396 Stocker Motor won't RPM

[Lew Silverman]

I was hoping to find out what add-on module Bobby was using on his 6AL-2. I've been looking for a way to add a third "step" limiter to my system, but from what I've been able to research the -2 has no compatible add-on module available from MSD, just the two built-in settings. I may have to upgrade to another box to take advantage of that third step.
