MSD 2-Step Rev Control unit, developed by MSD's engineers in light of the new rotary dial adjustment design on the superb new Digital 6AL Ignition controller. The 2-Step Rev Control unit can be added to your ignition system to enable the ability to switch to a low rpm limit to use on the starting line.
There are two easy to read rotary dials that let you set the launch rpm in 100 rpm increments and there is an activation wire that connects to the transbrake, a clutch switch or to the line-lock to activate the low rpm limit. When that switch is released, the low rpm limit is turned off and the car launches hard!
The 2-Step is also digitally controlled and connects to the Digital 6AL's gray tachometer output wire. For use with Digital 6AL PN 6425 or 64253 only.

- Easy setup with two rotary dial switches
