MSD Ignition 2-Step Module Selector Allows you to choose two or three different rpm limits that can be activated at different times. With this ability, the possibilities are endless. For example, by connecting one wire to the line-lock circuit, one module will be activated during the burnout. This helps keep tire temperatures consistent. When the line-lock button is released, the limit turns off. When you're on the starting line, you can activate the second limit through the clutch or trans switch. This provides a steady and consistent rpm for firm holeshots every time. When no modules are selected, the remaining high limit is active to protect the engine in the event of driveline failure. The Two Step works the same, but only with two different limits. To be used with MSD 6AL, 7 Series, MSD8728/8738 Soft Touch rev limiters or timing computers. No rpm or retard modules are supplied.
