MSD 2-Step RPM Controller (FORD 4.6L)

This 2-Step connects right to your late model Ford to produce consistent launches and quicker 60-foot times by setting an rpm limit to stage with. When activated, the rpm will be held at a steady rpm and once the green light comes on, release the clutch and take off - but be sure to hold on! The rpm is adjusted with two built-in rotary dials ranging from 1,800-9,900 rpm in 100 rpm increments. A handy LED shows when the launch rev limit is active.

NOTE: For use on Coil-on-Plug systems only.
