Note: The 2-Step Launch Control is a low-rpm limiter that will not provide nor modify any overrev
protection. The stock high rpm rev limiter will still be active.
The MSD 2-Step Launch Control is designed for Ford Modular Enhgines with Coil-on-Plug ignitions. The
2-Step Control will provide consistent launches and quick 60-foot times. RPM adjustments are made via
two rotary switches located on the harness side of the unit. The adjustment range is from 1,000 - 10,900
rpm, in 100 and 1000 rpm increments, an LED will illujminate when the launch rev limit is active.
Note: It is recommended to have the service manual for your vehicle.
Note: The engine rpm must drop more than one third of the set launch limit in order to activate. For
example, if the launch limit is set at 3,000 rpm, the engine speed must drop below 2,000 rpm
in order for the launch limit to become active (one third of 3,000 rpm is a 1,000 rpm drop).
Caution: Keeping the engine on a lower rpm limit may cause the Check Engine light to come on
and could potentially damage the catalytic converter.
MOUNTING
The 2-Step Control can be mounted in any position but keep in mind to mount it so the rotary dials
are accessible for adjustments. Hardware is supplied for mounting. Before mounting the unit, confirm
that the wiring harnesses reach their connections.
