The 2-Step Launch Control is a low rpm limiter only. The factory speed limiter will not be affected.

This MSD 2-Step Launch Control is designed for Ford Modular 5.0L engines with Coil-on-Plug ignitions. The

2-Step Control switches to a lower rpm limit that will assist in consistent launches and 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 rpm increments. An LED will illuminate when the launch rev limit is active.

Note: It is recommended to have the Service Manual for your vehicle. If you cannot identify an

activation wire, a microswitch or relay may be required.

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.

IMPORTANT: Due to wiring variations on different models, MSD cannot identify specific wiring on

the clutch switches. Consult your Service Manual for wiring schematics.

MOUNTING

The 2-Step Control can be mounted in any

position but keep in mind to mount it so the
