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
rotary dials are accessible for adjustments
(Figure 1). Hardware is supplied for mounting.
Before mounting the unit, confirm that the
wiring harnesses reach their connections.
