The MSD Powersports Launch Master is a universal low rpm limiter. The Launch Master will provide
consistent launches and quicker 60-foot times. RPM adjustments are made via two rotary switches
located on the harness side of the unit. The adjustment range is from 1,800 to 9,900 rpm, in 100 and
1000 rpm increments. An LED will illuminate when the launch rev limit is active.
Note: It is recommended to have the service manual for your motorcycle.
MOUNTING
The Launch Master can be mounted in any position but keep in mind to mount it so the rotary dials
are accessible for adjustments. A section of Velcro is supplied for mounting. Double sided tape or
tie wraps are also recommended depending on the final mounting area. Before mounting the unit,
confirm that the wiring harnesses reach their connections.
