Launch Control Module Selector

The MSD Launch Control Module Selector (MSD 8735) is a 3-step programmable rev limiter and launch control system designed for serious drag racing and high-performance engine tuning. This selector module works with MSD 6-Series and 7-Series ignition systems to enable precise engine speed management across three independent stages, allowing drivers to hold a consistent RPM at launch for maximum traction control and minimal wheel spin off the line.

The MSD 8735 offers adjustable rev-limit settings from 1,000 to 10,900 RPM in 100 RPM increments, giving tuners granular control over engine performance across multiple launch scenarios and track conditions. The three independent stages enable progressive acceleration management—holding engine RPM steady during the initial launch phase, then allowing higher RPM during mid-range acceleration, and finally permitting full RPM at top-end operation. This staged approach maximizes grip off the line while preserving engine safety margins and mechanical durability through controlled power delivery.

Purpose-built for bracket racers, heads-up competitors, and high-performance street-strip vehicles, the Launch Control Module Selector integrates seamlessly with MSD's proven ignition platform. The compact form factor (4.4 x 3.3 x 4.8 inches, 0.65 lbs) fits easily within engine bay installations. This selector is an essential tuning tool for drivers seeking consistent launch RPM management and improved elapsed time through controlled engine acceleration strategies.
