2-Step Launch Control - GM LS Engines

The 2-Step Launch Control for GM LS Engines (MSD 8733) is a specialized ignition module designed to enhance traction during launches in drag racing and high-performance applications. This controller allows for a controlled launch RPM, helping to prevent wheel spin and improve consistency during acceleration. It is ideal for LS-powered vehicles where traction is critical for achieving lower elapsed times (ET).

The module operates by managing engine RPM during the launch phase, allowing for a smoother power delivery that keeps the tires from spinning. Once the vehicle gains sufficient traction, the system automatically adjusts to the user-programmed ignition timing curve for optimal performance. This design reduces shock load on the drivetrain and enhances overall consistency in racing scenarios.

Bracket racers, street/strip enthusiasts, and dedicated drag competitors running Gen III and Gen IV LS engines will find this module particularly beneficial for achieving repeatable launches. Its compact design integrates easily into existing MSD ignition harnesses, making installation straightforward for those with intermediate ignition knowledge.
