Getting a consistent launch out of a late-model LS car means holding the engine at a repeatable rpm while you stage. This 2-Step launch control module wires into a Gen III or Gen IV GM LS ignition system and adds a second, lower rev limit that stays active while the activation switch is closed, so you can hold the throttle down without over-revving and leave on the same rpm every pass.

MSD 8733 2-Step Launch Control Module Features:

• Adds a second, lower rpm limit used for staging and launching.
• Connects to late-model GM LS engines using factory style connectors for a splice-free installation.
• Compatible with both 24x and 58x crank trigger wheels.
• Works on cars with manual or automatic transmissions.
• Helps produce quicker, more consistent 60-foot times.
