MSD ASY10178 RPM Module Chip Rev Limiter Plug-In - 7000

The MSD ASY10178 is a 7000 RPM plug-in module chip designed to precisely set the rev limit on compatible MSD ignition systems. Also commonly referred to as an RPM pill or RPM chip, this small but critical component gives performance enthusiasts and racers a simple, no-laptop method of dialing in engine protection and launch control.

• Fixed 7000 RPM rev limit — sets a hard rev ceiling to protect against over-rev damage from missed shifts or driveline failure
• Plug-in installation — inserts directly into the RPM module socket on compatible MSD ignition boxes and Soft Touch Rev Controls
• No programming required — simple swap-in design requires no tuning software or digital interfaces
• CARB compliant — legal for sale and use on emissions-controlled vehicles in all 50 states with applicable CARB Executive Order (EO) number
• Sold individually — single 7000 RPM module; also available in 200 RPM increment kit sets for fine-tuning

Compatible with MSD Soft Touch Rev Controls, MSD ignition boxes with an integrated rev limiter, and other MSD accessories that use plug-in RPM modules. Ideal for drag racing, road racing, or street performance applications where a precise, repeatable rev limit is essential for engine protection and consistent performance.
