6000 RPM Module

The MSD Ignition 6000 RPM Module (ASY11216) is a precision engine control chip designed for ignition timing management in high-performance applications. This compact module limits engine RPM to 6000 revolutions per minute, providing critical over-rev protection for engines operating at sustained high speeds or in boost conditions where uncontrolled RPM escalation could cause catastrophic damage.

MSD Ignition's RPM limiter modules are engineered to prevent engine damage by cutting ignition spark when peak RPM is reached, automatically resuming ignition when RPM drops slightly below the threshold. The 6000 RPM setting suits applications requiring strict RPM control—including street and strip vehicles, marine engines, and forced-induction builds where engine block integrity depends on staying within safe operational limits. The module's compact form factor (2.1 x 0.65 x 3.05 inches) and negligible weight (0.01 lbs) integrate easily into existing ignition harnesses without adding bulk or complexity to engine compartment routing.

This module is essential for builders and enthusiasts tuning carbureted or fuel-injected engines where factory rev limiters are absent or insufficient. Serious drag racers, road course competitors, and performance marine technicians rely on MSD RPM modules to safeguard high-dollar builds during acceleration runs and full-throttle operation. The 6000 RPM ceiling is ideal for mid-range displacement engines or heavily modified stock blocks where higher limits would risk structural failure.

MSD's reputation in the ignition control market is built on decades of reliability in professional racing and aftermarket performance. The 6000 RPM Module represents a proven solution for protecting expensive engine investments and maintaining consistent performance across repeated high-load cycles. Whether upgrading a classic engine, protecting a supercharged build, or establishing precise RPM control in a custom application, this module delivers transparent, set-it-and-forget-it protection.
