MSD ASY11555 8800 RPM Module Chip Plug-In Rev Limiter

The MSD ASY11555 is a single plug-in 8800 RPM module chip designed to precisely set the rev-limit on compatible MSD ignition systems. This small but critical component gives racers and performance enthusiasts a straightforward, no-tuning-required method to protect their engine and control peak RPM.

How It Works:

The RPM module chip plugs directly into the dedicated RPM module socket found on MSD Soft Touch Rev Controls, MSD ignition boxes with an integrated rev limiter, and other compatible MSD accessories. Once installed, the chip signals the ignition system to cut spark at exactly 8800 RPM, providing consistent and repeatable over-rev protection without the need for laptop programming or digital interfaces.

Key Features:

• Sets rev-limit at a precise 8800 RPM
• Direct plug-in installation — no wiring or programming required
• Compatible with MSD Soft Touch Rev Controls, 6AL, 7AL, and other MSD ignition boxes with integrated rev limiter sockets
• Sold individually (single chip)
• CARB-compliant — legal for sale and use on emissions-controlled vehicles in all 50 states (CARB E.O. D-40-29)
• Lightweight and compact design

The MSD ASY11555 is an ideal solution for high-performance builds where precise RPM control is critical, whether you're dialing in a race engine, protecting a fresh build, or fine-tuning a launch or shift point. Swap chips quickly at the track to adapt your rev limit without any tools.
