MSD ASY17893 6500 RPM Module Chip Rev Limiter for MSD Ignition Boxes

The MSD ASY17893 is a plug-in 6500 RPM module chip designed to set a precise rev limit on compatible MSD ignition systems. This single plug-in chip installs directly into the RPM module socket found on MSD Soft Touch Rev Controls, MSD ignition boxes with an integrated rev limiter, and other MSD accessories that accept plug-in RPM modules.

Swapping RPM modules is one of the easiest ways to dial in your rev limit — simply pull the existing module and plug in the desired chip for an instant RPM limit change with no tools or wiring required. The 6500 RPM setting makes this module a popular choice for IMCA-class racing applications where strict rev limit rules apply.
