8100-8900 RPM Odd Series Module Kit

The 8100-8900 RPM Odd Series Module Kit from MSD Ignition is a precision ignition control module designed for high-performance engine tuning and competition applications. This module is ideal for engine builders and tuners who require precise control over spark delivery across narrow RPM bands, particularly in high-revving environments.

Operating within the 8100–8900 RPM range with 200 RPM increments, this module allows technicians to program ignition curves with precision tuning. Its compact form factor—measuring 6 × 1 × 7.8 inches and weighing only 0.13 lbs—ensures easy integration into existing MSD Ignition harnesses without extensive rewiring.

Engine builders working with naturally aspirated, supercharged, or turbocharged platforms will find this module particularly beneficial for RPM-specific tuning, making it suitable for applications in bracket racing and street performance.
