0-11 Degree Retard Module Selector

The 0-11 Degree Retard Module Selector from MSD Ignition is a precision timing control module designed for tuners and performance enthusiasts who need independent adjustment of ignition timing retard. This selector allows fine-tuned management of spark advance curves in high-performance and racing applications where optimized combustion timing directly impacts engine efficiency, fuel economy, and power output. Whether you're dialing in a street engine or maximizing track performance, this module delivers the granular control required for precise ignition system tuning.

This timing selector operates across a 0-11 degree adjustment range in 1-degree increments, enabling precise retard calibration without coarse jumps in timing values. The modular design integrates seamlessly with MSD Ignition timing controllers, allowing users to dial in optimal spark timing for specific fuel octane ratings, engine loads, and boost conditions. The compact form factor (6.05 x 2.25 x 7.95 inches) and lightweight construction (0.35 lbs) make installation straightforward in tight engine compartments. One-degree step increments ensure repeatability and eliminate guesswork when establishing the ideal ignition curve for your application.

Serious drag racers, street rod builders, and performance engine tuners rely on MSD timing modules to extract maximum power while maintaining engine reliability. This selector is ideal for carbureted and fuel-injected engines where traditional fixed timing falls short. Users typically employ this module as part of a complete MSD Ignition system, pairing it with compatible controllers to achieve dynamic timing management across the entire RPM band. Installation requires integration with your existing MSD timing control harness—consult your specific system documentation for proper wiring and calibration procedures.
