Also Fit most Evolution and Shovelhead engines (carbureted models only, not for fuel-injected bikes). High-Output Single-Fire Coil: High-output single fire coil designed to deliver a strong, consistent spark for reliable ignition performance when properly installed and tuned. Programmable Ignition Functions: Includes multiple adjustable ignition curves for part-throttle and wide-open-throttle use, rear-cylinder timing adjustments available when used with the programming kit.

Built-In Safeguards: Intelligent circuitry protects against short-circuits, over-voltage, and over-current conditions to prevent electrical damage. A durable solid-state design ensures long-term reliability - just use proper wiring (correct coil polarity and no solid-core plug wires) for safe operation. Professional installation is strongly recommended. Data & Usage Information: Supports recording of engine hours, maximum RPM, time at wide-open throttle and number of starts when used with the programming kit, helping you monitor engine use and plan maintenance.

Electronic module with no moving points. Designed for stable, long-term use when correctly installed.
