All-In-One Compact Design

Unlike traditional setups that require a separate ignition module, coil, and extensive wiring, the Thunder Heart system consolidates everything into a single billet aluminum housing. This weatherproof and vibration-resistant unit mounts directly between the cylinders, creating an incredibly clean look. The integrated high-output single-fire coil is tuned to work perfectly with the internal digital processor, ensuring a consistent, powerful spark that improves combustion and throttle response.

Fully Programmable Digital Precision

The EA5012 offers two levels of tuning. For a quick setup, an on-board rotary switch allows you to select from 16 pre-programmed advance curves. For those seeking maximum performance, the kit includes Smart Link software and a communication cable. This allows you to connect a laptop and fully customize the front and rear cylinder timing, set specific RPM limits, and access real-time diagnostic data—making it the ideal choice for high-compression or large-displacement builds.

Optimized Starting and Reliability

By utilizing the factory Crank Position Sensor (CPS), the Thunder Heart system achieves superior timing accuracy compared to cam-driven units. The intelligent software manages the initial cranking revolutions to prevent engine kick-back, which protects your starter motor and ring gear. Its “stand-alone” nature means the ignition operates independently of other bike electronics, making it a favorite for “bobber” or “chopper” projects where minimal wiring is required.
