Thunder Heart Performance Stand Alone Ignition For Harley 1999-2007
Thunder Heart Performance EA5012: The Custom Builder’s Stand-Alone Ignition
The Thunder Heart Performance Stand-Alone Ignition System is engineered for the serious custom builder and performance enthusiast. Specifically designed for Harley-Davidson Twin Cam engines from 1999 to 2007 (and later custom applications), this system is the perfect solution for putting a modern Twin Cam motor into a custom frame or converting an EFI bike to a carburetor. By eliminating the bulky factory wiring harness and ECM, the EA5012 provides a streamlined, professional, and high-performance electrical foundation for your V-Twin.
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.
Installation and Kit Contents
The EA5012 is a comprehensive kit designed to get your engine running with just a few simple connections (Power, Ground, and Crank Sensor). The kit includes:
- Integrated Module & Coil: Housed in a polished billet aluminum casing.
- Spark Plug Wires: High-quality, custom-length wires for a perfect fit.
- Programming Hardware: Smart Link software and PC interface cable.
- Hardware: Electrical connectors, ring terminals, and detailed instructions.
- Mounting: Designed for standard motor mount spacing (1/4-20 bolts).
