Dynatek 21010043 Electronic control unit

Manufacturer's ref: DD2000-HD1EP — Dyna programmable digital ignition module for Harley. Designed for vintage and touring enthusiasts who want precise and adaptable ignition management, this microprocessor-controlled module replaces the original electronic advance control to optimise engine response on the road or in roadster use.

• PC programmable: allows you to set full and partial advance curves, rev limits, and other parameters to adjust the ignition to engine modifications.
• Four built-in advance curves covering configurations from stock setups to heavily modified engines.
• Rev limiter: four independent ranges from 6,000 to 7,500 rpm to protect the engine.
• Single-fire or dual-fire mode: works with a single coil for both cylinders or with two coils, one per cylinder.
• Connections: supplied with a 7-pin connector and diagnostic LED for easy timing and troubleshooting.
• Manufactured in: United States.

Important: not compatible with fuel-injected models. HDE systems are not compatible with Dyna "S" systems — use only HD1/HD2 systems. For any electronic advance ignition (Dyna 2000-HD1 or original Harley), prefer carbon fibre suppression ignition cables; copper cables may cause interference. The original Harley-Davidson cable remains suitable.

Ideal for vintage Softail and Bad Boy models (e.g. FXSTSB, FXSTS, FXSTC from 1995), this module offers the necessary flexibility to fine-tune the ignition and achieve the performance and consistency suited to your setup.
