DYNATEK DD2000-HD2EP Ignition Module — Replaces the original unit with a programmable digital ignition box designed for recent Harleys. Designed for riders who want to refine engine response, this microprocessor-controlled module allows adjustment of the advance curve and rev limit without modifying the main harness: plug-in installation at the original location.

• PC programming to define full and partial throttle advance curves.
• Four built-in advance curves, suitable from stock engines to more advanced setups.
• Four independent rev limiters, adjustable from 6,000 to 7,500 rpm.
• Separate tachometer output for precise tachometer operation, even in limit or single-fire mode.
• LED diagnostic indicator at the back of the module for easy troubleshooting and static timing.
• Direct connection to the original 7-pin harness; mounts in the original location. Made in the USA.

Usage Information and Compatibility: Not compatible with fuel-injected models or Dyna "S" systems — to be used only with HD1/HD2 systems and dual-fire ignitions. Important: to reduce radio interference, use carbon fibre suppression ignition cables; copper cables may cause malfunctions (the original Harley-Davidson cable remains compatible).

This module is aimed at Vintage/Classic, Touring, and Roadster enthusiasts seeking more precise and adjustable ignition management, without compromising on reliability and ease of installation.
