Daytona Twin Tec Model 1005: Precision Programmable Ignition for Classic Harleys

The Daytona Twin Tec Model 1005 Fully Programmable Ignition is the premier performance choice for Harley-Davidson enthusiasts looking to modernize their 1970–1999 machines. This high-tech, digital module fits entirely inside the engine’s nose cone, providing a sleek, hidden installation that eliminates the need for bulky external ignition boxes. Designed to survive the heat and vibration of high-performance V-Twins, the Model 1005 brings modern digital precision to classic Shovelhead and Evolution engines.

Ultimate Tunability: 16 Advance Curves & PC Programming

The Model 1005 is built for versatility. Out of the box, it features 16 built-in advance curves that can be easily selected using on-board rotary switches to suit a wide variety of engine states and fuel grades. For the advanced tuner, this unit is fully PC-programmable (requires optional interface cable), allowing you to create custom 2D timing maps, adjust VOES (Vacuum Operated Electric Switch) parameters, and fine-tune your engine’s performance for maximum wide-open-throttle horsepower.

Single-Fire or Dual-Fire Capability

One of the most significant upgrades you can make to a classic V-Twin is moving to a Single-Fire ignition. The Model 1005 allows you to choose between single-fire (firing each cylinder independently) or dual-fire (stock configuration). Single-fire operation eliminates the “wasted spark” on the exhaust stroke, which results in reduced engine vibration, lower operating temperatures, and a significantly more stable idle.

Integrated Rev Limiter and Data Logging

Protect your investment with a highly accurate digital rev limiter, adjustable in 100-RPM increments via the PC interface or through selectable switch positions. Beyond just timing, this module acts as a flight recorder for your motorcycle; it features internal data logging that tracks total engine hours, number of starts, time spent at wide-open throttle, and maximum RPM reached, providing invaluable diagnostic data for builders and tuners.

Intelligent Starting and Durability

Large-displacement engines are prone to “starter kick-back,” which can damage expensive primary components. The Daytona Twin Tec module features an intelligent starting algorithm that manages spark timing during the first two revolutions to ensure smooth, effortless starting. The unit is housed in a rugged billet aluminum casing and features fully encapsulated (potted) electronics to protect against moisture, oil, and the mechanical shock of hard-tail frames.

Fitment and Compatibility (1970–1999)

The Model 1005 is designed for “nose cone” ignition applications, including:

Harley Big Twin (1970–1999): Fits Shovelhead and Evolution (Evo) engines (Softail, Dyna, and Touring).
Harley Sportster (1971–2003): Fits Ironhead and Evolution Sportster models.
Custom V-Twins: Direct replacement for S&S, RevTech, and Ultima engines using classic ignition configurations.

Daytona Twin Tec Fully Programmable Ignition For Harley

This fully programmable ignition features two advance curve families that are adjustable to accommodate stock and modified engines. Selectable multi-spark mode for quick starting and smooth cruising.
