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.
The Daytona Twin Tec Model 1005 is more than an ignition; it is a complete engine management system for your V-Twin. With its static timing LED for easy “no-light” setup and its proven track record on both the street and the drag strip, it is the ultimate upgrade for riders who demand the absolute best in reliability and performance.

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.
Features:

An upgrade from the non-adjustable stock OEM unit
Features advanced electronics set into a billet aluminum housing
Four rotary switches are used to set the operating modes (such as single or dual fire), adjust the timing advance, and select the RPM limit
Two diagnostic LEDs indicate the status and the state of the vacuum switch (VOES)
The status LED is also used to indicate top dead center (TDC) for easy timing set-up
A special feature allows use of the tachometer wire for a link to a laptop PC
While the customer does not require the PC link for any normal set-up or operation, it can be used to access additional features for precise dyno tuning (such as programming a custom advance curve and setting rear cylinder timing offset)
Windows compatible software is freely available for download at the company website
PC link cable sold separately
Made in USA

Daytona Twin Tec Model 1005: Advanced Digital Ignition for Carbureted Twin Cams

The Daytona Twin Tec Fully Programmable Ignition is the premier tuning tool for Harley-Davidson Twin Cam 88 engines equipped with a carburetor. Designed as a direct plug-and-play replacement for the factory module, the Model 1005 offers a level of precision and adjustability that the stock unit cannot match. Whether you are looking to eliminate engine “pinging” on a stock bike or fine-tune a custom big-bore build, this module provides the digital “brain” required for peak V-Twin performance.

Total Tuning Flexibility: 16 Advance Curves

The Daytona Twin Tec features 16 built-in advance curves that can be easily toggled using on-board rotary switches. These curves are specifically mapped to accommodate various engine displacements and fuel octanes. For the advanced tuner, this module is fully PC-programmable (requires optional interface cable), allowing you to create custom timing maps, adjust VOES parameters, and log engine data for professional-grade tuning.

Precision Rev Limiter & Safety Controls

Protect your engine with an integrated, high-accuracy digital rev limiter. Adjustable in 100 RPM increments (via PC) or through selectable switch positions, the limiter ensures you stay within the safe operating range of your valvetrain. Unlike factory limiters that can be “lazy,” the Daytona Twin Tec provides a crisp, immediate cut-off to prevent over-revving during aggressive shifts or missed gears.

Superior Starting & Smooth Operation

Large-displacement Twin Cams can be notoriously difficult to start, often suffering from “starter kick-back.” This module features a programmable cranking delay and an intelligent starting algorithm that manages spark timing during the first few revolutions. This results in reliable, effortless starts and significantly less wear on your starter motor and ring gear. Once running, the high-energy spark ensures a smooth idle and crisp throttle response across the entire powerband.

Direct Plug-and-Play Installation

Engineered for a clean, factory-style fit, the Model 1005 utilizes the standard Harley-Davidson 12-pin connector. It is a true bolt-on upgrade that works with all factory sensors, including the MAP and Crank Position Sensor (CPS). The module is housed in a rugged, heat-resistant casing that fits perfectly in the original equipment location, making it a “stealth” performance upgrade that maintains your bike’s clean aesthetic.

Fitment and Compatibility (1999–2003)

This module is designed specifically for carbureted Twin Cam 88 models:

  • Harley Softail: 2000–2003 Carbureted models.
  • Harley Dyna: 1999–2003 Carbureted models.
  • Harley Touring: 1999–2003 Carbureted models (Road King, Electra Glide, etc.).
  • Note: Not compatible with Fuel Injected (EFI) models or 2004-later models using the smaller 18-pin connector.
Experience the power of digital precision with the Daytona Twin Tec Model 1005 Ignition. Built in the USA for the most demanding riders, this module is the most effective way to optimize the timing of your carbureted Twin Cam. From improved fuel economy to maximum wide-open-throttle horsepower, trust Daytona Twin Tec to power your ride.
