Daytona Twin Tec Fully Programmable Ignition For Harley 1999-2003
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.
