Show original supplier description
The Daytona Twin Tec 2101-0241 is an internal ignition system engineered for Harley Davidson motorcycles, specifically fitting '99-'03 Twin Cam carbureted models with two 12-pin connectors. This module provides enhanced ignition control with two adjustable advance curve families, suitable for both stock and modified engines. Its selectable multi-spark mode ensures quick starting and smooth cruising. Four rotary switches allow for precise adjustments to timing, single/dual ignition mode, and rpm limit in 100-rpm steps. The ignition outputs are protected against short circuits for added durability. For optimal performance, this module requires OEM coils with less than 1 ohm primary resistance and low-resistance spiral-core or carbon-core suppression-type plug wires. A USB interface (Part #2101-0075) is necessary for programming.
