Model 1005K fits all HD® engines with nose cone ignitions and is adaptable to most older engines when used in conjunction with an aftermarket distributor. The internal ignition unit is triggered from the OE timing rotor at the end of the camshaft. It eliminates the bulky OEM ignition wire harness and external module - the resulting clean appearance is especially desirable on custom motorcycles.

The Model 1005K is constructed with a low profile machined billet aluminum housing. Four rotary switches are used to set the operating modes (such as single or dual fire, advance curve family, and multi-spark), adjust the timing advance, and select the RPM limit. Two diagnostic LEDs indicate status and the state of the vacuum switch (VOES). The status LED is also used for static timing, as it will flash when the engine reaches top dead center (TDC).

The unit offers two advance curve families - street and race. You can also adjust the slope of the selected advance curve. The user can optimize the timing advance for a wide range of applications from stock to highly modified engines. For details, including advance curves, you can download the installation instructions from the Daytona Twin-Tec link on our webpage.

Switch selectable single or dual fire mode allows you to initially install the unit and run it in dual fire mode with your stock coil. You can then easily upgrade to single fire by adding an appropriate coil. If you have a tach, it will continue to operate properly (some competitive systems require that you purchase a tach adapter).

An optional PC link cable and Windows compatible software allow the use of a laptop PC to program a custom advance curve for precise dyno tuning. The PC link also provides access to additional features such as rear cylinder timing offset. You can download the software from our website and use it in demo mode without an ignition attached. The PC link cable is sold separately. Refer to PC link product bulletin for details.
