Daytona Twin Tec Twin-Tuner2 For Harley Davidson

Harley® owners looking for improved motorcycle performance can easily add horsepower and improve throttle response with a simple and low cost modification. The Daytona Twin Tec Twin-Tuner2 Fuel Injection and Ignition Controller allows you to easily adjust your fuel injection to match the requirements of your performance parts including camshafts, free flowing exhausts, and low restriction air filters. It has all the features of the original Twin Tuner and includes ignition timing control capability. The simple plug-in installation and set up takes only minutes and requires no splicing or bulky interconnections. The unit is completely encapsulated and impervious to moisture. With a low 1/2″ profile, occupying only a fraction of the space required by competitive products, you won’t have a problem finding a place to mount the unit.

The user interface consists of up/down pushbuttons and bright daylight readable LED display to select and change the fuel trim and spark retard in the RPM and throttle position ranges required by most applications. The Twin-Tuner2 also has an advanced mode, where you can use the optional USB Interface and PC Link Tuner software to make precise fuel and spark retard adjustments as well as making independent adjustments to the front and rear cylinders. If you have created Dynojet Power Commander Files for your applications, you can enter the same values into our tables because the PC Link Tuner software uses the same RPM rows and throttle position columns.

The Twin-Tuner2 works in combination with the Twin Scan II+ tuning aid, giving you precise tuning without the need for a dyno. Simply install the Twin Scan II+ and ride the bike. You can then download the air/fuel ratio corrections calculated by the Twin Scan II+ into the PC Link Tuner software.

*The Twin-Tuner2 is not legal for sale or use on pollution controlled vehicles.
