The Twin Tuner allows you to easily adjust your fuel injection to match the requirements of performance parts including camshafts, free flowing exhausts, and low restriction air filters. You can add up to +30% or subtract down to -20% fuel.

You can use the mode and up/down pushbutton switches to make fuel trim adjustments in the RPM and throttle position ranges required by most applications. The fuel trim value is displayed on a bright daylight readable LED display.

The Twin Tuner also has an advanced mode, where you can use the optional USB Interface and PC Link Tuner software to make precise fuel adjustments. The PC Link Tuner software uses the same RPM rows and throttle position columns as the Dynojet Power Commander. If you have created Dynojet Power Commander files for your applications, you can enter the same values into our tables. You can make independent adjustments to the front and rear cylinders.

The Twin Tuner works great in combination with the Daytona Sensors Twin Scan II+ tuning aid. You don?t need a dyno for precise tuning. All you have to do is install the Twin Scan II+ and ride the bike around some. You can then copy the air/fuel ratio corrections calculated by the Twin Scan II+ into the PC Link Tuner software.

Buell? users please note that the standard Twin Tuner works with the 2008-2009 models with the new DDFI module that has two 34 pin Delphi? connectors including the new 1125R model with Rotax engine. P/N TWIN-TUNER-BUELL is for 2003-2007 models with the earlier DDFI module that has two 12 pin Deutsch connectors.

The new Twin Tuner EX version is 50 states street legal (ARB E.O. D-641). Fuel adjustments with the Twin Tuner EX are only allowed above 60% throttle position or 5000 RPM.
