Twin Turner EX Fuel Injection Controller

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. Fuel adjustments with the Twin Tuner EX are only allowed above 60% throttle position or 5000 RPM. You can add or subtract fuel. Installation takes only 10-15 minutes and is very easy, with no splicing, cutting, crimping, or bulky interconnections. All access is at the Delphi® ECM. Just remove five wires from the ECM connector, insert these wires into our small mating connector, insert five new wires from the Twin Tuner into the ECM connector, and connect one ground wire. The unit is completely encapsulated and impervious to moisture. With a very low profile of only 1/2” and occupying a fraction of the space required by competitive products, you won’t have a problem finding a place to mount the unit. 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 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.
