Using a Power Commander fuel-injection controller to alter a motorcycle's fuel curve at low, mid and high rpm ranges can make significant performance changes, increasing and smoothing power delivery on the road. These changes are normally made using special software to program the Power Commander, but you can also program them manually using the buttons on the Power Commander's faceplate. Although these buttons do not provide an extensive range of options, they allow you to do enough to fine-tune a motorcycle for changing riding conditions.
Instructions
1. Remove the seat to access the Power Commander unit, using the seat release mechanism or by unbolting the seat with an Allen wrench.
2. Hold down all three buttons on the Power Commander's faceplate and turn the motorcycle's ignition on. Release the buttons once the LED bar graph on the faceplate illuminates completely once.
3. Press the left button once to select the low-range rpm fuel settings. A single LED bar will illuminate, denoting the current setting level. Press the button once to increase the fuel curve by one bar. Hold the button down to decrease the fuel curve by one bar.
4. Press the center button to select the mid-range rpm fuel settings or the right button to select the high-range rpm fuel setting. Adjust the fuel curve as needed, following the same method used to adjust the low-range rpm fuel curve.
5. Wait for 20 seconds to exit the programming function without pressing any of the buttons. The graph position illuminated on the LED will shift from the current setting to the lowest bar, indicating that the programming has ended.
6. Turn the ignition switch off.
