Tweaking PC3 for Increased Horsepower

 

This by far has to be one of the most controversial topics when it comes to increasing horsepower gains using the Power Commander III.

What are the 3 buttons for, how do I used them, and should I be messing with them. All very good questions.

 

There are many who believe that the three buttons on the PCIII do absolutely nothing and the gains when tampering with these buttons are purely psychological. On the other side of the spectrum you have those special individuals who believe that these buttons work, but tinkering with them, specifically  your air to fuel ratio, should be left to a trained professional sitting behind a dyno tuner. I have to disagree with both and believe that Dynojet knew exactly what they were doing when placing these buttons on the face plate for the consumer to tinker with on the fly. No one knows your bike better than you and just like you know or feel when there is an issue, you will also notice when there is a performance gain despite what other may say.

For those interested in adjusting your PC III blind and on the fly I'm including the directions below for you review and knowledge. For those interested in the sweet spot that I found to work best for me, take a looks at my YouTube tutorial and pay close attention to the level adjustments for each and make your adjustments accordingly. When performing these adjustments blind and on the fly take note that with each minor adjustment, you're going to need to take your bike out for a tet ride to see what works best for you.

Tweaking PC3 for Increased Horsepower

To adjust the buttons on the faceplate of your Power Commander III, follow the instructions below:

-With the ignition off, hold down all three buttons on the Power Commander III unit.

-While still holding down the buttons, turn on the ignition and start the bike.

-Release buttons. The light(s) should show up in the last place they were left, by default the center two lights.

-Select the range you wish to adjust: Low, Med, High by pushing the corresponding button once, (these ranges are determined by taking the bikes RPM limit and then dividing it into thirds).

-At this point holding that button down will move the lights down (leaning out the mixture).

-Pushing the button repeatedly will move the light up (richening the mixture).

-When the two center lights are lit up this is the “0” setting.

-After making your adjustments wait 20 seconds before turning it off. This allows the settings to be saved to memory.
