I am having trouble starting the engine when the power commander is installed, what should I do?
Most Power Commanders are powered by the injectors on the bike. When you turn the key on, the fuel pump gets power and primes the fuel circuit. When this happens, the injectors get power, and the Power Commander also gets power and lights up. After a few moments, the fuel pump has pressurized the system, and usually shuts off. If the fuel pump shuts off, the injectors’ loose power, and the Power Commander shuts off. If you attempt to start the bike when the Power Commander is off, the bike may take longer to start than normal, until the fuel pump comes back on. The fuel pump may come on instantly, after a few engine revolutions, or on some bikes seemingly not at all. If the fuel pump does not come on, the bike will not start. They recommend starting the bike once you turn the key on. Do not wait for the fuel pump to shut off, or a check engine light to go out.

What is konck, detonation and pre-ignition?

• Detonation is an uncontrolled combustion event which occurs after the spark event.
• Pre-ignition is an uncontrolled combustion event which occurs before the spark event.
• Knock (pinging) is the actual noise that can be audibly heard if detonation is bad enough. Most OEM knock sensors are basically microphones tuned to listen for a specific frequency to detect this noise. When some is describing knock, they are generally referring to detonation.

My engine makes a popping noise on deceleration, how do I get rid of this?

• For older Magnetti-Marelli fuel injected bikes, adjusting the fuel table to remove fuel can help reduce popping. Highlight the zero percent column from 2,000 rpm to redline and enter in values from -40 to -50. Run the bike and see if the popping has reduced. Sometimes, the throttle position may not show zero at idle and should be correctly adjusted with the bike at full operating temperature to make sure it is reading zero.
• On newer Delphi fuel injected bikes, they have found that adding fuel is needed to reduce popping. Highlight the zero percent column and instead of using negative numbers, try adding fuel to the map. Start with putting a value of 25 in the cells and see if the popping has reduced.
• Adjusting the ignition table could also help in deceleration popping. Advance the timing in the zero percent column 3 to 5 degrees to see if popping has been reduced.
