what do power commanders do for motorcycles

Power Commanders are aftermarket fuel management systems that significantly improve motorcycle performance and drivability. They achieve this by allowing precise adjustments to the air/fuel ratio across the entire RPM range. This article will delve into the specifics of how they work, their benefits, and considerations before installing one.

Understanding Your Motorcycle's Fuel Injection System

Before understanding Power Commanders, it's crucial to grasp how a motorcycle's fuel injection system operates. The system's primary goal is to deliver the optimal amount of fuel for efficient combustion at various engine speeds and loads. This is managed by the Engine Control Unit (ECU), which uses sensors to determine the required fuel quantity.

However, modifications like aftermarket exhaust systems, air filters, and camshafts can disrupt the carefully calibrated air/fuel ratio. This imbalance can lead to poor performance, reduced fuel economy, and even engine damage. This is where a Power Commander steps in.

How a Power Commander Works

A Power Commander sits between the motorcycle's ECU and its fuel injectors. It intercepts the fuel delivery signal from the ECU, allowing you to adjust the fuel amount delivered to each injector at various points in the engine's RPM range. This is accomplished using a handheld programmer and software that lets you create custom fuel maps.

Key Features and Benefits of Using a Power Commander

Performance Enhancement: By optimizing the air/fuel mixture, a Power Commander can unleash significant horsepower and torque gains, particularly noticeable after modifications.
Improved Throttle Response: A leaner or richer fuel mixture can negatively impact throttle response. Power Commanders help maintain optimal fueling for improved responsiveness.
Smoother Running: Addressing fueling inconsistencies across the RPM range can result in smoother engine operation, minimizing hesitation and rough idling.
Eliminates Backfiring and popping: A properly adjusted fuel map can eliminate backfiring often caused by an improperly tuned air/fuel mixture.
Compatibility with Modifications: Power Commanders are essential for maximizing the benefits of performance upgrades like aftermarket exhausts and air filters. They compensate for the changes these modifications make to the intake and exhaust systems.
Customization: They allow fine-tuning for individual riding styles and preferences. You can adjust the fueling map based on your specific needs and riding conditions.

Choosing the Right Power Commander

Choosing the right Power Commander depends on your motorcycle's make, model, and year. Different models are designed to work with different bikes. Consult the manufacturer's compatibility chart to ensure you're getting the correct unit. You'll also need to consider the level of adjustability you want. Some offer simpler adjustments while others provide more granular control.

Installation and Tuning

While many experienced motorcycle enthusiasts perform Power Commander installations themselves, it's important to note that improper installation or tuning can negatively impact your engine’s health. The initial installation is straightforward but requires some mechanical aptitude. However, precise tuning of the fuel maps generally requires access to a dynamometer for accurate measurement of air/fuel ratios. This ensures optimum performance without risking engine damage.

Alternatives to Power Commanders

While Power Commanders are extremely popular, other fuel management systems exist. These include auto-tuners, which automatically adjust fuel maps based on sensor data. They're more convenient but can be more expensive than traditional Power Commanders.

Conclusion

Power Commanders provide a powerful and effective way to optimize a motorcycle's fuel delivery system, enhancing performance, drivability, and overall riding experience. However, they require careful consideration and often professional tuning to fully realize their potential and avoid potential engine damage. Remember to always prioritize safety and consult with experienced mechanics when undertaking motorcycle modifications.
