Adjusting Your Power Commander: Changing The Fuel Map

The Dynojet Power Commander is a powerful device that can be used to optimise your vehicle's air/fuel ratio. It is a plug-and-play kit with preloaded maps that can be modified without the need for a computer. The Power Commander Fuel Controller allows users to select between a Power Commander FC Map, custom-built maps, or fine-tune low, mid, or high rpm ranges while sitting on the bike. It is compatible with various vehicles, including Harley-Davidson and select Japanese and European units, and offers a range of features such as fuel and timing control, warm-up fuel adjustment, and gear/speed input. The Power Commander can be used to improve your vehicle's speed, power, and performance, and is a popular choice for those looking to enhance their riding experience.

The Power Commander Fuel Controller: a simpler, less expensive option

The Power Commander Fuel Controller is a great option for those who want basic fuel tuning capability without the high cost. It's a plug-and-play kit with preloaded maps for your vehicle that can be modified on the fly, and it doesn't require a computer. This device is small, lightweight, and easy to use, and it can be fitted to any bike.

The Power Commander Fuel Controller gives you three options to choose from: the Power Commander FC Map, custom-built maps, and the ability to fine-tune low, mid, or high rpm ranges while sitting on the bike. With the supplied Control Center software, you can make adjustments in standard +/- 10% increments from the selected map settings, and different ranges are also available.

The Power Commander Fuel Controller is pre-programmed with PCFC Power Maps specific to the make and model of your vehicle. You can also load up to 10 of your own custom Power Maps into the device and switch between them without needing to "re-boot" with a computer. This gives you the ability to fine-tune your vehicle's performance to your exact specifications.

The software is also compatible with Power Commander, allowing you to download Power Commander maps to the Power Commander Fuel Controller. This device is a cost-effective and flexible solution for those who want to optimise their vehicle's performance without breaking the bank.

If you have a unique setup or are looking for live tuning, you can also consider the optional Auto Tune module with a wideband O2 sensor. This will allow you to tune your vehicle in real time and make adjustments as needed.

How to load a map: a step-by-step guide

Step 1: Open the Power Commander Control Centre Software

This software will allow you to load and select your desired map. You can connect the Power Commander to your computer via USB.

Step 2: Click "Load File"

This will allow you to browse your computer files and select the map you wish to load.

Step 3: Select a Map

Choose the map that corresponds to your vehicle's make and model, and any modifications you have made. You can either use a pre-loaded map or a custom-built map. If you have made major modifications to your vehicle, you may need to have a custom map built by a Power Commander Tuning Centre.

Step 4: Click "Open"

Once you have selected your desired map, click "Open" to confirm your selection.

Step 5: Click "Upload"

With the Power Commander powered up, click "Upload" to begin loading the selected map onto your device.

Additional Tips:

• You can load up to 10 personally built Power Maps onto the Power Commander FC and switch between them as desired.
• The Power Commander FC allows you to fine-tune low, mid, or high rpm ranges while sitting on the bike without needing to connect to a computer.
• The Power Commander cannot damage your ECU as it is designed not to send current to the processor.

The Power Commander cannot damage your ECM/ECU

The Power Commander is a useful tool for those who want to adjust their fuel curve to match the air curve in their engine. This can lead to a noticeable increase in horsepower, particularly in the part-throttle areas where most riders spend a good deal of time. However, it is important to note that the Power Commander cannot cause your engine to pump more air. The modifications you make to your engine to pump more air are limited if you cannot adjust the fuel curve accordingly.

While some dealers may claim that a Power Commander can "fry" an ECM, this is typically just watercooler talk. In fact, one user on a technical discussion forum reported that they had installed dozens of Power Commanders and only encountered two defective units. In that case, Dynojet, the company that makes the Power Commander, took care of the issue and sent a previously tested unit that worked fine.

It is also worth noting that the Power Commander does not interfere with the bike's ability to compensate for atmospheric conditions. The Fuel Injection Systems found on today's bikes do a good job of adjusting fuel for air temperature, altitude, and other factors. The Power Commander does not interfere with this automatic compensation.

The Power Commander cannot void your warranty

The Power Commander is a plug-and-play kit with preloaded maps for your vehicle that can be modified on the fly, without the need for a computer. It is a simpler, less expensive option for those who need basic fuel tuning capability. The Power Commander Fuel Controller allows users to select between a Power Commander FC Map, custom-built maps, or fine-tune low, mid, or high rpm ranges while sitting on the bike.

Now, regarding the question of whether the Power Commander can void your warranty—the answer is no. Here's why:

In most cases, for a manufacturer to deny a warranty for a failed component, they must prove that the aftermarket part caused the component to fail. The Power Commander is designed so that it cannot send current to the processor in the ECU (Engine Control Unit), which means it is highly unlikely to damage the stock system in any way. This makes it legally challenging for a vehicle manufacturer to void the warranty due to an aftermarket part unless they can provide clear evidence that the aftermarket part directly caused or contributed to the vehicle's failure.

However, it is important to understand that while the Power Commander itself might not void your warranty, any issues specifically attributed to its use may not be covered. For example, if your engine experiences problems and the Power Commander is deemed the cause, repairing the engine would not be covered under warranty. Therefore, it is generally recommended to consult with performance-oriented dealerships that have experience working with customers who have similar aftermarket modifications. Additionally, removing the Power Commander before taking your vehicle for service can help avoid potential issues with warranty coverage.

In summary, while the Power Commander is a useful tool for basic fuel tuning, it is essential to recognize its potential impact on warranty coverage. By understanding your rights as a consumer and taking necessary precautions, you can ensure that your vehicle's warranty remains intact while still enjoying the benefits of the Power Commander.

If you can't find a map for your combination, use a map for a similar set-up

If you can't find a map for your combination, you can use a map for a similar set-up. This is recommended if you have minor modifications, such as an exhaust, air-box, or mild cams. However, if you have major modifications, like ported heads, aggressive cams, or a stroker, it is advisable to have a custom map built by a Power Commander Tuning Centre.

• Open the Power Commander Control Centre Software.
• Click "Load File".
• Select a map that is similar to your set-up.
• Click "Open".
• With the Power Commander powered up, click "Upload".
