![]() It's crucial to consider the implications of intake and exhaust changes. Tuning a fuel-injected motorcycle is not limited to optimizing performance modifications. Alternatively, there are DIY kits available for self-reflashing, but caution is advised as making incorrect changes could damage your engine. If a licensed service center is not close by, you may need to remove your ECU and send it in for flashing, which can result in downtime for your bike. However, getting an ECU flash may not be as readily available for all motorcycle models, primarily limited to Japanese sport bikes. The absence of additional wiring or hardware installations makes the process more streamlined. A flashed ECU can adjust not only fuel and ignition control but also other parameters like removing speed limits, altering rev limiters, and adjusting fan controls. This method offers a more comprehensive and advanced tuning solution compared to a Power Commander. Flashed ECUįlashing the ECU involves rewriting the code within the ECU itself to optimize the engine's performance. On the positive side, it can be easily removed, allowing you to revert to stock settings. However, installing a Power Commander can be labor-intensive, requiring the removal of bodywork and tanks. Additionally, there are numerous alternative maps available to match the specific modifications made to your motorcycle. The Power Commander comes pre-programmed with a base map for your bike, making the initial setup hassle-free. It offers a relatively straightforward solution for tuning and is compatible with a wide range of motorcycles. Installation involves plugging the Power Commander's wiring harness into the fuel injectors and other sensors of the bike. The Power Commander is a piggyback module that works by manipulating the stock ECU's signals to achieve desired changes in fuel and ignition curves. Each method has its own set of advantages and considerations. When it comes to tuning a modern EFI bike, You have two primary options: installing a Power Commander or opting for an ECU reflash. Tuning your bike not only enhances performance but also ensures the engine runs safely without running lean, which could cause overheating and engine damage. However, modifications such as aftermarket exhaust systems, high-flow air filters, or engine enhancements like big bore kits or camshafts necessitate adjustments to the fuel and ignition timing. Stock motorcycles are designed with government regulations, liability concerns, and reliability in mind, which means they may not perform to their full potential. Most riders Seek more power and improved throttle response, both of which can be achieved by optimizing the fuel and ignition curves of the bike. Why Tune a Fuel-Injected Motorcycle?īefore we Delve into the specifics of tuning options, let's understand why tuning a fuel-injected motorcycle is essential. Therefore, it's crucial to research and comply with local laws and consult with your dealer before proceeding with any modifications. Additionally, they may void your factory warranty. Before we dive in, it's important to note that both Power Commander and flashed ECUs are generally illegal for road use as they can alter your engine's exhaust emissions. In this article, we will explore the technology behind these tuning options and provide a comprehensive analysis of their pros and cons. When it comes to optimizing the performance of a fuel-injected motorcycle, there are two main options available: installing a piggyback module like a Power Commander or having the ECU reflashed by a company like Flash Tune. Tuning a Fuel-Injected Motorcycle: Power Commander vs. Power Commander Installation and Operation.Effects of Intake and Exhaust Modifications.But the subject went away as newer models were released.Unlocking Your Engine's Potential: ECU Reflash vs. Hydraulic clutches were a popular topic here for a while, with posters producing lists of the parts needed to change a cable clutch to hydraulic. Finally the fluid in the reservoir tended to quickly get dirty, apparently from grime around the front sprocket. Also, as I recall, there was an issue with fine bubbles in the line due to vibration. So if it was broken, you had to replace the entire M/C assembly. One thing that wasn't liked was that the reservoir, probably a $15 part, wasn't sold separately. If I read between the lines, it sounds like the owner feedback was poor so they dumped it. ![]() The clutch is now directly operated by a cable instead of a hydraulic system, improving feel and feedback to the rider as well as reducing weight. ![]() In 2009, when they went back to cable, they said: New self adjusting hydraulic clutch minimizes changes in clutch feel over a long race. In 2007, when it was introduced, Suzuki said: "Why did they use hydro clutches on 07-08?"
