The impulse to tune an ECU starts with a desire for more horsepower. Most ECU tuning is intended for track use and likely to leave your bike out of compliance with emissions regulations. Before going ahead with any modifications, carefully consider any impact on your motorcycle warranty and emissions compliance.The cost to reflash an ECU is between $250 and $350 the cost to install and dyno tune a piggyback module like Power Commander can run $700 to $800 on top of the cost of the module itself.These devices improve fuel delivery, but do not alter ECU mapping tables, consequently overall performance improvements are limited. If an ECU tuning option is not available for your motorcycle, then the best fallback is to install a piggyback module such as a Power Commander from Dynojet or the EVO from Rapid Bike.

Expect smooth throttle response and predictability across the power band, longer engine life, lower operating temperatures, and yes more horsepower.Call and talk to at least two tuners before going ahead. Carefully choose your ECU tuner, they are not all the same and the outcome depends on multiple factors, not the least being competency and experience.Re-tuning the ECU is a must when running aftermarket exhaust or air intake systems to adjust fuel mixture to match improved airflow.(Just a reminder, American Sport Touring does not accept endorsement fees or compensation of any kind from those who contribute.) Six Key Takeaways For balance, we also listened to feedback from riders. To get a complete picture, we spoke with several major tuners, and had an in-depth conversation with Nate Phipps at 2 Wheel DynoWorks. This article explains how to go about modifying your ECU safely and what to consider before going ahead. Which is why experienced riders seek-out ECU modifications to put more of that control directly in their hands. In fact, the ECU, not the rider, has the final say about throttle response. This amazing device is known as the Engine Control Unit or ECU for short. A device that listens to throttle inputs and then translates them into signals that control engine performance.

An additional internal mod was engineered to cut down on what small amount of decel pop remained after installing a PAIR cap.Įliminates Internal Fuel Cut for smoother open/shut throttle operation at higher RPMs.Hidden under the fairings of your sport touring motorcycle lies an electronic marvel that can best be described as an ever present, always rational, never flustered, copilot. (Eliminates small peak power loss experienced from removal of the flies.)Īllows throttle plates to fully open at 3200 RPM in High Power modes with flies installed. Overrides the ‘Safety Mode’ with the flies installed. Some of the benefits of re-flashing your ECU are:Īllows Traction Control Mode to be adjusted/turned off ‘on the fly’.Īllows the last selected Traction Control Mode to be retained after the bike is shut off, thereby eliminating the need to remember to turn it off before your next pass. The results of this conservative programing are a compromise in performance and running condition of your motorcycle.Īchieved by correcting the stock ECU’s deficiencies and tuning the engine to take full advantage of all of its potential. The program in the stock ECU’s have been developed to suite a wide range of riding conditions and riding skill levels also wide range of fuel types and grades. The stock ECU in your motorcycle is far from optimized even if your motorcycle is stock. The ECU does this by monitoring inputs from throttle position, rpm, gear position, intake air temperature, air temperature and coolant temperature . The ECU controls the amount of fuel, ignition timing, RPM limiters, Top speed limiters, Power Mode, Traction Control and other parameters of your motorcycle.
