![]() The bike will need a flashed ECU, which may or not result in the bike being returned to its original value. A Power Commander can be easily removed and sold secondhand for good money. It is harder to get your ECU flashing money refunded. You have the option to adjust your idle speed, use quickshifter functions, or even access datalogging and bypass functions for the immobiliser. You can adjust the fan speed, bypass sidestand switches and clutch switches, change rev limits and use more extreme ignition timings to match high-octane fuel. You can control the opening characteristics of secondary throttle valves like a GSX-R and Hayabusa. PAIR fresh air injection can be inserted into the exhaust ports or the EXUP operation. These restrictions can be removed by flashing the ECU. The ECU will not open certain gears completely if the throttle plates are restricted. This restriction may be found on some bikes. You can adjust the speed at which throttle plates open relative to twistgrip on Ride-byWire bikes like Yamaha’s Yamaha R6 and Yamaha R1. This means that we can program not only fuelling parameters but also any other control that the ECU has. Woolich Racing has developed tools that allow us to access the ECU of modern bikes. ![]() There is no other way to access sealed ECUs than factory procedures or high-end hacking methods. Many of the major bike manufacturers use closed, proprietary fuel injection systems. Cars have historically had simpler ways to connect to ECUs than bikes. ECU flashing is more common on cars than it is on bikes. A method to connect a computer or laptop with the ECU. However, we still need some specialized kit. Instead, we use EEPROMs or similar types of memories. Today, UV lamps are not required to reprogram memory chips. Flashing them – physically placing them under ultraviolet light to erase them – allows a new program to be placed onto the memory. Flashing is the name of the process, as EPROM (Erasable Programmable Read Only Memory) chips were used in computers back in the old days. ![]() This involves actually editing the control program that is on the bike’s standard ECU and then uploading it to the memory. This brings us to the second method for fuelling tuning: re-flashing your ECU. There are some limitations and things that you can’t do with a computer. A Power Commander allows for great fuel control and can adjust to a variety of engine tunings. A Dynojet Dyno and control software allow a tuner to quickly and easily adjust the fuelling at any engine speed and through a variety of throttle openings. These tiny boxes intercept the injector signal from an engine’s Electronic Control Unit, (ECU), and alter the duration before it is passed onto the injector. ![]() The traditional method of adjusting the injector duration on bikes was to use an aftermarket fuel-injection computer like the Dynojet Power Commander. This allows you to change the amount of fuel that is being put in. You can adjust the time the ECU opens fuel injectors. These small tubes of brass had precise holes that allowed the fuel to flow through the tubes. You’ll likely need to modify the fuelling to ensure your engine receives the correct amount of fuel throughout the BT Moto.Ĭarburettors required that the jets were physically changed. ![]() You can modify the exhaust or airbox, change the cam timing, or fit a turbocharger. Tuning involves changing the fuelling of engines. This is the most recent in fuel-injection tuning and they have been doing it for years with cars. ![]()
