The new performance map is then uploaded back into the ECU. The most effective change to this flash is the maximizing the low to mid torque numbers to to effect the overall performance run time from the beginning to the rev limiter,this will give you success to your racing efforts.
After Spears Racing has flashed the ECU of your motorcycle you will see the improvement in dyno numbers, top speeds as well as overall running condition of your motorcycle.Įssentially, our Yamaha YZF-R3 ECU Flash Reprogramming service delivers a bikes engine as the manufacturer designed it originally, after countless hours and hundred of dyno pulls to establish baseline performance we suck the stock map out, switch off anything we feel that’s causing a problem adjusted and trim air fuel/timing to achieve the maximum torque and HP for a stock bore Yamaha YZF-R3 (air filter/exhaust etc). Removal of top speed limiters are for racing use only. Spears Racing’s Yamaha YZF-R3 ECU Flash will correct the stock deficiencies and program the fuel and ignition maps to best suite what has been done to your motorcycle. The ECU does this by monitoring inputs from throttle position, rpm, gear position, intake air temperature, air temperature and coolant temperature. The motorcycle ECU controls the amount of fuel, amount of ignition advance, RPM limiters, Top speed limiters, Power Mode, Traction Control and other parameters of your motorcycle. The results of this conservative programming are a compromise in performance and running condition of your motorcycle. 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.
#ECU FLASH MOTORCYCLE SOFTWARE#
This means we are re-writing the software inside the motorcycles ECU to remove these restrictions and properly tune every aspect of modern motorcycles, such as fueling, timing, throttle mapping, individual gearing, cylinders, modes, speedometers, fan temps this is done by using the Yamaha YZF-R3 ECU Flash by Spears Racing. Motorcycles today are being restricted more by software than they are by hardware. Donino XM2 Adjustablle Race Throttle Assemblies.
