The stock ECU in your motorcycle is far from optimized even if your motorcycle is stock. 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 results of this conservative programming are a compromise in performance and running condition of your motorcycle.

Description

Motorcycles today are being restricted more by software than they are by hardware. 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.

The stock ECU in your motorcycle is far from optimized even if your motorcycle is stock. 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 results of this conservative programming are a compromise in performance and running condition of your motorcycle.
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 ECU does this by monitoring inputs from throttle position, rpm, gear position, intake air temperature, air temperature and coolant temperature.

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. Raise or remove limiters. Removal of top speed limiters are for racing use only. 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.
Essentially, 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).
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. The new performance map is then uploaded back into the ECU.
Your acceleration from the stock to the new flash will be noticeably faster and smoother,this is do to the efficiency of air fuel.

 

 

The Spears Racing Yamaha YZF-R3 ECU Flash not only corrects the issues in the stock ECU base map that are to blame for the hesitations in the midrange, it includes all of the improvements listed below here are the changes:

Remove all timing based restrictions
Remove all speed and gear based restrictions
Customized ignition mapping (for premium pump gas)
Reduced engine braking
Disabled the OEM algorithm linking ignition timing to coolant temp
Disabled the OEM Air Injection System (AIS)
Disabled the OEM closed loop O2 sensor system
Disabled the OEM injector deceleration cut
Disable fuel injector cut
Disable immobilizer
Disable stock O2
Adjustable radiator fan temps for more efficient cooling
Raise rev limiter (this is critical for racing, as you can now shift above 12500k and stay in the power band)
While this Yamaha YZF-R3 ECU Flash will definitely open up extra top end power along with the mid range power and torque.
Yamaha YZF-R3 ECU Flash’s biggest improvement is actually in the midrange where you feel it driving off the corner. The bike revs are considerably faster, with increased torque, as well as the increased top end horsepower. We’ve seen gains so far of no less than 2.0-5.0 RWHP and 1.5-3.0 ft.LBS of torque across the entire power band.

 

Unleash up to 15% more power

Increase Acceleration & Top Speed

Lots more low/mid torque

Improve Throttle Response & Control

This Yamaha YZF-R3 ECU Flash has eliminated several of the OEM restrictions, that will take your commuter feeling motorcycle to a bike with an attitude. The bike will now rev to a higher RPM, and allow more timing into the power rev range and of course more fuel, which means more power with the right combination.

You still may want to fine tune your bike with a piggyback fuel controller, since every bike, exhaust and air intake is slightly different,but it isn’t necessary our tuning is much more accurate than any “Library Maps” you can download online.

The hardest thing to installing a flashed ECU is removing it from your motorcycle,Just unplug your stock ECU, and plug in the flashed ECU. That’s it! Same day Turn around.
