![]() ![]() ![]() Removal of top speed limiters are for racing use only. Spears Racing’s Flashed ECU Flashing 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. 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 Flashed ECU by Spears Racing. need to test more.Motorcycles today are being restricted more by software than they are by hardware. Best I would get before was 3.7lp100 being super care full all highway. (do you really need do go that fast? get a road bike.)įuel consumption, sitting at 4.5L/P100 over 313km of city and highway giving it the beans a few times here and there, Filtering to the front at the lights and zipping away. previously only got to 205 on a long stretch. I am yet to test if I can get up past 208. ![]() No way it got up that far that fast before. Where I really noticed the tune change was on the single lane highway, cars in front doing 90, dropped down the 2nd gear, pinned it, over take 5 cars, look down pulling back in doing 195 on the dash. Making it much more like my old DL1000 for cruising, 3500rpm-ish at true 100kmph (109 on the dash). The day after the tune (still not 100% finished as there is still a on/off throttle <5%) I changed to 18T front and 42 rear sprockets. So at light throttle cruise the DL was seeing as lean as 17:1 afr. The euro 5 emissions requirements are tested at 100kmph cruise. They also may be willing to offer a product that may not have as long a lifespan as we expect the 1050 to have - what, maybe 200,000 miles? Would be great to know what KTM's tuning parameters are to get such strong hp/ltr levels while still achieving Euro 5 compliance - compression ratios, intake/exhaust flow levels, timing, AFR's, throttle restrictions, etc. KIM'S 1290 is Euro 5 compliant, so what do they do to get 20% more hp per litre? It is very interesting how KTM gets 160hp from their 1290SAS motor. The Euro 5 standards are really restrictive and do not place performance as any kind of priority they are really a stop-gap measure to keep ICE in service until electric vehicles can be mandated into place. If AFR's are extremely lean for emissions, timing is being retarding, and throttle plate restrictions, and exhaust and intake restrictions are preventing optimum positions to allow maximum airflow, stoichiometric mixtures and the optimal performance of the internals, the result is what we are getting today. ![]()
