We are pleased to announce we now have found a reliable platform for ECU flashing. There are many advantages as In the old days it was a case of putting on a Dynojet PowerCommander (or other piggy back fueling device) and adjusting the fueling, these days it’s not just fueling that is the issue when you change the exhaust pipe there are so many gains to be had from flashing your bike ECU tuning. Nowadays it's the only way to not only fuel the bike but at same time remove those horrible emissions based restrictions built into the bikes electronics.

For example a common issue customers of new bikes experience is a “snatchy throttle” or a on/off/on throttle feeling that “feels like a lightswitch”, well that is because manufacturers are forced to put catalytic conveters on the bikes and have to power off the injections on closed throttle positions to ensure there is no fuel passing into the exhaust on deceleration that will then potentially melt the catalytic converter. Once the catayltic converter is removed we can disable the injectors being powered off and smooth that throttle response. Many modern machines have fly by wire throttle and manufactures use this to restrict these bikes in 5th and 6th gear. Below is a before and after flashing and some fueling work trace from our dyno today. Frankly we were astonished with the results on this Yamaha MT09.
