In the continued developing of the Hill Power Racing ECU/EFI mapping service we have come up with significant improvements to the stock mapping on many bikes. We have settings custom designed for each application.

Our aim is to increase tractability and to pull longer in each gear, reducing wheel spin and arm-jerking power helps the bike accelerate quicker and reduces rider fatigue.
You can also have a tailored map created for you here at our test track, please call for more details.
