ECU Re-Flash

What if you could unleash the hidden potential of your motorcycle?

As many of you already know, the performance of most modern day sport bikes is watered down, so to speak. The manufactures are required to do this for several reasons such as emissions, noise and speed legislation, as well as rider safety concerns. We believe that some of these measures are understandable and even appropriate considering the popularity of these motorcycles with inexperienced riders. However, the fact remains that the OEMs (Original Equipment Manufacturers) are unable to provide an economical way for a builder or racer to remove these restrictions.

In our own quest to provide optimum performance to our customers we did some research, and we are pleased to announce the development of a new service for our track day and racing community. This new service consists of a Re-flash of your stock ECU in order to unlock all of your bikes potential. The process is simple: Send your ECU to JETT TUNING and we will send you back your ECU Re-Flash. (This is not an exchange)
