Are you working on the new Yamaha MY2021 and later models?
Do you need to disable certain functions on your customers’ bikes for racing or customization purposes?

Thanks to the latest developments from our team, it is now possible to perform deactivations on Yamaha models equipped with the Bxx-8591-xx ECU without compromising cruise control functionality.

This update enables the precise and safe deactivation of several electronic management controls, including:

• Lambda sensor exclusion
• Rear Lambda sensor exclusion
• Evaporative emissions purge valve exclusion
• Wheel speed sensor exclusion
• Catalyst exclusion
• Secondary air injection system exclusion
• Exhaust valve exclusion
• Immobilizer exclusion
• Lambda control deactivation
• ECO mode deactivation
• Decel fuel cut deactivation
• Power restriction removal
• Rev limiter removal

WARNING: The above deactivations are strictly for track use only.
WARNING: Some models may not include all the listed deactivations, as certain functions may not be provided by the manufacturer from the outset.
