SBU Professional ECU Flash Service 
Yamaha YZF-R9 (2025-2026)

This ECU flash will completely re-tune your OEM ECU to maximize performance while maintaining OEM-levels of reliability. We achieve this through removal of all restrictions, optimizing of all pertinent mapping and custom tuning. We typically see 10+ rear wheel horsepower at the wheel with this service, on an otherwise stock electronically Yamaha YZF-R9. Expect incredibly strong power throughout the entire rev range like you've never felt before. 

There may be less expensive flashing services out there, but what sets us apart and makes our flash such an excellent value is the extensive dyno testing and professional race development we have done. Most other providers of these types of services are using generic mapping that leaves a lot of power on the table and compromises the overall smoothness of the motorcycle. We've spent countless hours on R&D and dyno development and the end result is the flash we offer.  

As development continues, we will offer free updates to customers, you only pay shipping.

PLEASE NOTE: This is a mail-in service, your ECU must be removed and shipped to us. Once you've completed your purchase a registration form will be e-mailed to the address provided and will contain the questions regarding bike modifications as well as shipping instructions. This form is required.
