Unlock Bosch Gen4 Performance Line CX Motors – EBT Unlock Key
Maximize the potential of your Bosch Gen4 Performance Line CX motor with browser-based tuning. If your motor uses the classic BES2 system (round charging port, Intuvia, Purion, Kiox displays), you can safely and securely unlock higher speeds using only a USB cable and browser.
Important: Only Bosch Gen4 BES2 motors (not Smart System BES3) are compatible with the EBT Unlock Key. Always check your motor version before unlocking.
