Hello guys! I'm from Finland, so I'm writing this in English.
I was test driving my bike with the usb key so I could go 70km/h. Everything was going well but then when I stopped driving for few minutes and tried to drive again the usb key did not work at all. Currently it is not working is there any solutions how can i unlock the speed again?

Could someone please answer?

Sorry eetu, I 'm not sure if anyone else tried this stick. Did you proof contact and cable? Is there a possibility to reset the ECU/controller?
