they can be used on any bike that supports the tuners, however their functionality is limited to reading and erasing diagnostic codes and reading map info. They cannot be used on any other bike once they've been plugged into an ECM for any tuning functions whatsoever. They are paperweights. I have 3 of them myself.
I was gonna get one TTS and put both bikes on it but i will just use what i have since the tuner told me the super pro race tuner and the PC111 on my stock RG will work fine i will just save some money.
