GM have updated techline connect again and found a way to lockout clone mdi and mdi2 devices.
I tested what would happen if a clone device was used and it is a bit of a nightmare, It will let you login and do one programming session, once you quit techline it locks your account so you can no longer launch techline at all.
The resolution required multiple emails and phone calls to the ebusiness helpcenter to get my account unlocked and was advised if I use the clone device again it will be locked again and i will nnot be able to unlock it.
Use a clone on techline at your own peril now
