Hey Guys,
The amount of data that can be retrieved is partially governed by the level of compliance to the OBDII standard your Liberty has been built to, so I can only assume that the more modern your model, the better compliance and hopefully access to more data ?!?
Yes, their website is quite generic in regards to info and I can only assume that it's because this software is made to talk to a vast array of makes and models of vehicles.
Easiest way to answer your questions is if you post your email address here and I'll happily send you the user manual in pdf format and that way you can see the features and screenshots etc......
Cheers,
Lok
