I can get car scanner to connect using the K line protocol on my 2003 Hybrid, but the data available is a very limited list of standard OBD information. Revs, coolant temp, throttle position, IAT, MAF, fuel trim and O2, off the top of my head.
Torque pro seems much more customisable, but as yet I haven't struck it lucky by finding custom PIDs to get at what I really want - live hybrid data. I've tried different versions from similar vintage Prius and Lexus RH400 models with nothing working so far. My googling suggests nobody else has had any luck using anything other than techstream on the early hybrid.
