Not sure ive seen a list just info ive picked up over the years. There cheap enough and wont damage your ecu mate. Even the cars that would not show live data displayed fault codes.

Cheers Ferret I bought one and used it when the engine was on to check something and it worked fine but just wondered if it would be ok for testing something as a passenger while wife was driving.
