Some of the free apps I've found will allow one to set the Mode/PID manually. If you know the "address" of the variable, you can read it. Can't remember off the top of my head if the cam and crank sensor Mode/PIDs are published. They may be part of the standard PIDs, which means you should be able to select them from a list in the app. You may be able to figure it out at the OBD/CAN Wiki in my sig.
