Is the ELM actually connecting the the cars ECU? Have you tried checking the return value from myELM327.begin() to ensure it correctly initialised?
By default protocol is chosen automatically, so the elm should connect to the car.
The last picutre is with the debug mode on /myELM327.begin(2000, true)/. I usually get ELM_TIMEOUT response when the elm has trouble connecting to the car.
