I can confirm you that pin 7 is connected and used.

If the OBD is not connected to car (not powered), please don't connect it to the LCD shield.

Maybe you can try on a new car to eliminate the possibility of malfunctioning of the adapter.

The 5V is not picked from Arduino. It's converted and regulated from the 12V. The 5V is for powering Arduino.

When you update the firmware, don't connect any OBD device to the emulator.

The repository of the sketch for kit #2 and kit #3 is here:

Gyro data and temperature data are not logged in the sample sketch, though they are retrieved. Take a look at the code please.

The OBD-II adapter is not firmware upgradable.

Does your system has a new COM port when plugging the emulator?

Sorry, I misunderstood your point. Yes all modes are supported by the emulator.
