Please at least share your sketch so that we can know what you are doing wrong.

To query a specific PID, make sure to terminate the command with \r. So it should be "0101\r". The code is like this: char buffer[64]; obd.write("0101\r"); int bytesReceived = obd.receive(buffer,1000); if bytesReceived is greater than zero, buffer has the response string and all ...

Thank you for your order.

What's the file content like?

The new version will be released pretty soon (next week) in our online store. You can also keep an eye on our blog.

Does you file has "FREEMATICS" as first line? If it does, please remove it.

You cannot adjust by 10RPM with current version of emulator. Only the new version (with software GUI) allows you to do this. The current physical knob controlled version is adjusted by about 100rpm. The range is 0-16000rpm. For ranges of all OBD-II PIDs, please refer to this.

It's ADK R3.
Arduino MEGA has enough power for processing 10Hz GPS input. However, if there are other time consuming tasks, it may depend.

The serial interface of the current emulator is only used to altering the protocol that the emulator uses. The commands can be found in the product description.

If you purchased the adapter recently, it is a V2 which is compatible with Arduino UNO. So you need to set the board type to Arduino UNO.
