Are you sure the Rx and Tx wire are connected to D1 and D0 correctly. Have you tried swapping them? Could you take a pic of the OBD adapter? I also want to make sure it is the correct model.

Here is the updated OBD library which forces to different protocols when automatic identifying is not working. Please try it and let me know if it works well before I will commit it to github.

Please use Arduino 1.5 if you encounter the low memory warning.

What car do you have? The corss at OBD means OBD can't be connected. Have you tried on any other cars?

Again, the stock firmware is built with the totally same code from what is comitted to the github.

Please upgrade the firmware of your emulator.

It should. Did you install the correct app?

Can you try upgrading with latest firmware which has just been released?

That's good suggestion! Will add that in next firmware update.

some PIDs can have negative value.
