Re: PROJECT: Hacking Fiat Grande Punto CAN BUS with Arduino and AlfaOBD

Hello,
can I ask you for help.
I have Punto EVO. I read data from OBD with arduino and print it on LCD (16x2). Could you please tell me how to print it on dashboard display?
Which header/PID to use?

Hello R0bert,
I'm still investigating about it, I don't have much time since I started to work on a new company, but the latest thing I made was spoof info to the speedometer and rev counter, but as far as I know nowadays, I don't know how to spoof info into the dashboard LCD. I wish be able to do it, but it takes time.

I bought two CAN-BUS modules for arduino and an ELM327 just for spoofing and read and send data in a fake CAN-BUS line I made on my room, I have two Blue&Me modules, my old dashboard, and my old car radio (now I have a new one with Android), so I want to connect all of them and hack their protocol. My problem now is what baudrate on a "Grande Punto Low Speed CAN" is being used, I think that is 50kbps but I am not sure, I tryed all kind of baudrate speeds that are used usually but they only effect I finally get is that CAN-BUS conections is interrupted and no longer works until I remove the Arduino with CAN-BUS module.

I sniffed how MES send data to dashboard to check the display, and the only thing "new" is that I can change the pattern of dots ON and OFF

Best regards,
Julio.

Hi Guys...
have you been able to identify baudrate on Low Speed Can-Bus (CAN-A/CAN-B) in grande punto?
I have the same issue. I have my old instrument cluster + my Arduino board with CanShiled but I can't sniff any data out of the instrument cluster :/
