mm-hmm  
So,

1. connect the AlfaObd, select the speed sensor to be displayed.
2. I turn on the CAN H and the CAN L from the ObDIi to MCP2515(Arduino) module
3. turn the Arduino on and see the packages being request and response

Is it?

not. not really  
It should look in parallel, so we do not block communication with the computer, but simply observe.

I hope that you understand which assembly should precede the MCP 2515, as I did not indicate this in the diagram.  
study the materials on my blog.  
ps:  
need a translator))))

This is not announced yet, but in next release of RealDash you can use OBDLink adapters ([http://obdlink.com](http://obdlink.com)) as direct CAN adapters too, so if you are considering buying an CAN adapter, OBDLink MX Bluetooth would be an good option.
