Shunt needed with OI board?

Guys,
I'm panning using a custom digital dash board to display info such as speed, temperature and all that kind of things....can I get all that data from the OI inverter board or do I need a shunt resistor?

Hm... OI can output CAN data stream. But i dont know if you can directly use the DC current data. Maybe not really accurate...
Speed and temp info is there and can be slaved to CAN.

The DC current figure is as accurate as the current sensors are calibrated, That said it doesn't include miscellaneous currents like DC/DC, heater etc. Better source current from the BMS (or a shunt)

Any particular shunt that you will recommend for a dual motor set up?
