**Hi,**

I’ve upgraded the firmware onto my emu black to v3 and the car runs. But I need configure the cuts and blip strategy. Currently I’m using an external controller to send CAN signal for cuts and blip via can switch board. How do I get the CAN analog in from the external controller configured for cuts and blips on v3?

Thanks
