Fury tuning port and lower serial port working at the same time problem


Recommended Posts

I have a Link Fury G4+ ECU and when I connect to the second external serial port while using the tuning port, to communicate to my laptop, I my laptop looses communication. the lower serial port is configured for OBD II. I have searched the help files trying to figure out why I can't use both ports at the same time.

The issue comes from the cable used.

If you are using the CAN dash cable it has the TX and RX serial wires also connected and this causes noise on the RS232 which is what the USB also uses.

You would be best to use a CANF connector to replace the CANdash and only wire the CAN wires.
