Hello Guys,
I'll try to clear things up:
Hardware wise
* on the display only round connect the RX and GND lines only
* tuning laptop and v3 should have all three connected.
Usage
* when VT is talking to v3, it will disable aim steam, but it will be re-enabled on ecu power cycle (or optionally from VT on closing), display only round will not show data (or perhaps bogus) when VT is connected
* when VT is not used, aim stream data will be interpreted by the display only round, it does not send data.
Best regards, Dave
