Is there a way to run a “Virtual Dash”?

Because I do dash coding/creation at home without the racecar, I can’t validate things until I get to the shop or sometimes the racetrack.

Most things are fine, but I’d like to validate some Flagging system CANbus signals to ensure we are decoding and displaying them correctly.

We’re running 2 series and each uses a different Flagging system. We already have the Flagtronics system working, but a new series is using a MyLaps Racelink, that I’d like to try and get operational before getting to the track.

No, it is not possible. The whole logic, CAN data, etc. are processed on the device. There is no device simulator in ADU Client to do the device stuff once the device is offline. So to test things that have to be calculated, you need to have a connected ADU device.
