Realdash support for Adaptronic

Hi does RD currently support any adaptronic ecu via USB? I have an adaptronic e420d but I don’t see this ecu selection in the list.

No. Only way to connect to Adaptronic ECU is to use CAN adapter.

What can analyzer would you recommend best to be used for adaptronic and real dash use?

Any of the supported adapters should work just fine:

RealDash | Manuals | Supported CAN/LIN Adapters

USB adapters generally connect a bit faster than wireless ones, but there is no big difference on frame throughput per second. Although, you may need USB for charging, so then a Bluetooth adapter is a good choise.
