DeltaABS (US office) got back to me. They don't have a CAN bus log and their race car is an hour away.
I've explained to them that I'm fine waiting days, weeks or even a few months for them to get a CAN log and send it to me. I also sent an email to the UK office. (scs-delta.co.uk)
Once I have that log, I can verify (and demonstrate on video) a working speedometer and warnings lights on the gauge cluster.
The module can be developed using their documentation (DBC file), so I don't need it, but sure would like it to verify it on my test bench where it is easy to update code for any bug fixes or feature updates.
Future updates will be in this thread:
Ice mode solution?
