Hi Finn
I have a backup CAS that I was using with my EC2 way back and at one point it was working.
Its mounted 90 degrees anticlockwise from the standard Renesis CAS (looking at the CAS end of the engine)
Its not being used with the latest Closed Loop (autoprogram) code I have in my EC2 at present.
I can’t recall if thats because the BUSENSOR flag wasn’t set or internal code issues.
