Thanks, again, Hubert.
Actually, I have been using the bmw controller with my CI v4b these last 2 years. And, last weekend, I spoke with the Carpe Iter guy at the UK’s Adventure Bike Rider show. He said it was better not to use the one marked “bmw control” but to use the ordinary Carpe Iter input option. As I have already stripped my CI fittings from my old bike, I haven’t been able to test that yet.
