I wasn't going to post again on the delay of the config tool, but the lack of any feedback on progress is not good. The AGA MkII seems to be a good design, but that is all I can say at the moment. I don't want to send it back for a refund, I want to use it. As this is the only source of new kit for an ageing machine what choices do we have? Return it or lump it I guess. I hope the tool is ready soon.
After this experience I would not order any kit without completed software, I will wait for everything to be complete before purchase.
