Hi I have been using V3.1 on my XERUN 2.1 which works fine and is boostable.
It might be worth contacting CPD Racing to see if they can supply any of the pre V3.2 software. I have just tried their site but it only has links to hobbywings own site where they are no longer available, unless I am missing something. But worth seeing if they can help, always been really friendly and helpful in the past.
