How much does the SM-PCE1 cost? I have an old windows machine around here somewhere I could probably get to work. Funny, this is the first time I've actually needed a pc in two years, ever since I got my iPad Pro. Anyway, with the SM-PCE1 software can I change things like shift speed, multiple gears shifted, etc?

I'll probably wait until I need a new battery. By then maybe the cost of the modules I have will be obsolete and cheaper.
