I know its a bit late, but I've got a second hand Wolf 3d V4 & a hand controller that needs a good home, took it out of my z to get registered plus a mechanic at some point erased all the data for my rb20det and i hadn't had any luck getting it tuned right (didn't want to spent he money to get it set up by a wolf specialist)
At the moment its sitting on my floor, at some point when i can be bothered i'll send it to wolfems to get tested, costs around $90.00, then i'll try to sell it on here or on ebay, I'd be looking for ~$500.00 including the manual on cd with the software. I'm open to negotiation.
Yeah so the offer is there for anyone to take it right now, I'll even express post it to you for free. otherwise wait around till i get a chance to post it with photos etc.
