Looks like this is going to be a one man thread but for anyone who might get this problem in future I'll post that mine is now fixed and how it happened. I emailed Power Commander who replied promptly and suggested deleting the device and rebooting and reinstalling. I also uninstalled and reinstalled the PCIIIusb software. Upshot is it all works now and I've loaded a new map kindly sent by Sook

Thanks mate. Excellent service as usual.
I'm not sure if it is giving the bike more moomba. It goes like scalded cat but then it did with the stock map that came with the PCIII. A bit hard to test the difference on the morning commute. Certainly gets a few stares trying though
