I have a Durametric, but it's old and for my 99 C4 and I rarely boot my mac into Windows so it's a big hassle to use that Durametric, but I will update and try and probably get a new Durametric unit.
I don't think the older version will work with the 997. However I thought I read on the Durametric website that Durametric might upgrade your older cable for free or a reduced cost. Worth a call.
