Sorry, people were writing as I was. I think you have a valid point Sean and what we need to find out is EXACTLY what the black box is recording. I might not get anywhere but I shall endeavor to find out.
Someone connected with Porsche racing may be the easiest source of information. My guess is that they use the same black box for everybody. My tech confirms that 997 models and Boxster 986's will have 3 Zone values. (presumably the good, the bad, and the ugly)
