OK, so I bought the Durametric scanner and am pleased with it. In the included software version 5.x there was nothing about the On Board Computer. I downloaded the beta version 6.x and it allows enable/disable to the On Board Computer amongst a ton of other features but it is a beta version. My Boxster is a 1998 and did not come equipped with OBC active and control stalk. I have been instructed by tech at Durametric that scanner transmits the same command to activate as dealer tool. Just wondering if somebody else has activated at least their external temp display with this scanner. Wanted someone to tell me there's water down there before I dive in this pool, Thanks!
