I just got mine a few days ago, unfortunately too late, i used an ELM dongle and torque, and then guessed at the error codes (Bad idea) though educated guess at chain tensioner, turns out no reading at all from bank 2 cam sensor, still trying for a solution to the problem, but I would have saved 120 bucks and two evenings and a good part of the weekend to discover it still wont run right (worth every bit of the $289). Durametric is the first thing I think people should look at, then buy the used Porsche.... If you cant afford the tool, best not drive the car....
