How did you arrive at the crank-figures? Is it calculated by the app?
I just received an OBD2-adapter myself, but I haven't tested out HP yet. I'm a bit skeptical to the measured speed, as it is usually pretty much identical to what it says on the speedo. It should be a fair bit lower...
The only test I've done so far, is acceleration from 80 to 120 km/h. A manual 120d in 4th should do this in 5,7 seconds. I have an auto 120d with 'power reduction' (120 kw as opposed to 135 kw), and I did it with kickdown in 5,9s with a full tank of fuel and a passenger. If the figure is correct, then I'm more than happy.
