Ok, offset might not be the correct word, i just don't know any better. Displacement, maybe? I am using N900 by the way, might that be the reason?

Anyway, now i had time to test a little, and the wrong speed display seems to be worse than in v0.0.2. Earlier it showed about the double of my actual speed, no it's more like 3-4 times. i was driving around in town, and it showed ~200 km/h for me.
