Indeed, however why not give it a shot? It'd be interesting to see how it performed when tested back to back with a gtech. I got the full version on my N95 and with only a couple of attempts got a 3.9 0-60km/h... yes only 60 km/h cause i was just heading home from footy and decided to give it a go. Tried only once in the missus vs auto with buggered zorst and got a 4.1. Did a few times in my van (1.4l holden combo lol) and got a 5.2. Has decent breakdown of the runs, this was in my commo: 18/06/2008 21:23 0-60 km/h: 3.9 s 0-10 km/h: 0.4 s 0-20 km/h: 0.8 s 0-30 km/h: 1.3 s 0-40 km/h: 2.0 s 0-50 km/h: 3.0 s 0-60 km/h: 3.9 s 0-10 km/h: 1 m 0-20 km/h: 5 m 0-30 km/h: 9 m 0-40 km/h: 18 m 0-50 km/h: 32 m 0-60 km/h: 47 m Peak: 66 km/h 0-40 mph: 4.3 s Got no idea if thats any good or not, and havent graphed the results yet to check how smooth the acceleration line is (would help determine GPS consistency) Only suggestions would be to make use of the accelerometer particularly for starting timing and perhaps measuring G-forces at launch, and graphing the results on the phone would be nice. Either way, cool technology for use on a mobile phone!
