AccelTest measures while driving (e.g using the Drag 1000 track):
0-100 Km/h, 0-200 Km/h, 80-120 Km/h, 100-200 Km/h, 100-0 Km/h (in meters), quarter mile (402m) and 1000m. It shows the last and best values for the car.
Just unpack it in ...\apps\python\, enable Acceltest in the general settings and enable it in when driving like any other app.
