JamieP Posted December 15, 2011 Author Share Posted December 15, 2011 I did see that but didn't think it was a GPS one? Quote Link to comment Share on other sites More sharing options...
johnny g Posted December 15, 2011 Share Posted December 15, 2011 I think it uses the accelerometer in the phone - more accurate IIRC. Quote Link to comment Share on other sites More sharing options...
Notts_TT Posted December 15, 2011 Share Posted December 15, 2011 Just bought dynolicious, I can sit on my sofa, tilt phone back and do a 3 sec 0-60 and a 9 second quarter at 199 mph ..... Not sure if it's gonna be accurate, off out in my cooper s now, will let u know... Quote Link to comment Share on other sites More sharing options...

I thought them type was just a guess? and can be fudged if you put in a different weight of the car. Quote Link to comment Share on other sites More sharing options...

To be honest, they're not going to be too accurate no matter what. Quote Link to comment Share on other sites More sharing options...
