Using a Qstar BT-Q818XT external Bluetooth GPS receiver at 10Hz. Says I run 11s plus 0-100kmh hahaha ridiculous. With a stop watch I'm getting around 6 to 6.2s the app is not very accurate. My 60ft in the app is 6.4s @ 42Kph haha my car should be doing anywhere from 2-2.5s on the street 60ft. Not sure what's happening here but please fix it.
