Jombi Posted October 29, 2019 Report Share Posted October 29, 2019 I've read a bit about a Dragy device and a VBox, which appear to be high-precision GPS based devices. Due to the high cost of the Dragy and Vbox's, I've been using just an OBD2 adaptor with an app called CarScanner. I'm assuming it just hooks into the cars speedo and uses the phone's timer. So I guess the question is, how accurate would the car's speedo be, and when does the CarScanner pick up the first "move", ie, is it giving a 1ft roll or is it just detecting the first speedo non-zero input, and I guess same questions for the gps devices. Thanks, --jim Quote Link to comment Share on other sites More sharing options...
Nick Halstead Posted October 30, 2019 Report Share Posted October 30, 2019 Dragy is the industry standard for those who cannot make it to the track. The method your doing will give you a general idea. Dragy is a lot more credible. Think of it this way, OBD module= Hey the capitol of the USA is on the East Coast of the country. Dragy= Washington DC is located at latitude 38.8951111 and longitude -77.0363693, in the northern hemisphere. 1 Quote Link to comment Share on other sites More sharing options...
