OBDII Vehicle Speed Logging

Postby tadz0rz » Sat Nov 24, 2012 12:31 pm

Hey Guys

Just curious as to if the OBDII port shows actual vehicle speed compared to what is shown on the speedometer? Ie would the OBDII port give a reading which would be similar to tracking the vehciles speed via GPS?

Cheers guys
