all i wanted a carpc for is to get some diagnostics.
so i went and bought an interface (

and bought pcmscan.
so i went and ran everything and it says it is connected but won't pull any diagnostics! i spent a lot of money on it i would really appreciate it if someone could help me out. the car is a 1998 ford mustang.
also, the problem isn't pcmscan. i also tried one of the free programs that came with my interface and i had the same issue. it says it connects, but doesn't actually read any information!
