The program fired up I'll hook everything up this weekend and see if there are any issues. Thanks!
AArrgh. I have an OBDPros USB, and a GPS which does work. I could not get any input at all. Tried unplugging and replugging, turning car off, etc., and nothing. Tried input as both the default OBDPros, and the usbserial. Tried different inputs for the GPS, and no input. What am I doing wrong?
