There is no point if you can't get it connected and working at home. Windows 7 might call for a different driver installation. But it really should be as simple as, install driver, plug ECU in, ECU gets installed by Windows. With ECU plugged in start up TunerPro and it should recognize it, if it doesn't then you need to select the correct port in Options.
Also it looks like the ECU likes to be on lower ports, like 0-9 instead of 10+ port numbers.
