67 twin turbo dart

Well got it all done and went to test and the laptop still wouldn't communicate with the MS3X, even tried searching for the com and nothing, new cable and all. So its off to DIY to have them check it all out not sure if something happened inside or what. So everything is on hold till I get it back. Will update when I hear from them.

ive always had issues with connection to tuner studio with my laptop using ms2 3.57. I usually unplug the usb and plug back in but it’s always doing it. Irritating. I thought it was my crap laptop and I had one usb cord go bad too. Interested in what DIY says. Yours sounds worse, like it won’t even connect once.
