Upon reinstalling the software, we now have communication again, albeit, 4 out of 5 times tried. We wiggled the USB cable from the laptop all the way down to the QuikData, and got it to communicate. We had a driveshaft vibration last year that was very violent above 4,000 RPM, and dad could hardly hold the shifter. We might have a connection issue in the wiring cause by that vibration. It does sound like, however, that we should take DK's advice and get the recommended adapter from MSD. That might correct the problem.
