So I have a USB to serial adapter from DIY. I installed the drivers, USB is on COM4 under device manager. I plug the serial cable in, open up megatune, click on the communications tab, and go to settings. Then I click test, and it says no response. There is power going to the MS, cause when I plug in the coils I can see the lights light up when I turn the key on. Everything is on Com4 at 9600 bps. Any clue what is going on here? Faulty serial cable? It was brand new from DIY when I bought my adapter. Could something inside the MS have come loose? WTF!

YES. Ignition is in ON position. With the coil wires disconnected, I should still be able to test the communications, right? My frustration level was jacked a few weeks ago with this F'n thing, but now that it's snowing, I have plenty of patience with it. I don't think I have ever seen anybody on this forum that didn't have a dozen problems with a MS, but once they got it straight, it was smooth sailing.
