I have read a lot on megasquirt, but I can’t find out how to get it to communicate with the laptop I am using an usb/db9 programming wire I know works because it worked on the 420a it was originally on. Can some one please help me to get this thing to communicate I know you have to fine witch com port. In my case it is com port 5 but when I go to test it, it does not see the msns but sees the programming wire. I have not started the car yet just trying to get the msns up and on line. The msns is coming on no doubt about that the two l.e.ds flash when I turn the key. The mega tuner will come up on my computer but, like I said when I test the com port it told me nothing is connected. I am really new to this stuff and I really need help? Thank you
