You will need either a usb to serial adapter or a straight though serial cable.
Tunerstudio can probably autodetect what version firmware you have on it and import the tune that way you can datalog and see whats going on.

If you don't show us a log, MSQ, and provide more details, we can't help you help yourself.

You might want to include SOME information about your car other than 90 and "megasquirt i believe"
