Where did you buy your ECU from? All the info you need to set it up with your lappy should be on the cd you got with it in a step by step guide.

If not then here you go............

MS Setting should look like this, but your Port should match whatever COM Port your computer shows in the screen shot below in this case COM 6.



To get to this screen, right click My Computer, Properties, Device Manager..



In the above screen shot yours will not say USB Serial Port because that is my USB to Serial adapter and you are not using one, so it will just say COM # or Serial Port or somthing like that, should be pretty easy to spot as it wil probably be the only Serial device plugged into your PC!

You may also need to double click that and change the following setting to the same baud rate as MS which is 115200..
