AFC map uploading question (tuning newbie)

seems like I am even having problem connecting the computer with the AFC.

I am using this kind of "serial to USB" adapter since my laptop does not have a serial port. (see in picture)

Would it not work???

We have not personally used the usb connectors, but it sounds more like a software error than a connection problem. If you open up the r4 software and go to download map from ecu do you get the error message?

The buttons at the top left corner of the fuel map do not even become active.

When I tried to connect the computer to the ECU. It would attempt to do it (when the red bar pops out and count down from 10). But it never did connect.
 
Hum, if it's a cable malfunction check the following: drivers, com port you're using and then the cable itself (could be defective).
 
1st: is you have drivers for you cable install them.
2nd: try changing the port # until you hit the end of the list (of ports).

3rd: get a new cable if 1 & 2 didn't do the trick.

so meaning with the correct cable and hitting the right port # should pair up the connection right on?

Yup, I experienced about the same problems at school (computer engineering) when we weren't using the right port #... the difference was that we only got an error message instead of the whole program crashing (but that's relative to the way the program was coded...). So if you have the right drivers installed and that you have the good port, I don't see any reason why it shouldn't connect... except if your AFC is damaged/defective but it would be surprising.
 
hmm if the afc is damaged it should spit out a fragmented code...just a silly question by your car is on the "ON" position when you try to connect right? THe afc has to have power on in order to connect to the r4 software.

Yes I can confirm that.
