They are both the same ECU (AEB) but loaded with different, label specific, firmware. So you'll need the software that matches the label to talk to them. The cable should be the same, the only difference being the earlier ones had an 8 pin Molex connector with only 4 pins used and the later ones had a 4 pin Supaseal connector. I suspect you've got the wrong version of the Romano software.
