It would be more accurate to call it upgraded. I've gotten mixed answers, some say it's a software change in the ABS ECU while others have told me the ABS ECU is replaced with one that has the GT4 coding.
Perhaps it can 'technically' be coded, but it cannot be done remotely from everyone I've talked to - hence why it's such a PITA and why almost no one has done it. Everyone I've spoken to either sends you a new ABS unit with the GT4 ABS included or you send them your current ABS module (including the ECU) and they 'upgrade' it (whether that's replacing or coding) the GT4 ABS map onto it. It's quite a bit cheaper then going to a full motorsports system but I'm not sure how the two would differ in performance.
