The JDM (Japan Domestic Market) version of the Nissan GT-R has a speed limiter set to 180KM (111mph). This limiter automatically disengages whenever the car is on a racing circuit. This feature is managed through a communication between the car’s GPS and the ECU. Now how cool is that?
There have been reports that the GT-R US version will also possess the limiter but to a higher speed of 250KM (156mph). The downside is there is no communication between the GPS and the ECU. This will become such a drag for those aiming to go really fast with their GT-R.
Cracking the ECU to cut the limiter seems the only way to make the US GT-R faster. But Nissan said that only a handful of people in this world can crack the ECU of the GT-R. As for the Japanese models, maybe hacking the GPS and making the ECU think that it’s in a racing track might work. I guess it’s up to the aftermarket car modifiers to figure out how to unleash the full potential of the GT-R.
