Nissan GT-R ECU cracked and delimited !! Previously reported was the Nissan GT-R’s ‘uncrackable’ speed limiter, which could only be delimited when entering circuits via a GPS link. While Nissan assured customers the encryption on the ECU was very sophisticated and difficult to crack, U.S.-based COBB tuning has indeed cracked the speed limiter and is now working on sorts of other modifications including the fuel-mapping and boost pressure controls.
Currently the GT-R is limited to 180km/h (112mph) unless the car detects you’re at a race track, but COBB tuning reports that they have removed it and are currently undertaking in-house testing. COBB’s GT-R is a Japanese-domestic-market model, but the company predicts that by the time North American spec cars arrive they will be well prepared and practiced in the art of tuning the GT-R’s ECU. Without the speed limit, the GT-R can hit a claimed 193mph.
COBB also has a number of modified ECUs for Nissan’s 350Z and Infiniti’s G37. Other modifications the tuner has in store for the new Nissan lineup include high-flow intake and exhaust systems, suspension and handling mods, electronic boost controllers and carbon-fiber accessories.

I couldn't image in the US that some tuner here wasn't going to have that ECU cracked before to long. I mean come on they push all this press out how this car is a 997TT killer and the limit the top end to 112mph, heck I think Prius will go faster then that

Yes Drew, that it is. This is how you crack the ECU. Basically you go to the fuel consumption screen, press E, tap the brake 3 times while holding the horn and boom, no speed limiter.
I've also read from a confirmed Nissan source that the speed limiter and GPS tracker does not apply to the US models. The JDM ones are limited.

As far as I know Mines and Amuse already cracked it a couple weeks ago. I'm confused as to why Cobb is worrying about it if US models won't have a limiter.
