Previously we reported on 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.

As we reported earlier, big Japanese manufacturers have also been tinkering with the ECU and companies such as Mines and Top Secret have been able to install custom wheels and engine mods without the ECU going haywire.
