One of the many safety features on the very fast Nissan GT-R is a speed limiter that would only switch off when a GPS link messaged back to the home office saying that the car was within the safe bounds of a race track. On normal roads the sophisticatedly encrypted ECU would only allow GT-R owners to play at speeds up to 112 mph.

All that is said to be changing however, as U.S.-based company COBB Tuning has said that it has cracked the ECU, and is in the process of in-house testing. Along with allowing the untethered GT-R to reach its fully mad top-end of 193 mph (claimed), cracking the Nissan computer should also allow COBB to tinker with fuel-mapping and boost pressure controls.

COBB has also been busy working with Nissan’s 350Z and Infiniti G37; the company plans to have aftermarket exhaust systems, suspension mods, and more electronic trickery available soon for those cars as well.
