Nissan is using techno-wizardry in an effort to control the types of use and modifications made to their R35 GT-R – one would assume to enable Nissan to have some control when it comes to warranty claim time.

We’ve previously gone over the ‘smart’ GPS controlled speed-limiter that allows the mandatory Japanese 180kph limiter to be removed when the GT-R is on a number of ‘approved’ Japanese race tracks. Racetracks not approved can only be negotiated at a leisurely 180kph.

It now appears that this is not an automatic function but one that is changed via the menu’s on the GT-R’s touch screen, and yes, there is a catch. At the conclusion of your ‘unlimited speed’ blast around the track you will need to find a Nissan High Performance Centre, where you will surrender somewhere in the vicinity of AU$1,100 to have a safety check performed. If you don’t (and the car will dob you in), your warranty will be voided on your next visit to a dealer.

It is also rumoured that aftermarket alloys are a no-no as well, due to a sensor mounted on the valve stems of the factory wheels. Driving on wheels not fitted with the sensors, causes an error code to show on the dash. While, tuners such as Mines have fitted new exhaust systems to the R35 GT-R with some success, they report that any mucking about with the intake system causes major issues with the ECU.

Nissan have confirmed that the GPS system won’t be fitted to U.S. spec GT-R’s which means Australian spec GT-R’s will probably not receive the speed-limiting track nanny either. Expect the Japanese aftermarket tuners to find their way around the electronic fun stoppers eventually…they always do.
