Motor Trend's Scott Kanemura sat down with Michizio Niikura, the president of MINE'S Motor Sports, the first aftermarket firm to get its hands on the new Nissan GT-R. The conversation centered on the roadblocks Nissan has put in place to stymie high speeds and limit modifications to the GT-R.

We've previously reported on how the GPS system fitted to the GT-R would remove the 111 mph (180 kph) speed limiter when the car arrives at a track, but according to Niikura, it will only work on pre-approved racetracks. However, the GPS sensor doesn't automatically remove the limiter by itself, it has to be manually changed by navigating through a series of menus on the GT-R's touch screen. While having to go to a Nissan-approved track is daft in its own right, it's even worse when you leave. After the track day, owners are required to head on over to a Nissan High Performance Center where a $1000 safety check is performed. Don't do it and the factory warranty is void.

Another rumor that began circulating after the Tokyo Auto Salon has also been confirmed: aftermarket wheels are out. Supposedly, all the GT-Rs on display at TAS had to be driven in on the stock rollers, jacked up and then fitted with the tuner's chosen wheels. Due to a sensor mounted on the valve stem, if the GT-R is driven with aftermarket rims, an error code is thrown on the dash. And although MINE'S has fitted a custom exhaust to their shop car, they've found that any modification to the intake system causes the ECU to go haywire.

While all these findings are disturbing draconian, GT-R owners here in the U.S. won't have to worry about the speed limiter/track day issue. Nissan has said that the GPS system won't be implemented here in the States, but the future of tuning the GT-R remains questionable. Top tip Zac!

 

go computers...

 

Nissan GT-r the perfect Nanny mobile.

 

Dont you think the aftermarket will come up with something to get past the ecu throwing codes for new wheels, exhaust etc?

 

the thing about aftermarket wheels--
even the 350z has a TMPS in the stock wheels. Aftermarket wheels will cause the tire pressure light-warning thingy on the dash to light up because the system doesn't pick up the signal from the TMPS (because it is no longer there)... no biggie?

standalone/piggyback EMS = <3

 

TPMS.

 

Not a big deal, all the top Jap tuners will have it sorted in no time.

 

tire..pressure... crap. that's tp.

na babo.....T__T (no korean at school computers)

 

+1 ... I have no doubt it's only a matter of time. If some 14 y/o punk can get into the FBI mainframe, I can't see why a bunch of people couldn't get into a car's ECU! Let's see who's first to offer a standalone engine controller.

 

I should ask my friend Akira who is one of the tuners for Top Secret.
