Nissan GT-R recognizes tracks via GPS and removes speed limiter
We know that the Nissan GT-R's ECU wizardry is impressive, but this little tidbit left us in awe. According to our friends over at the GTChannel, the GT-R's integrated computer limits the vehicle's speed in Japan to 111 mph (180 km/h), but once the GPS system detects that you've arrived at a domestic circuit, it removes the top speed limiter for all-out track assaults. In the U.S., they've bumped up the electronically-limited top speed to 156 mph (250 km/h), but there's no integration with the GPS here in the States, meaning that anyone that wants to go faster on track has to have the ECU modifed. Nissan has made several overtures that the GT-R's ECU will be a tough nut to crack, but we're sure that enterprising tuners both here and abroad will be able to coax a few extra ponies out of the twin-turbo'd 3.8-liter mill and remove any electronic nannies that go with it.

RE: Nissan GT-R recognizes tracks via GPS and removes speed limiter
I had a nissan titan since they first came out, and the ECU was rediculous. there were over a dozen aftermarker tuners that tried to crack it, with NO luck. to boot, each model year had 2 revisions to the ECU that made each one UNIQUE to write to. one firm that does programming (The only one to my knowledge) can only control timing, and injector pulse width, and even then if the ECU loses power, it factory resets....
If nissan does that the the GT-R, which it sounds like a similar complexity, they're straight ignorant for eliminating the aftermarket tuning options... granted there's more a tuning market for GT-Rs over Titans.
