Cobb Tuning has re-engineered its AccessPort control unit for the new R35 Nissan GT-R. For those of you lucky enough to own a GT-R and not content with its performance out of the box, the $995 AccessPort will reflash the ECU to any one of six different tuning levels. There are three levels each for Stage 1 and Stage 2. Stage 1 can get you up to 63 additional ponies and 70 lb.-ft. of additional twist, while Stage 2 can boost the numbers by 70 and 90 respectively. The AccessPort can also save your stock ECU data and reflash it when you decide you're finished with all that extra gumption. According to a GT-R owner who tried it out, you can be blowing past all those regular GT-Rs in less than an hour. And that's not all: you can store multiple engine mapping programs, remove trouble codes, install reduced-power valet and economy modes, and update maps over the Internet. It seems like a ridiculously easy proposition for making your supercar that much more super. So if you got one of those GT-Rs that are a little low on horses, this could be just the ticket.





With all the news surrounding the Nissan GT-R V-Spec, the progress on the Godzilla tuning front has been largely overlooked. According to a recent article in Japan's BestCar magazine, the Amuse team has broken the 600 hp mark (at the crank) with a combination of a high-flow exhaust and a tweaked ECU. There were no details on how the GT-R's computer was hacked, but Amuse was able to up the boost to 18 psi, resulting in an increase in output to 602.73 hp and 576.95 lb.-ft. of torque.
However, tuners are beginning to question how the stock gearbox will hold up under the strain of additional output. MCR, which brought out its GT-R for filming of Hot Version 93, has been exacting its own brand of punishment on its tuned GT-R and is worried how long the transmission will last. It's not clear if the tranny woes are due to the clutch plates or something else, but it's been all but confirmed that dual-clutch gearboxes have an issue with additional torque since the friction surface is much smaller than on a stock (read: single plate) clutch. MCR's best guesstimate is that the stock 'box might only be able to hold up to the additional power for 12 months before problems begin arise. Now, we're particularly interested in how Nissan is beefing up the tranny on the V-Spec to handle its rumored 600 hp.
