GT-RR partners with John Shafer
Monday 28th September 2009

It is with great pleasure that we announce GT-RR’s newest member of our team of GT-R specialists. John Shafer has recently joined GT-RR officially as our Master GT-R Tuner. John will assist our projects and clients all over the world with technical support and custom tuning. GT-RR has already had a successful history working with John on various projects and we are excited to have him as an integrated part of our team to even better serve our clients needs.

John as many of you may know was the R35 GT-R tuning guru behind the development of the Cobb AccessPORT for the GT-R. John was also the first aftermarket tuner in the world to collaborate on the reverse engineering team for the GT-R’s ECU during his time working for Cobb. Since then John continued to make advancements to the Cobb unit, personally writing every map for every AccessPORT around the world. John has also served as a liaison for nearly every GT-R specialty tuning shop in North America. Amongst all of this, John has also written a tuning guide for Cobb which teaches their dealers how to tune the R35.

We at GT-RR are proud to take our level of service to new heights by adding John whom many would consider to be the most respected and experienced R35 GT-R tuner in the world.

Additionally, as you may have heard, we are now offering complete car building services on both coasts of the US as well as remote computer tuning worldwide. John’s tuning facility, Akuma Motorsports of Morganville, New Jersey has become our official east coast partner for our client projects. If you need any work done on your car, regardless of where you live, we now offer more flexible and cost effective solutions than ever before.

Keep tuned to our website and blog as we release more information of our new 2010 Black on Black Street car project and the finishing power modifications of our Toyo GT-R project, both of which are being tuned by John out of our east coast partner facility.

Client support and technical questions for John can be emailed to john@gt-rr.com

The guys over on NAGTROC have a pretty interesting discussion going regarding custom tuning of the staple GT-R ECU upgrade, the Cobb AccessPORT. The guys have figured out how to write maps that control boost pressure based on RPM.

While this doesn’t sound like much when described like that (and there’s probably more to it), its actually quite a big deal. What it allows the average GT-R owner to do is to get more tuning value from their Cobb AccessPORT before resorting to electronic boost controllers and aftermarket wastegate actuators to keep the GT-Rs small turbos from boost spiking, especially on gear change.

The guys at GTC Racing have used the latest code and maps on their GTR to run 10.8 @ 125.92 mph at Santa Pod drag strip in the UK. This car is fitted with neither a boost controller or a set of actuators. It’s also running street tires but is fitted with a full turbo back exhaust and Forge Motorsports upgraded intercooler.

COBB Tuning really need no introduction for people in the GT-R world as their AccessPort product is the backbone for something like 99% of the world’s tuned Nissan R35 GT-Rs.

Today they’ve extended the range of top quality parts with the addition of a limited edition secondary engine oil cooler kit. Keeping engine oil temps in check is essential for anyone planning on even moderate amounts of circuit work, especially in warmer climates.

The core of this oil cooler kit is the Mocal 25 row air-to-oil cooler fixed in place by a custom CAD designed powder coated bracket. The bracket allows the core to be lined up to take advantage of the unused drivers side intake through which air is guided using genuine Nissan OEM ducting (included in the kit).

For the rest of the kit, nothing has been spared with attention to detail evident in every component. From the high quality anodized aluminum hose fittings to the genuine OEM replacement gaskets included.

Expect these to sell out fast but right now you can secure yours at one of the links below for just $1,395.

Suffer no more Euro GT-R owners, the Cobb AccessPORT is now available for your Nissan GT-R! Thanks to the hard work and forsight by GTC-Racing based in the UK, who spent hours road and dyno testing, the AccessPORT can now be yours and features, as expected, two stages of power upgrades just as the overseas models do.

The net performance gain for each AP stage is:

Stage 1, 97 RON Fuel:

• +63 hp and +70 lbft of torque

Stage 2, 97 RON Fuel:

• +70 hp and +90 lbft of torque

So the Euro spec Cobb AccessPORT features not just those two maps but also the following purpose built maps:

• Anti Theft (security mode, car will not start)
• Valet Mode (reduces rev limit and power level, so car cannot be driven aggressively by others)
• Stock Style (normal tune with only speed limiter removed)
• Economy (maximum fuel economy mode, sacrificing performance for better fuel economy)

There are also tonnes of other extremely useful functions like:

• Re-flashes ECU through factory Data Port (OBD)
• Ability to uninstall and revert back to original (stock) ECU data
• Ability to store multiple maps on unit, allows switching between maps at user’s convenience
• Ability to read DTCs (trouble codes) from the ECU, BCM, Multi-AV, IPDM, Pre-crash Seat Belt, Meter/M&A, and Adaptive HL computers
• Ability to clear DTCs (trouble codes) from all vehicle computers including infamous “Bonnet Light”
• Ability to update reflash maps as improvements become available
• Firmware is Internet updatable (new features may be added as they become available)

All up the Cobb AccessPORT is a bargain at £750 + VAT and is available immediately through our friends at GTC-R / GTR23.com who can be contacted through their website linked below.

Good friends of ours at GTC are assisting the testing phase for the European spec Nissan GT-R Cobb AccessPORT as of right now. Their brand new Euro GT-R has the prototype maps installed and is undergoing road and dyno testing this week. We’ve been told to expect it any moment for delivery into the eagerly awaiting hands of the European GT-R owners.

Good news for those who feel the GT-R could be just that smidge better … or even those who feel it could do with a whole lot more actually …

While you’re here you may as well check out some pics of the GTC-R development car below, nice stickers!
