COBB Tuning Release AccessTUNER Race for Nissan GT-R
COBB’s famous AccessTUNER Pro software for the Nissan GT-R COBB AccessPORT has traditionally only been available to approved AccessTUNER workshops. This is fine for the majority of end users but for race teams or for experienced tuners, returning back to base for a touch up has been restrictive.
AccessTUNER Race end-user tuning software comes to the rescue here offering the ability to do everything from modifying existing maps to touch them up to building completely new maps from the ground up for a major retune.
AccessTUNER provides control of vital engine parameters to the user, such as; intake cam advance, wastegate duty cycle, fuel injector scalar, boost control tables, knock sensitivity, rev limiters, speed limiters and many more. Customizable data monitors let the user choose which channels are monitored to see how changes impact the behavior of the engine. The built-in data logging capability captures data from up to 30 channels across the entire rev-range, allowing detailed data analysis after a dynamometer test. 3-D graphical mapping gives the user a comprehensive view of engine behavior across three axis to evaluate where performance can be maximized. An integral dashboard shows the user-chosen gauges to be displayed during the tuning process.
It seems pretty full featured, in fact it looks almost exactly like the Pro version except that it is locked to a single AccessPORT. So no tuning your friends GT-Rs with the Race version unfortunately.
Still it’s great value all the same, on top of the already giant bang for your buck AccessPORT. It sells for $695.

GTC 750R Demo Car Shows Off GTC’s New Parts Lineup
UK based tuner GTC Racing has been making a great name for itself with GT-R tuning and original parts since launch and the latest iteration of the combined knowledge and hardware is the GTC750R GT-R. The team have put it through it’s paces on the dyno and on the track. The result is a GT-R that is hypercar quick with looks to match.
The car features a lengthy list of modifications with some of the highlights being:
- GTC 90mm Titan Exhaust with GTC Titan 90mm Y-Pipe
- GTC 80 mm Zircotech coated de-cat front pipes
- Hybid IHI/Garret GT30 ball bearing turbos
- Garret Wastegate Actuators
- 1000cc ID Injectors
- GTC 80mm MAF pipes (prototypes) – w/ HPX MAF sensors
- Twin 255 lt fuel pumps w/ upgraded fuel lines
- GTC Marston Core Intercooler w/80mm hard pipe kit (no BOVs)
- GTC Radiator
- GTC 14 plate clutch system & steel plates & shims
- Prototype gearbox cooler (water type)
- Alloy extended gearbox oil pan
- Alloy engine sump
- COBB Tuning AccessPORT w/GTC custom tune
With those mods, and a good driver, it reeled off a 10.3 @ 139 mph during it’s shake down testing. The guys report that they have cracked the GT-R’s infamous launch control systems and can now raise the ECM’s launch rev limit to wherever is most optimal. Given that, we expect to see an interesting few runs coming up soon both from GTC and from abroad.
For more information on the latest range of GTC products for the GT-R, head over to the GTC-R website, give them a call or check out their discussion thread over on the NAGTROC forums.

Nissan GT-R Quarter Mile Record Falls Again
It’s been a while now but the previous quarter mile record (at an officially sanctioned drag strip that is) of 10.31 @ 131mph was destined to fall and fall it has! The GT-R nudges its way ever closer to the 9 second mark thanks to SSP, who built the car, and Jack Cecil from HP Logic who tuned it, by running a 10.236 @ 136.02 mph in Florida this week. A video of the pass is below.
On the same night the guys also recorded a 10.52 pass at 141.15mph in their white GT-R.
Certainly getting quicker and quicker, will we see 9 seconds sooner rather than later?

HP Logic E85 and Cobb AccessPort Powered 10 Second Drag GT-R
Cobb AccessPORT ProTuners, HP Logic have been have been experimenting with E85 fuels on behalf of a customer with some great results lately. With some modifications to this GT-R’s fuel system the car ran an amazing 10.48 ET @ 133.21 mph at the drag strip.
Other than the fuel and exhaust system, the car was stock standard down to the turbos, actuators, wheels and even the heavy runflat tires.
With the E85 tune, this GT-R makes 573whp and 577ft-lb of torque as measured on a Mustang Dyno but of course, it does chew through the fuel to get there. It needs 950cc injectors and dual Walbro fuel pumps to supply enough of the go juice to make this power. The benefits are plenty though including great power and cooler burning which actually helps keep overall engine temps down.
The owner is running the car with it’s E85 tune and fuel again in the next few days and has now upgraded his wheels and tires so should be interesting to see how car he can push the combination of standard turbos and E85. Follow his progress in the NAGTROC thread below…

COBB Tuning AccessPORT Powering the GOTO:Racing Time Attack GT-R
Earlier this month, the Cobb Tuning team put together this rundown of the features of the Cobb AccessPORT ECU reflashing tool for the Nissan GT-R. They’ve chosen to focus on how the top level time attack team, GOTO:Racing use it on their ~800hp GT-R to get the best results out of the GT-R with minimal level of fuss.
The Cobb AccessPORT still stands as one of the best bang for your buck modifications anyone can do to their GT-R and this video highlights a couple of the features you may not of known it had.
On the topic of the AccessPORT for the GT-R, Cobb Tuning have also now released a version for the East Asian and Japanese markets. Preloaded with the latest 2.0 version of the Cobb Tuning default maps, it’s available now. This brings the total global markets supported by the AccessPORT up to:
- Australia
- East Asia
- Europe
- Gulf
- Japan
- South Africa
- United States
Cobb don’t stop there though, one final AccessPORT related announcement was made recently, regarding the AccessTUNER Pro software compatible with the Nissan GT-R. The latest release of the software, version 1.8.1.2, contains updates that will allow tuners to utilise the Proportional Gain Boost Control logic, as seen in the canned 2.0 maps. It’s also available now and supports all of the above listed regions.

COBB Tuning Launch AccessPORT v2.0 Maps for Nissan GT-R
Merry Christmas to all and I hope you’ve all had a great weekend with the family pigging out on tonnes of food and getting stuck into your gifts and gift giving with loved ones.
Cobb Tuning are in the giving mood this festive season as well as they’ve completed the finishing touches on a set of brand spanking new canned tunes for Nissan GT-R AccessPORT owners.
You may have heard by now of the latest breakthrough innovation in tuning the GT-R. A method known as proportional gain boost control which allows more elegant control of the GT-R’s boost. This helps especially at the top end where boost spikes and wastegate creep were turning into big big problems indeed. With these problems resolved, the Cobb AccessPORT has gone on to power some monster GT-Rs with one over 785awhp.
While 787hp may not be everyone’s goal, over the past week we have also seen a “AccessPORT tune only” but otherwise completely standard GT-R break the 10 second barrier (10.953@126.79) at the drag strip. Quite a nice result with the new way of mapping boost control.
These new maps are available for download now from the Cobb Tuning website for all AccessPORT owners. This includes globally delivered models such as the JDM, Australian, East Asian, USDM, and South African GT-Rs! Maps are also broken down into fuel type so you can pick the most appropriate to flash based on available fuel in your area.

GTC GT-R Runs 10.8 @ 126mph with Latest AccessPort Tweaks
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 Release Secondary Oil Cooler for Nissan GT-R
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.

Cobb AccessPORT for Euro Spec Nissan GT-R Now Available
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.
