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.

If you’ve ever had to splice into an ECU wiring harness to hook up some gadget or other you’ll know how heartbreaking it is to cut open the nice loom and hack it all to pieces. It’s pretty worrying for those that still hang on to some semblance of a warranty too because if Nissan happen to catch your handy work you might have some ‘splainin to do.

Wiring harness patches offer the perfect solution to this problem, they offer a passthrough matched set of plugs and sockets with a short length of wiring in between for all your patching adventures. Remove the harness extension and you’re back to stock!

This latest version, just released, now features coverage for all three sockets on the GT-Rs ECU giving you access to any signal that might pass it’s way.

You may or may not have heard of the RH9 Club before, and if you haven’t what sort of rock do you prefer to live under these days? Anyway, RH9 Club is a group of workshops throughout Japan who are capable of building a GT-R capable of 9 second quarter mile passes in street trim.

While no R35 GT-R has stepped up to this realm yet, the RH9 Club does not simply ignore them altogether. Recently, in order to bring their collective expertise to the R35 owners of Japan they got together in Kyoto to work together on a set of tuning data that could be applied to the GT-R and be made available throughout the member workshop network.

The results achieved are interesting. Over at Phoenix Power’s workshop a test car was donated by Decide 226 workshop as a test mule. Originally tuned by Decide, in standard trim, the car made 513ps with 68.6 kgm of torque up from a baseline of 459ps. Tweaked with the RH9 collaboratively built map, it went on to make 550ps and 72kgm of torque.

Later, the same map was applied to the Phoenix’s Power GT-R, which is modified with a Blitz SBC-iD boost controller and SARD high-flow exhaust and results were 614 ps and 96.1kgm or torque.

Just how much boost was being used in these runs was not revealed, wastegate modifications were also not detailed. In the past Phoenix’s Power’s GT-R has run around 19.2psi running down to 13 psi by redline to achieve the 616ps it has previously clocked.

Interesting results out of Japan for relatively stock cars. The price for the upgrades are set at 168,000 yen plus 10,000 yen installation fee for 2008 model cars. An extra 60,000 yen fee is levied for the 2009 JDM cars which require some TCM tweaks apparently. Installation is available at any RH9 Club workshop throughout Japan.

The Haltech team have lived up to their word and begun delivering USDM Nissan GT-R suitable Haltech Platinum Pro full ECUs this week. After launching not too long ago, some units are in the US already with more to come shortly. The ECUs ship with full OE grade harnesses, software, USB cable, and the connectors required to wire in the MAP sensors and wideband O2 sensor inputs.

All this for the retail price of $3,200 seems cheap!

This month marks the end of quite a long development process for the much anticipated Haltech fully programmable ECU for the Nissan R35 GT-R. The guys have released it now for Japanese and Australian delivered GT-R models with US delivered models to follow shortly.

High Performance Fuel and Ignition ECU for Nissan R35 GTR

The next generation in engine management. Purpose built for Nissan’s supercar, the Platinum Pro R35 GTR ECU is a fully programmable ECU interfacing directly with all the standard Nissan sensors and on board computer systems, taking control of all the essential engine management tasks such as fuel delivery, ignition timing, boost levels, camshaft positioning and correction maps.

The Platinum Pro R35 GTR ECU even interfaces with the factory Nissan CAN Bus for on board diagnostic and troubleshooting. The Platinum Pro R35 GTR ECU unlocks the limitless potential of Nissan’s VR Powerhouse.

Features:

• Sequential Fuel Control
• Direct Fire Ignition Control
• Variable Camshaft postion mapping
• Knock Detection
• Engine Rev Limiter
• Closed loop boost control
• Launch control
• Closed loop wideband 02 control
• On board data logging
• Speed density, Alpha-N or MAF tuning
• Additional user definable inputs and outputs
• Windows Software

In terms of those GT-R owners who have managed to extract big power with existing technologies (such as OE ECU re-flashes) you’ll be well aware of the protective nature of the stock ECU. Boost cuts, limp modes and so on all hold you back whether you’re on the drag strip, circuit or even occasionally just hard driving on the street. To utilise the GT-R’s VR38 to it’s full potential, this should be on your wish list.

For those of you chasing hard data and results, I point you in the direction of the recent NAGTROC thread where “One Lap of America” winner Underpressure has been tuning and testing with his Haltech unit already and has published some pretty amazing in-progress dyno charts.
