AMS Release Upgraded Mass Airflow (MAF) Sensors for Nissan GT-R

September 1st, 2010

As time goes by and big power GT-Rs get more plentiful more and more tuners are running into the same old pesky problems. In fact, whenever you see horsepower at these levels this problem tends to rear it’s head. That is flaky air flow sensors, air flow sensors that lack resolution or airflow sensors that just max out way earlier than needed.

To put this problem to bed AMS have tackled it head on;

The AMS Nissan GT-R upgraded MAF sensor was designed to eliminate the driveabilty problems with big horsepower GT-R’s. As with any GT-R, once you start to reach the 800HP threshold, driveablity problems occur. AMS diagnosed these issues and quickly sorted out a solution. Thanks to our tuner Chris Black, we now have a MAF sensor capable of handling big power and big amounts of air. Kiss your P0700 codes goodbye! Stop dealing with rough driveablity problems if you are running Greddy 20G’s, big bolt-on turbos or full turbo kits. These Mass Air Flow Sensors are designed and calibrated to handle big power!

These babies are good to handle airflow levels up to 1200bhp and are retailing for $999.95. Hit up the AMS website linked below for the full details…

Top Racing Give Us the Lowdown on the HKS F-Con V-Pro for the GT-R

May 5th, 2010

Recently a representative of HKS Japan, Mr Suzuki, came to Top Racing Hong Kong “GT-R professional workshop” to make the announcement that the release of the HKS F-con V-Pro and F-con IS is set for mid to late June.

Top Racing was given a unit of F-con V-Pro to conduct tuning tests on the R35 GT-R and were impressed with the results. The V- Pro was installed on a R35 with the HKS GT600 kit installed, and during peak power there was a 20 horsepower gained. On our dyno, we were able to achieve 619.3 horsepower, and we can see a complete power up throughout the rev range.

The F-Con V-Pro is a full computer and completely replaces the standard ECU in the R35. It is plug and play, so installation is very straight forward. At the same time, this V-Pro comes with the HKS Valcon system, it allows the tuner to adjust the engine’s VCT system, which dramatically improves the low and mid range torque. With the ability to fine tune the fuel map, allows better fuel consumption and of course improves the power throughout the RPM. It’s again one big step in computer tuning for the R35.

We weren’t unable to conduct any test with the F-con IS. But technically speaking the F-Con IS is a sub-computer and runs off the stock one, but at the same time also allow the tuner to use the HKS Valcon system. The only differences is that you will need to run a OSC (Oxygen Signal Computer) to run the F-Con IS, this is due to the strong A/F close loop circuit the stock eco runs.. We believe that the power output between the two comp shouldn’t differ greatly, but the F-Con V-Pro will have more potential for tuning.

COBB Tuning AccessPORT Powering the GOTO:Racing Time Attack GT-R

January 19th, 2010

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.

AutoSport Wiring ECU Patch Harness for Nissan GT-R

December 3rd, 2009

img_200205

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.

Hit up the link below to order yours…

RH9 Club Members Collaborate on R35 GT-R ECU Upgrades

September 10th, 2009

phoenix-power-dyno

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.

Thanks to Mindlessoath for the email tip.

Haltech Release Platinum Pro ECU for Nissan R35 GT-R

June 17th, 2009

haltech-gtr-001

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.

gtc-ukgtr-001

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!

Nismo Sports Resetting ECU and TCM for Nissan GT-R

May 15th, 2009

nismo-ecu-r35-001

Nissan’s motorsports arm, Nismo, has announced it will be offering a warranty backed ECU and Transmission Control Module (TCM) upgrade for Nissan GT-R and GT-R SpecV owners in Japan. The upgrade is available separate to previous Nismo offerings for the Nissan GT-R such as the Nismo Clubsport Package and introduces a couple of interesting changes:

  • Improved low end torque and response from modified ECU maps
  • Increased maximum boost pressure (0.1 bar) and increased low end boost
  • Improved, quicker, downshifts
  • Street speed limiter raised to 320km/h

There is a few caveats however which will limit the interest for non-Japanese residents for now. Nismo will not sell you this ECU and TCM, they will rent it to you for the period of 24 months. While you’re renting it your factory warranty is still good and is backed by Nismo’s own guarantee. When you’re done, Nismo return your original ECU and TCM to your car.

The price for the initial 24 month period is 294,000 yen for both the base and SpecV versions with an additional fee of 31,500 per year if you continue on past the 24 months.

Available for pre-order come June 1st 2009, deliveries begin on the 24th of June.

While it’s always good to see Nismo producing parts and backing them with a warranty, the whole concept just seems incredibly bizzare to me. Renting tuning parts?

What do you guys think?
