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.
