COBB Tuning announces the immediate availability of the AccessPORT for the 2010 Subaru Forester XT and 2010 Subaru Legacy GT. The AccessPORT is the first hand-held device available for the 2010 Forester XT and Legacy GT that performs an ECU reflash through the vehicle’s OBDII port. Just plug it in, load a map and go! Faster!

The AccessPORT provides owners of 2010 Forester XT and Legacy GT vehicles the ability to unlock power hidden within the factory ECU. Performance gains across the entire powerband can be quickly realized in the short time it takes to flash the vehicle’s ECU with the AccessPORT. No tools are required. No additional “piggy-back” hardware. or wiring is required. No mailing the factory ECU across the country. No vehicle downtime. No waiting. Not even a computer is required. Just plug the AccessPORT in, flash the ECU and enjoy the thrill of increased torque and horsepower!

Flashing the ECU for increased performance is just the start of what the AccessPORT is capable of. Set the AccessPORT to Performance mode to capture 0-60MPH times, ¼ Mile times and Trap Speeds. Switch over to Live Data mode and choose a gauge to monitor, such as: coolant temperature, intake air temperature, throttle position, intake cam advance, exhaust cam retard, MAF voltage, injector pulse width and many more. Configure a shift light that flashes the screen when a user defined rpm is reached. Select the integrated Data Logger to record multiple channels of data simultaneously. Go to Troubleshooting mode to diagnose issues by reading the factory codes and resetting the system once the issues have been resolved.

The AccessPORT can be used to eliminate separation anxiety for those times when you are away from your car. Protect your investment when out on the town by quickly loading the Valet map to prevent the engine from revving above 3,200 rpm. Load the Anti-Theft map when you park to make it impossible to start. In the event the car must be returned to the stock configuration, the AccessPORT can be completely removed and the ECU restored to its factory condition.

AccessTUNER Pro for the 2010 Subaru Forester XT and Legacy GT is available to the COBB Pro Tuner network. AccessTUNER Pro allows professional engine tuners to custom tune any combination of modifcations to achieve the maximum power potential. AccessTUNER Race is available to racing teams and highly experienced self tuners. AccessTUNER Race allows individuals the ability to tweak their own maps at their convenience as well as the ability share maps with others that have similar power modifications. Data Logging allows multiple channels of data to be recorded and reviewed after a dynamometer or road test to see where tuning can be optimized.

The AccessPORT from COBB Tuning is the most comprehensive hand-held ECU flashing, monitoring and managing device available for the 2010 Subaru Forester XT and Legacy GT. Combined with AccessTUNER Pro and AccessTUNER Race software, it provides an unbeatable suite of engine tuning applications backed by our professional tuner network and outstanding customer support.

Satisfy your hunger for more power. Access the Potential of your 2010 Subaru today!

The COBB Tuning Motorsports STI has been undergoing a complete overhaul between Round 3 and 4 of the Redline Time Attack series. A completely new cage has been installed in the car, as well as both the engine and transmission getting a complete rebuild. The crew installed a brand new OS Giken rear differential along with a new Cosworth intake manifold and an AIM data acquisition system.

In addition the turbocharger has been upgraded to a larger exhaust housing allowing the car to make much more peak power, albeit on the same compressor and turbine. The exhaust system has also been modified, allowing the car to be lowered without infringing on the Street class rules dictating the no part of the car be lower than 3-inches off the ground. The exhaust is no longer the lowest part of the car! Watch out for Cameron’s all-new reloaded STI, it is poised to take the top of the podium at Round 4 of the Redline Time Attack at Auto Club Speedway!

The COBB Tuning Motorsports team and I just got back from our first weekend of testing at California Speedway with the new OS Giken TCD rear Limited Slip Differential (LSD) upgrade for our GT-R. With nearly 800HP available at the wheels, I had been experiencing significant rear wheel spin on corner exit that was obviously hurting the car’s ability to put power down coming out of the turns and hurting our lap times.

During the install the OS Giken LSD looked quite a bit beefier than the stock part it was replacing. Probably because it has a grand total of 28 friction plates inside! These plates can be configured to provide progressive locking up to 100% and with that many plates there are quite a lot of tuning options for us to fine tune the amount of lock-up we want.

My first impression was “WOW!” What a difference the TCD LSD made! As I started my first hot laps I could feel the difference in the rear of the car. Now the chassis just seemed to hunch down in the back and squirt out of the corners with no rear inside wheel spin at all. Plus it was much easier to use the throttle to help steer the car out of the corners. With the inside wheel spin gone, I could easily modulate rear slip angle with my right foot, encouraging corner exit rotation by feeding in just a bit more throttle.

As they say, the proof is in the data, and we have data. In this first screen shot is data from last year with the stock rear differential. Focus on the section where throttle position begins to increase and look at the difference in rear wheel speeds.  At some points there is as much as a 14 mph difference between the rear wheels. And this was on super sticky Hoosier R100 slick racing tires!

This next screen shot is from data recorded during our test day with the OS Giken TCD LSD installed. Looking at the wheel speeds you can see they are much closer together and how much the rear differential is working.  It allows a small amount of slip under deceleration, and locks up 100% under acceleration.  In fact you can see that for most of the graph the left and right rear wheel speeds are so close they are indistinguishable from each other. What makes this even more impressive is that we were running on Toyo RA1 DOT racing tires. DOT race tires are not nearly as sticky as the pure racing slicks we used last year, so it is clear to see how effective the OS Giken rear diff is, even with much less traction from the tires.

The data also revealed that we still are suffering from front wheel spin. The OS Giken rear LSD is working so well we may need to encourage them to release their forthcoming front LSD as soon as possible!

We’re in the final stages of preparation for Round 1 of the Redline Time Attack Series which kicks off this weekend, March 27 & 28, at Buttonwillow Raceway in Buttonwillow, CA. If you are in the SF Bay or LA area, come on by to say hello and stick around to see how our monstrous Nissan GT-R fares as we take on the hotly contested Modified Class.
