COBB Tuning is proud to announce new updates to Nissan GT-R AccessPORT firmware and Off-the-Shelf (OTS) maps that allow gear and throttle position dependent boost control! This new “throttle and gear wastegate multiplier” effectively allows the user to limit boost onset for a given throttle position. These new features will help users prevent mid-corner snap oversteer from boost onset, even though the car is at part-throttle.

This throttle position-dependent traction control will allow drivers to apply power more smoothly, reducing sudden loss of traction due to rapid turbo spool for more effective throttle modulation. This is particularly effective for part-throttle modulation during cornering.

Both firmware and OTS calibrations have been updated to utilize this new feature. Users with older firmware and maps must update their AccessPORT and calibrations to install this new feature. Vehicles with Protuned maps must be updated by your tuner.

Gear and Throttle Wastegate Multiplier:

The gear and throttle wastegate multiplier is a gear and throttle position-dependent boost control strategy that behaves like traction control. However, instead of using the brakes and other conventional drivetrain-based methods to limit wheel spin, the ECU alters wastegate duty cycle to limit turbo spool. This in turn limits toque and power output effectively limiting low-end torque and wheel spin.

The COBB Tuning OTS maps are designed to limit full boost at part throttle for better power modulation at half throttle. However, these new tables allow for both gear AND throttle dependent boost control so that boost can be limited both by gear selection and throttle position to suit the user’s driving style.

FEATURES AND UPDATES

New Base Maps

Refined boost control based on gear and throttle position (control over tire traction in lower gears).

• Maps are available with this firmware update or can alternatively be downloaded from the GT-R AccessPORT Map Database.
• Version 2.01 map updates available for all Supported GT-Rs:
  • ADM 2009-10 GT-R

Pass-Through Tuning

Improved tuner workflow by by-passing the necessity to use AP Manager (Connect the AP to PC via usb cable and AP to car via OBD cable). Allow the AP to boot to main menu (AP must be in main menu in order for any pass-through tuning to work, AP will show a busy-screen when in Pass-Through Mode.

Flash Map

Pass-Through tuning removes the necessity of having to use AP Manager to transfer maps during tuning. This allows tuners to connect their AccessPORT to the PC and car simultaneously and allow for map flashing and map transfer without having to use additional tools outside of tuner.

Important Notes

Please make sure your AccessPORT is updated to version 1.6.1.0-13514 for compatibility with new OTS maps and new Pro Tuner software. Instructions for updating your firmware can be found on the Nissan GT-R AccessPORT Firmware Page.

Whitney Edmister is a GT-R owner and racer. Not only does he drive this 2009 GT-R on the street, but he is racing it in the Redline Time Attack in the Modified Class. Whitney’s car is a great example of what the dedicated enthusiast can do with a well-prepared machine and a COBB Tuning AccessPORT!

When I started to upgrade my 2009 GTR for the track, I started out with the wheels, tires, and brakes. After just three track days on the stock tires, I had nearly worn them out. We wanted to have a second set of lighter wheels and tires for the track, and keep the stock tires on the stock rims for street use only. We upgraded the brakes with Carbotec pads, AP racing rotors, Stillen stainless brake lines, and Motul racing brake fluid. This completely eliminated brake fade and allowed crisp, hard braking, even toward the end of a 30-minute track session with rotors at 550F. All of our upgrades were installed by Palladin Advanced Automotive in Las Vegas.

The first suspension upgrade we did was to install the Cobb antisway bars. This allowed us to reduce the roll in the rear and eliminate the stock understeer. There’s nothing more frustrating than driving hard into a corner, braking hard, turning the wheel, and the car keeps going straight ahead, pushing wide through the corner! Now with slight oversteer, the front end carves right around, and the rear end follows. The reduced body roll and negative camber keeps the outside tires in contact with the pavement through the turn. Adding the JRZ RSpro suspension and lowering the car slightly gave us the stability and control we needed to drive the car to the limit.

We wanted to improve engine performance as well, but didn’t want to spend a lot of money upgrading the engine and tuning. First we freed up the exhaust with the HKS Legamax midpipe and catback exhaust. It’s a stainless system with titanium tips that is lightweight, high flow, and looks and sounds great. This took the exhaust from nearly silent to a beautiful, deep note. Next we installed the COBB Tuning AccessPORT and flashed ECU with the 91 octane, Stage 2 map. Immediately we noticed improved torque, acceleration, and boost, and a dramatic improvement in lap times. Next we upgraded to the 100 octane, Stage 2 map with 100 octane racing fuel. We were amazed that this second upgrade gave us another performance boost that felt just as significant as the first. Just installing the AccessPORT with or without a high-flow exhaust is the most cost-effective performance upgrade you can make to the GTR. According to COBB, we should be making 550hp with our configuration, but have not put the car on the dyno yet.

In Las Vegas, we ran the GT-R in the Modified class of the Redline Time Attack and was highly competitive despite just our few targeted upgrades. The car felt perfectly balanced with terrific acceleration and braking. When braking into the corner, the rear end felt light and the car turned in easily. The rear end came right around with slight oversteer. Once I was confident of hitting the apexes properly, I added a little throttle shifted weight to the rear, locking the car down, followed by hard acceleration through the apex into the next straight. At the end of the front and back straights, we were hitting speeds up to 135 mph. The track was highly techinical with hairpins, carousel turns, and even a chicane, but the GTR carved up the 2.4 mile road course. Our lap times continued to improve through the two days, with our best lap time of 1:50.0. It was a great weekend to race such a fast and capable car.

COBB Tuning has just released an AccessPORT firmware update for the 2004-2007 STI, 2006-2007 Subaru WRX, 2004-2006 Forester XT and 2005-2006 Legacy GT (AP-SUB-002). This update repairs a minor bugs with the AccessPORT, adds new functions and streamlines the menu screens. This update supports v2 and v2b units, meaning that both versions use the same firmware release: 1.6.0.0-12852. In addition, all “BETA” versions have been consolidated into this update. The bug fix in this release resolves the AP slowdown associated with extensive use.

URGENT – Resolves the AccessPORT slowdown associated with extensive use, which can eventually render the AccessPORT non-functional, requiring it to be sent to COBB Tuning for repair.

The “About” screen on both v2 and v2b has been simplified for easier interpretation and support and the “Change Map” feature has been updated for both units to give an explanation for any greyed-out “locked-out” maps.

This update is available immediately through AccessPORT Updater and requires no other updates to maps or tuning software be performed. Further information can be found on our Firmware Information Page.
