COBB Tuning is proud to announce the availability of an innovative new pair of Internal Wastegate (IWG) Brackets for Subaru and MAZDASPEED vehicles in short and long bracket styles. The COBB Tuning Adjustable IWG Bracket is the first of its kind, and the most versatile and reliable way to keep a turbocharger’s internal wastegate closed when using an external wastegate setup. The Adjustable IWG Bracket can be installed quickly, adjusted for perfect fitment on many different turbos, and can be removed just as easily to return a turbo to its original configuration.
The COBB Adjustable IWG Bracket replaces the internal wastegate actuator and locks the wastegate in a fully closed position. This is a superior solution to welding the wastegate door closed, which is a time-consuming, expensive and irreversible process. The COBB Adjustable IWG Bracket is easy to install and bolts into place and adjusts quickly using simple hand tools.
Not all turbos are made exactly the same, and there can be variations in housings, center cartridges, clocking, etc. A single position internal wastegate bracket may not accommodate these variations and fail to close the wastegate completely, which will result in poor turbo response and lower maximum boost. The COBB Adjustable IWG Bracket takes the worry of turbo-component variance out of the equation and allows proper adjustment, every time, on a variety of different turbos that a non-adjustable internal wastegate bracket simply cannot match.
The COBB Adjustable IWG Bracket’s advantage lies in its unique adjustable rod-end linkage. The turnbuckle center section features right-hand and left-hand threads to make adjustment as easy as rotating it one direction or the other to shorten or lengthen it. The rod-end linkage and through-bolt allow high misalignment for maximum adjustability. The bracket itself is made from a single piece of 11-Gauge steel and incorporates slotted bolt holes for additional adjustability and turbo compatibility. The custom spade-bolt that connects to the wastegate arm, the bracket, and the turnbuckle are black zinc coated for an attractive finish that is corrosion resistant. All hardware for install is included in this kit.
The COBB Tuning Adjustable IWG Bracket offers maximum turbo compatibility, simple installation and is easily adjustable to ensure complete wastegate closure to get the maximum performance from your specific setup. In the familiar words of our dads, “Make sure you shut the damned door!”

Top Scoob is an occasional themed contest on NASIOC Forum where users vote for their favorite cars. NASIOC’s Top Scoob 029 for Christmas and the Quarter Mile saw several very fast and great looking Subarus competing for the top spot. When the dust settled, Matt Kincaid’s 9 second bugeye WRX finished on top, just like it does at most events in the Pacific North West. Matt bought the car brand new in 2001 and reached his first goal of a 10 second pass in full street trim by 2009. With help from COBB Tuning Surgeline, the car was prepped for a season full of 9 second passes in 2011. For 2012 and beyond, Matt hopes to reach 8 second 1/4 mile times with help from his sponsors: COBB Tuning Surgeline, Advanced Clutch Technology, DCCDPro, Pacific Import Auto, T-Mac Performance, Extreme Turbo Systems, and Thunder Bolt Racing Fuels. Read more details about the car on NASIOC and check out what COBB Tuning Surgeline is up to on Facebook.
The COBB Tuning MAF Block-Off Plate Kit is the perfect complement to Speed Density tuning. Speed Density tuned vehicles use a Manifold Absolute Pressure (MAP) sensor to monitor the mass of ingested air instead of the OEM Mass Airflow (MAF) sensors, which means the MAF sensors can be removed from the intake tubes. Removing the MAF sensors eliminates points of restriction and turbulence in the intake tract, but can present additional issues if not done properly. The COBB Tuning MAF Block-Off Plates are the easiest way to safely delete the MAF sensors for optimal performance and enhanced engine bay appearance.
We start with billet 6061 T6 aluminum and CNC-machine a plate/plug to seal off the openings left when the MAF sensors are removed. The plug has two unique features that are key to reliable performance. The first is an O-ring that tightly seals the Block-Off Plate to the MAF sensor opening, preventing unfiltered air from entering the intake tract. The second feature is the shape of the plug face, which is sculpted to exactly match the inside curve of the MAF tube. When seated, the plug completey fills the MAF sensor opening and the face sits flush with the inside of the MAF tube. This provides smooth, uninterrupted walls that prevent turbulence.
The COBB MAF Block-Off Plates are hard anodized in black for a durable, corrosion resistant finish. The Block-Off Plates then go back on the CNC mill for a final pass to have the COBB logo machined into their top faces. The kits are finished off with stainless steel button-head screws and black nylon washers that give the plates a professional appearance when installed. The COBB MAF Block-Off Plate Kits work with stock intakes, COBB SF Intakes, and any direct replacement intake with an inner diameter similar to stock.

COBB Tuning is proud to announce the immediate availability of our self-tuning proprietary Speed Density (SD) tuning solution for all currently-supported 2.5L USDM turbocharged Subaru vehicles! This capability is available as a free update to our AccessTUNER Race software and AccessPORT firmware. Our implementation of Speed Density adds our proprietary tuning logic to the factory ECU, enabling it to calculate load, ignition and fueling requirements using the engine’s manifold absolute pressure (MAP) sensor, instead of the factory mass airflow (MAF) sensor. COBB Tuning’s exclusive Realtime tuning capabilities and Hybrid Logic (active switching between MAP and MAF based logic) make this a uniquely powerful and flexible engine management solution. Read on for more details about the work COBB Tuning is doing to make sure the AccessPORT is the most comprehensive OEM ECU tuning solution available for Subaru performance enthusiasts.
Why Speed Density
The most basic function of an engine control unit (ECU) is to measure airflow and its translation to engine load. Precise and consistent load calculations along with feedback from other critical sensors allow the ECU to accurately control ignition timing, variable camshafts, and fuel delivery. The most common way to measure load in modern vehicles is with a MAF sensor. Vehicles with stock engines and mild upgrades can utilize the MAF sensor with excellent overall results. However, in big-build and motorsports applications where power levels are extremely high and intake airflow configurations are less standardized, the use of a MAF sensor can be limiting.
Speed Density tuning using the Subaru factory ECU is a major break-through for high-power Subaru builds. High-power builds using the OEM MAF sensor require very large MAF intake housings to keep the MAF sensor within its usable range, which introduces reduced resolution and unpredictable turbulence that can affect tunability and drivability. Eliminating the need for a very large, high-quality MAF intake housing, Speed Density tuning logic allows for more flexibility when designing a turbo kit and the associated piping and plumbing. Speed Density tuning gives precise control over fueling, timing and other critical tuning components necessary to properly calibrate the vehicle at the very high power levels that today’s big Subaru builds are capable of producing.
Hybrid Logic – Ultimate Flexibility
The Speed Density update for AccessTUNER Race software offers multiple ECU control modes to give the enthusiast-tuner and AccessPORT user a wider choice of engine modifications and tuning options. The software can program the ECU to run in the traditional pure MAF mode, a pure “Speed Density” mode, or a Hybrid Mode which uses both MAF and “Speed Density” with dynamic logic switching between the two.
Ease of Conversion
In order to make the transition to Speed Density as painless as possible, COBB Tuning has streamlined the process within the AccessTUNER software. Simply open an existing MAF-based calibration using the new Speed Density enabled software and resave the map. All of the tables from the MAF-based calibration will be loaded into the Speed Density based calibration. You are now ready to start tuning the Volumetric Efficiency (VE) table without the need of starting a new calibration from scratch!
COBB Tuning’s Speed Density for 2.5L Subarus has already proven capable of tuning big-power Subaru engines. The LIC Motorsports 2004 Subaru STI Time Attack race car claimed the Modified AWD class victory and set a new Modified AWD class record at the Infineon Raceway Global Time Attack 2011 season finale using the AccessPORT and Speed Density tuning. More information about this performance is available HERE.
Speed Density Availability
This release of Speed Density brings the same MAP-based tuning capabilities enjoyed by professional tuning shops to enthusiast-tuners using AccessTUNER Race software. “Off-The-Shelf” maps will not be made available for Speed Density as custom calibration specific to each vehicle is required.
Currently, the following USDM 2.5L turbocharged Subaru vehicles are supported:
- 2008-2012 STI
- 2004-2007 STI
- 2008-2012 WRX
- 2006-2007 WRX
- 2007-2011 Forester XT
- 2004-2006 Forester XT
- 2007-2011 Legacy GT
- 2005-2006 Legacy GT
- 2009 Impreza GT / 2.5GT
We are in the process of investigating the feasibility of implementing Speed Density on 2.0L turbocharged Subaru vehicles. More information on this will be available soon.
To prepare your AccessPORT and AccessTUNER software for Speed Density tuning, simply follow these steps:
- Update your AccessTUNER Race software to version 18.104.22.168-3306 (or later). To update your software follow this Step-By-Step AccessTUNER Update Guide.
- Update your AccessPORT firmware to version 22.214.171.124-3162 (or later). To update your firmware follow this Step-By-Step AccessPORT Firmware Update Tutorial.
We are very excited to bring this capability to our self-tuners through AccessTUNER Race. We have combined our proprietary Speed Density logic with the flexibility of Hybrid Mode dynamic logic switching, the convenience of the AccessPORT’s Realtime tuning capabilities and the sophistication inherent in the factory ECU, bringing a powerful and unique solution to meet a large and long-standing demand in the Subaru enthusiast community. We would like to thank you for your patience and want to hear your feedback regarding Speed Density on your Subaru!
