COBB Tuning is proud to announce the immediate availability of our 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 Pro 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 using 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 Pro software offers multiple ECU control modes to give the professional 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!

Proven Performance
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 and in-car action can be seen HERE.

Speed Density Availability
This initial release of Speed Density is available for professional tuning shops using AccessTUNER Pro software for turbocharged Subaru USDM vehicles. Speed Density for AccessTUNER Race is currently in development and will be made available to self-tuners once development and testing is completed. “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 have your vehicle tuned using Speed Density logic, simply follow these steps:

• Contact your preferred ProTUNER, confirm they have the latest Speed Density enabled AccessTUNER Pro software and schedule a Speed Density dyno-tune appointment with them.
• Update your AccessPORT firmware to version 1.6.4.0-3162 (or later) prior to your scheduled tuning appointment. To update your firmware follow this Step-By-Step AccessPORT Firmware Update Tutorial.

It took us quite a bit longer than anticipated to develop Speed Density for all USDM 2.5L turbocharged Subaru vehicles, but now that it is complete, we are very excited about this release. 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!

To learn more about our implementation of Speed Density, please download the Subaru 2.5L Speed Density Tuning Guide. If you are interested in becoming a new Subaru ProTUNER capable of tuning customer vehicles with Speed Density, please give us a call at 866-922-3059.

EDIT 10/7/11: As noted by a few readers, the build work was done by Craven Performance in St.Peters, MO and AMS Performance did the tuning.

AMS Performance recently finished a 653 WHP 2011 STI sedan build that is running low 11 second 1/4-mile times! Their customer, James from St. Louis, wanted a big horsepower Subaru, but needed it to drive like the stock vehicle since the car is still a daily driver. The build started with the AMS 900HP Shortblock, built heads with Cosworth cams, Injector Dynamics ID2000cc injectors, and the AMS 950R turbo kit. For tuning, AMS relied on the COBB Tuning AccessPORT and AccessTUNER Pro for it’s ease of use, real time tuning, graphical interface, and customer support.

So what does it take to make over 600 wheel horsepower and still be able to make the car perform well as a daily driver? “It takes a good amount of time to dial in the large MAF paired with large injectors” said Mitch Mckee, an AMS Performance ECU Calibrator. Mitch also noted that “some people like kill mode all of the time”, but using the map switching abilities of the AccessPORT, he can create multiple boost level maps since most customers prefer to have it “turned down just a bit for softer driving when on the street.”

“It drives like stock on E85, just much faster!” Using the AccessPORT, James can switch between E85 and 93 octane maps for the track or street. When at the drag strip, he takes full advantage of the AccessPORT’s Launch Control and Flat Foot Shifting features. James noted the AccessPORT datalogging “makes it easy to communicate back and forth with my tuner even though he is 300 miles away.”

Check out the video above of James’s STI at the drag strip! Don’t forget to check out AMS Performance and if you want to learn more about the AccessPORT and it’s features, just visit COBB Tuning.

If your ECU is not recognized using this firmware, please notify us promptly so that we can get you into the BMW AccessPORT family ASAP!

Bug Fix

The v300 maps revealed issues some customers have experienced, such as a possible limp mode when accelerating hard at higher rates of speed and slight surging at part throttle when the motor is cold. A torque limit threshold was adjusted to eliminate the potential limp mode and a fuel based load compensation was changed to smooth out the partial throttle drivability.

These new BMW performance calibrations and ROM support for your COBB Tuning AccessPORT are available for download or via our latest AccessPORT firmware update. To update your AccessPORT to the latest firmware, simply open the AccessPORT Manager application, connect your AccessPORT to your computer via the supplied USB cable, then click on the “Updates” menu icon and follow the on-screen prompts. These new features will be installed automatically. If you do not have AccessPORT Manager, you can find the download link for your free copy on our Support Page. To complete the update, flash one of the new v3.01 calibrations to your ECU. Using older maps with this update may cause poor performance or unexpected issues.

COBB Tuning is happy to announce new features and calibration updates for all MAZDASPEED vehicles. This update includes Boost Tuning for 1st Gen (2007-2009) MAZDASPEED3s, Launch Control and Flat Foot Shifting enabled for 2nd Gen (2010-2011) MAZDASPEED3 and Fast Data Logging for all MAZDASPEED3s and MAZDASPEED6s. Boost Tuning logic for the MAZDASPEED6 is still in development and will be released at a later date.

These features are available through a combination firmware updates and new maps. The updated maps for the MAZDASPEED3 are available for Stage1 and Stage2 cars with the stock intake, the COBB SF intake and several other intakes as well as calibrations for turbo inlet pipes, intercoolers and other go-fast, bolt-on parts. Now every model year of the MAZDASPEED3 line-up has over 110 Off-The-Shelf maps to choose from, making the AccessPORT the leader in plug-and-play ECU tuning!

Boost Tuning

COBB Tuning is the leading innovator in MAZDASPEED3  aftermarket performance ECU Tuning. Our proprietary industry-leading Boost Tuning logic has performed extremely well on the 2010-2011 MAZDASPEED3 vehicles. Over the past several months we have offered Boost Tuning calibrations and tuning software in BETA format for the 2007-2009 MAZDASPEED3 with very positive results. These calibrations are now available in final release form, giving 2007-2009 MAZDASPEED3 owners the superior performance of Boost Tuning and over 110 maps to choose from!  In addition, current non-boost tuning calibrations can be converted via AccessTUNER for better boost control.

The stock ECU logic uses load targets to determine power output and dynamically adjusts boost pressure to meet those targets. Early on, COBB Tuning recognized that this was a cumbersome way of controlling boost and could result in erratic boost control and sub-optimal performance. To rectify this, COBB Tuning developed new logic instructing the ECU to target boost instead of load.

This “Boost Tuning” strategy allows for much more consistent boost control for a more linear and consistent boost curve which means improved power delivery for your MAZDASPEED vehicle. Boost Tuning on the OEM ECU is ONLY available on the COBB Tuning AccessPORT.

Launch Control and Flat Foot Shifting

COBB Tuning is pleased to announce the availability of Launch Control and Flat-Foot Shifting for 2nd Gen (2010-2011) MAZDASPEED3s. Launch Control limits engine RPM to a user-set value when launching to build boost and increase launch consistency. Flat-Foot Shift allows the user to maintain wide-open-throttle during gear changes, keeping partial boost between shifts and improving acceleration post-shift.

This firmware release enables Launch Control and Flat Foot shifting on 2nd Gen MAZDASPEED3’s and sets the limits at the factory rev limiter. The latest release of AccessTUNER software allows the Launch Control and Flat Foot Shifting limiters to be adjusted and saved in the map. Click this link to learn more about the latest MAZDASPEED AccessTUNER release.

Fast Data Logging

This update also includes Fast Data Logging for all MAZDASPEED AccessPORTs. Faster datalogging means more resolution in data logs, allowing users to see how the engine is behaving during high-speed and high-load conditions in greater detail. The Fast Data Logging feature is built into the latest maps for the MAZDASPEED3 and MAZDASPEED6 are available now for download. This feature applies to both v2 and v2b AccessPORTs.
