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!

COBB Tuning has just released a firmware update for all AP-MAZ-002 AccessPORTs (07-12 MAZDASPEED3 and 06-07 MAZDASPEED6) that fixes a communications issue between the AccessPORT and the ECU, which can cause the AccessPORT to go into Recovery Mode prematurely. Once this occurs, the AccessPORT must be shipped to COBB Tuning for service. Firmware 1.6.5.0-3154 fixes this issue. We recommend updating to this latest firmware to prevent the AccessPORT from entering into Recovery Mode prematurely, which will cause several days of downtime due to shipping time and service time.

If you are unfamiliar with updating the firmware on your AccessPORT, please follow this link for Step-By-Step Firmware Update Instructions. Please feel free to contact us at 866-922-3059 or at tech@cobbtuning.com if you have any questions regarding this firmware update.

New Stage2+FMIC Stock Throttle Maps

Based on customer feedback, we have released the first of our Stage2 maps with the stock BMW throttle profile. The Stage2+FMIC maps now have the choice of factory stock throttle mapping or COBB Tuning’s linear throttle mapping. The factory stock throttle mapping is non-linear and tends to be much more aggressive in the initial range of throttle pedal. This throttle mapping gives drivers that “kick in the pants” feel of power ramping up very quickly. The COBB Tuning linear throttle mapping keeps throttle profile linear across the entire range of the throttle pedal. Linear throttle is more appropriate for driving on a race track or for drivers that prefer a very predictable and consistent throttle pedal throughout the entire range. These new stock throttle Stage2+FMIC ST
maps can be downloaded from the BMW AccessPORT Map Database. Follow this Step-By-Step AccessPORT Map Download and Transfer Guide to download maps, transfer them to your AccessPORT and flash them to your ECU.

A brand-new motor, a rain-slick track, and rivals running quicker lap times are not the best elements to make for a successful racing weekend. The LIC Motorsports and their Subaru STi were facing an uphill battle for Global Time Attack’s 2011 Finals at Infineon Raceway, but with the hard work of the LIC Motorsports crew, and some help from COBB Tuning’s Gary Sheehan and Tim Bailey, everything came together perfectly. Not only did LIC Motorsports take home 1st Place, but they set a new class record utilizing an impressive chassis and AccessPORT Alpha Speed Density Tuning.

Adam and Noah Levy of LIC Motorsports needed a motor to match the chassis development from the previous seasons of racing. The motor build was completed using a sleeved block, pistons, bearings, a GTX turbo, and a higher capacity oil pan. LIC Motorsports also decided to eliminate the BPV to increase turbo and throttle input response. Everything was buttoned up only 10 hours before hitting the track. The outcome? “Power delivery is awesome!” Gary Sheehan was also impressed with the driveability of the car compared to previous years. “The car is now very stable and predictable on corner-exit, allowing me to accelerate out of the corners hard.”

Tim Bailey of COBB Tuning took advantage of the new AccessPORT Speed Density tuning, currently in Alpha testing, to ensure the LIC Motorsports STi could optimize the upgraded engine internals. COBB Tuning’s AccessPORT Alpha Speed Density is able to eliminate the mass airflow sensor and use a comprehensive volumetric efficiency model to calculate airflow and load based upon manifold pressure and temperature. This combination offers a simple solution for tuning high horsepower vehicles. An experienced tuner like Tim Bailey can take advantage of any tuning software to create a great running vehicle, but his response to the AccessPORT Alpha Speed Density software was telling: “In a word, it is nothing short of elegant.”

The final piece of the puzzle came together with the race weekend management from LIC Motorsports. After putting together a great car, it only took a long Friday night and a few alignment adjustments to get the car where it needed to be. The result was an almost perfect Saturday! Gary Sheehan was able to push the team in to 1st place with a Limited AWD class track record of 1:41.888 and a giant gap of 1.3 seconds to 2nd place. But, “The Underdogs” know one win doesn’t warrant gloating. Noah says “It’s doing it consistently and systematically…time proves if we are a force to be reckoned with. If we have the means to continue down this path, we will ensure this becomes the norm for our team.” This success also helps emphasize to their customers that “standalone ECUs are not necessary when there is a product like the COBB AccessPORT.”
