2013 Subaru WRX Stage 2 Firmware and Map Updates

COBB has just released new map and firmware updates for all AP-SUB-003 AccessPORTs that fixes a map issue for the 2013 WRX, STI, and Forester XT that can cause the vehicle to show a P0605 ROM Error with Stage 2 mapping. To prevent this from happening or to resolve a current issue, first you will just need to uninstall the AccessPORT from the vehicle using the Uninstall option from the main menu. Then, update the AccessPORT to the latest firmware (1.6.7.0-5151 or greater) using AP Manager. Finally, do a full Reflash map change with the newest maps on the AccessPORT or downloaded from the Maps section of our website. You can verify your current firmware by going to AccessPORT, then About and you can verify your current map version by going to Tune, then Show current Map, then Reflash Map.

For the 2013 STI, use Stage 2 map version v321 or greater. For the 2013 WRX, use Stage 2 stock intake map version v301 or greater or Stage 2+SF/AEM map version v312 or greater. For the 2013 Forester XT, use Stage 2 map version v311 or greater.

COBB AccessPORT Support for 2010 Impreza 2.5GT and Significant Subaru AccessTUNER Updates

COBB Tuning is proud to announce the latest updates for the Subaru AccessPORT and AccessTUNER suite of engine management tools. In addition to the exciting news of our Subaru 2.0L Speed Density support, this release also includes support for the 2010 Subaru Impreza 2.5GT, a new data logging and Live Data monitor for all Subaru AccessPORTs, and significant AccessTUNER enhancements across all supported Subaru vehicles. Read on to learn more about these exciting new updates and how COBB Tuning is keeping the AccessPORT at the forefront of Subaru engine management!

ACCESSPORT UPDATES

New Applications

  • 2010 2.5GT: USDM 2010 Impreza 2.5GT is now supported and has been added to AP-SUB-003. The firmware includes Stage1 and Stage2 performance maps and Non-Performance maps including Economy Mode, Valet Mode and Anti-Theft Mode. These maps are also available for download from the Subaru AccessPORT Off-The-Shelf Map Database.

Monitor Enhancements

  • Inj. PW (No Lat): The Inj. PW (No Lat) monitor was added to the firmware. This is a version of injector pulse width without injector latency and with higher precision. See software changes in next section for more details.
  • Inj. PW (w/Lat): The existing Inj. Pulse Width monitor name was changed to Inj. PW (w/ Lat). This was necessary to distinguish between this monitor and the new Inj. PW (No Lat) monitor described above.

Update Firmware

  • Existing AP-SUB-003 AccessPORTs can be updated to support the 2010 Subaru Impreza 2.5GT and all Subaru AccessPORTs can be updated to include the new Inj. PS (No Lat) monitor quickly and easily via a firmware update. If you are unfamiliar with the AccessPORT firmware update process, follow this Step-By-Step AccessPORT Firmware Update Guide. This is a general release firmware and there is no reason to update to beta firmware.

ACCESSTUNER UPDATES
 
New Tables

  • Primary Open Loop Fueling Max. Enrichment (Intake Temp)(SUB-001 ONLY): This allows for removing/tuning a newly discovered rich limit to primary open loop fueling based on intake temperature.
     
  • Fuel Injector Trim (Small IPW)(ALL SUB-002 and SUB-003): These tables govern a compensation to the final injector pulse width based on the currently calculated pulse width (when low). The factory compensation can be problematic for large aftermarket injectors and tuning this table can help with the idle issues that result.
     
  • SI-DRIVE Intelligent to Sport Mode Override (08-12 STI ONLY): These tables govern an automatic switching from intelligent SI-DRIVE mode to Sport when the accelerator pedal is held at or above the stated threshold for the period of time determined by the delay. Tuning these tables will allow you to manipulate this behavior or remove it entirely.
     
  • Rear O2 Sensor Related Closed Loop Fueling Correction Factors (ALL SUB-002 and SUB-003): The two table groups below (one or the other, used depending on ECU) allow you to tune the effects of the rear O2 sensor on fueling. This current release adds the tables to the non-SD 2.5L ECUs (previously already added to SD 2.5L ECUs).
     
    AP-SUB-002:

     
    AP-SUB-003:
  • Idle Airflow Min. Target Decel. Ramping Adder The two tables below (in addition to the other existing tables already in this category) could potentially be useful for tuning idle airflow decel behavior (on cars with aftermarket cams, for example). This current release adds the tables to the non-SD 2.5L ECUs (previously already added to SD 2.5L ECUs).
     
  • Target Throttle Angles (Idle Airflow Target) (ALL SUB-002 and SUB-003): The two table groups below (one or the other, depending on ECU), allow you to manipulate the resulting idle-based target throttle angle adder. This could be potentially useful for cars with aftermarket cams, for example. This current release adds the tables to the non-SD 2.5L ECUs (previously already added to SD 2.5L ECUs).
     
    AP-SUB-002

    AP-SUB-003

New Monitors

  • Inj. #1 Pulse Width (No Latency):The Inj. #1 Pulse Width (No Latency) monitor was added to AccessTUNER. This is a version of injector pulse width without injector latency and with higher precision. This was necessary because some of the table values, such as Fuel Injector Pulse Width Limit (Min), referenced injector pulse width without latency, which made it confusing to tuners that could only monitor the standard injector pulse width, which includes latency. This original monitor was renamed Inj. #1 Pulse Width (With Latency).

New Toggles

  • Key-On DAM Reset Toggle (10-12 Legacy GT only): The 10-12 LGT have unique logic that resets the DAM to its initial value on every key-on. Unchecking this toggle and reflashing the map will prevent this from happening.
     
  • Neutral Position Switch Invert and Fuel Pump Fault Detection Toggle (SUB-001 ONLY): Some manual transmission swaps require that the neutral position switch determination by the ECU be inverted. This can now be accomplished for the 2.0L ECU (both SD and non-SD) by unchecking the new Neutral Position Switch Invert (MT) toggle (requires map to be reflashed).
     
    Additionally, a new toggle has been added to disable (when unchecked) the Fuel Pump P0230 Fault Detection. This may be necessary with certain aftermarket fuel pump installs. Also requires that the map be reflashed.
     

Miscellaneous Changes

  • Some minor table name and unit name changes for clarity and/or consistency.
  • Some additional table sub-groups added to better organize groups with large numbers of tables or to better group tables with similar but distinct functionality.
  • (SUB-002 and SUB-003 non-SD): Lowered the maximum MAF Calibration table airflow value from 2000 g/s to 1000 g/s, to allow for better graphing of this table.
  • Some other minor changes to min or max table values.
  • (SUB-002 and SUB-003): MAP Sensor Calibration (Offset/Multiplier) table split into two separate tables.

Update Software

  • Update Existing Software: To update your existing Subaru AccessTUNER Pro or Race software, simply select Help > Updates > Check For Updates. Make sure the Beta Software box is unchecked. Follow on-screen instructions.
  • Download New Software: If you do not have a copy of AccessTUNER Race software, or your older version of AccessTUNER Race does not have the Auto-Update feature, please visit the Subaru AccessTUNER Race product page, click on the AccessTUNER Race Download Request Form link, and fill out the form in its entirety.

COBB Brings Speed Density to 2.0L Turbo Subarus

COBB Tuning is proud to announce the immediate availability of our proprietary Speed Density (SD) tuning solution for all currently-supported 2.0L USDM turbocharged Subaru vehicles with manual transmissions! This capability is available as a free update to our AccessTUNER Pro and 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 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.

Tuning Efficiency
COBB’s proprietary Speed Density implementation overcomes many of the limitations and tuning difficulties inherent to the Subaru 2.0L ECU. No longer is there a need to employ hacks to artificially raise the airflow and load limits present in the factory 2.0L ECU. These limits have been internally raised for COBB 2.0L Speed Density, allowing you to simply tune with real-world airflow values (up to 655 g/s) and load values (up to 10.0 g/rev). Additionally, in SD (Speed Density) mode, only the new load limit will come into play, allowing for the accommodation of very high horsepower builds.

We have also made improvements to boost control with 2.0L Speed Density. It is no longer necessary to move away from factory ECU boost control at higher boost levels. New internal changes allow targeting up to 49 psig of boost. We have also incorporated all-new per gear boost targets and wastegate duty compensations, allowing for more precise control of boost in each gear. These new per gear compensations are also compatible with 6-speed transmission swaps, allowing for individual manipulation of boost control in each of the 6 gears.

Tuning aftermarket injectors with COBB 2.0L Speed Density could not be easier. The “Fuel Injector Scale”, “Fuel Injector Latency”, and “Tip-in Enrichment” tables can now be tuned via real-time with COBB 2.0L Speed Density, enabling you to quickly dial in your injector tune. An all-new real-time “Fuel Injector Latency Adder” table allows for tweaking of idle and low load behavior for large aftermarket injectors, resulting in more refined operation during these conditions.

Tuning for aftermarket MAP and IAT sensors is also improved with COBB 2.0L Speed Density. Changes have been made to allow for the full calibration necessary to tune for any Subaru compatible aftermarket MAP and IAT sensors.

Proven Performance
COBB Tuning’s Speed Density for 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 and for self-tuners using AccessTUNER Race software for the 2002-2005 Subaru WRX.. “Off-The-Shelf” maps will not be made available for Speed Density as custom calibration specific to each vehicle is required.

To have your vehicle tuned using Speed Density logic, simply follow these steps:

  • Contact your preferred Pro TUNER, confirm they have the latest 2.0L Speed Density enabled AccessTUNER Pro software (1.9.1.0-4704) and schedule a Speed Density dyno-tune appointment with them
    OR
  • Update your AccessTUNER Race software to the latest version (1.9.1.0-4716) to acquire 2.0L Speed Density functionality.
  • Update your AccessPORT firmware to version 1.6.7.0-4707 (or later) prior to your scheduled tuning appointment. To update your firmware follow this Step-By-Step AccessPORT Firmware Update Tutorial.
