Subaru Accesstuner Race
Accesstuner Race is engine tuning software created for enthusiast tuners. Accesstuner Race allows the user to get into the heart of the OEM ECU and create custom calibrations for vehicles equipped with virtually any performance modification. The end result is a tune that is custom tailored to the vehicle's unique modifications, producing maximum power gains while maintaining the drive-ability and sophistication inherent in the OEM ECU.

ACCESSTUNER SUPPORT & UPDATES DOCUMENTATION:
Accesstuner Support Page
Accesstuner is capable of displaying and recording sensor data collected by the ECU during tuning sessions. Click on this Subaru Accesstuner Software USDM Monitor Descriptions document to view a full list of Data Monitors available for the supported vehicles.
SUBARU ACCESSTUNER TABLES:
Accesstuner gives access to a large number of tables to provide extensive tuning capabilities within the OEM ECU. Click on this Subaru Accesstuner Software USDM Table Descriptions document to view a full list of tables available for supported vehicles.
NEW SUBARU ACCESSTUNER RACE FEATURES:
2.0L SPEED DENSITY: Easily tune big power builds using manifold absolute pressure (MAP) sensor to measure mass of air instead of the stock mass airflow (MAF). Click to read the all-new Subaru Accesstuner Software USDM 2.0L Speed Density.
2010 IMPREZA 2.5GT SUPPORT: The 2010 Subaru Impreza 2.5GT has been added to AP-SUB-003 Accessport firmware and is now tunable through Accesstuner.
PRIMARY OPEN LOOP FUELING MAX ENRICHMENT (INTAKE TEMP) TABLET: his allows for removing/tuning a newly discovered rich limit to primary open loop fueling based on intake temperature. (AP-SUB-001 only)
FUEL INJECTOR TRIM (SMALL IPW) TABLET: hese 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. (AP-SUB-002 & AP-SUB-003)
SI-DRIVE INTELLIGENT TO SPORT MODE OVERRIDE TABLE: 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. (08-12 STI Only)
REAR O2 SENSOR RELATED CLOSED LOOP FUELING CORRECTION FACTORS TABLE: This table allows 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. This was already available for SD 2.5L ECUs. (AP-SUB-002 & AP-SUB-003)
IDLE AIRFLOW MIN. TARGET DECEL. RAMPING ADDER) TABLE: This table is 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. This was already available for SD 2.5L ECUs.
TARGET THROTTLE ANGLES (IDLE AIRFLOW TARGET) TABLE: This table allows 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. This was already available for SD 2.5L ECUs. (AP-SUB-002 & AP-SUB-003)
INJ.#1 PULSE WIDTH (NO LATENCY) MONITOR: 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.
KEY-ON DAM RESET TOGGLE: The 10-12 Legacy GTs 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 SND FUEL PUMP FAULT DETECTION TOGGLE: 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. (AP-SUB-001 only)
SUBARU ACCESSTUNER RACE TUNING FEATURES:
TUNE LIKE A PRO: Accesstuner Race provides the same tuning capabilities as our Pro software. The only differences are that Accesstuner Race does not lock maps (meaning they can be shared) and Accesstuner Race will only work with your specific Accessport.
TABLE & MONITOR ENHANCEMENTS: This latest release employs a new architecture that contains a much expanded list of monitors and tables and allows much more rapid deployment of new definitions. For a complete list of data monitors and tables available, view the new Subaru Accesstuner Monitor Definitions and Subaru Accesstuner Table Definitions documents.
2.5L SPEED DENSITY: Easily tune big power builds using manifold absolute pressure (MAP) sensor to measure mass of air instead of the stock mass airflow (MAF). Click to read the all-new Subaru Accesstuner Software USDM 2.5L Speed Density.
REAL TIME TUNING: Make value changes to real time tuning tables instantly and immediately see the results without needing to wait for a typical ECU flash.
LAUNCH CONTROL: Tuners can adjust Launch Control tables in a map for all manual transmission Subaru vehicles supported by this software.
FLAT FOOT SHIFT: Tuners can adjust Flat Foot Shift tables in a map for all manual transmission Subaru vehicles supported by this software (excluding 2002-2005 Subaru WRX).
AUTO UPDATE & ROLLBACK: Users can access tuning software updates through the "Help/Updates" menu. No longer need to download the latest tuner version to stay up to date. Software rollback to an earlier version is also enabled.
IMPROVED 3D GRAPHICS: The 3D table graphic feature has been significantly reworked to produce greatly enhanced 3D table graphs, making them much easier to view.
INTEGRAL DATA LOGGING: Unlimited data logging of multiple channels of data from the ECU for detailed analysis of engine performance
INTEGRAL DASHBOARD: Shows tuner chosen gauges to be displayed on-screen throughout the tuning process
UNIT CONVERSION: Ability to easily convert between metric and standard units so the tuner can use units he/she is most familiar with
MAP DATABASE: Free access to the OTS map database from COBB Tuning that provide excellent starting points for specific modifications
HOT KEYS: Convenient on-touch short-cut keys allow easy data manipulation of common tuning operations
WIDEBAND O2 INTERFACE: Open wideband O2 interface integrates with a wide selection of available wideband O2 sensors
EMBEDDED STOCK DATA: Stock tuning data (ROMs) are self-contained inside the software itself, providing the OEM baseline tune for each vehicle supported by the software
MAP SHARING: Maps created with Accesstuner Race can be openly shared with fellow Accesstuner Race users
WORKFLOW IMPROVEMENTS: Accesstuner has been extensively reworked to address a large number of table updates, bug fixes and changes for all Subaru models. These changes make tuning easier and more intuitive. Please view the Subaru 2.0L ECU Software Change Guide and Subaru 2.5L ECU Software Change Guide for a complete list of updates applied to each ECU type.
