Supported Vehicles:
*To confirm your model year, you can refer to the tenth value in the VIN number on the vehicle. For model year 2001-2009, the 10th value in the VIN will be the last digit of the model year. For model year 2010-2019, the 10th value in the VIN will be A-K, starting with 2010, ending with 2019.

Fuel Requirements:
Each map lists the minimum required octane. A higher octane fuel can be used safely on a map designed for lower octane. DO NOT use maps designed for higher octane with lower octane fuels. Top Tier gasoline should be used where available.
Running 0% Ethanol Fuels These maps are designed for E10 fuel (fuel with 10% ethanol content). For those who only have access to E0 fuel (fuel with 0% ethanol) it is recommended to use the "91" and "ACN91" octane versions of the maps and datalog the car to ensure your fuel is performing to the necessary level. This is especially important for those using Canadian 94 octane E0 fuel.

Revision: | Notes: |
|---|
v401 | Stage2+ NexGen release | v400 | This map was updated to eliminate unnecessary DTC Supression or update versions for parity with other maps/vehicles within the platform | v361 | Adjusted fuel based protection system that operates at low DAM. No impact on normal operation. | v360 | All VA WRX calibrations updated with new CCF2 ROM family and improvements noted in v350 (previously only for 2020 WRX), plus the following: Normal, LWG, and HWG calibration options for all stages Incorporated OEM Battery life improvements to applicable models (15-17)
| v351 | Improved high load driveability. | v350 | Maps have been updated to eliminate unnecessary DTC suppression. 2020 WRX OTS utilized new CCF2 ROM family for improved driveability. Some of the changes include: Improved closed-loop fueling and learning, improved airflow calculation and fuel targets. Improved charge temperature based boost target and control, and ignition compensation. Per gear timing and boost control, improved knock learning. "Soft" boost limit (via throttle), smoothed boost control input, reduced boost reduction at low air temperatures. Improved Anti-theft map (no start), improved Valet map (more restrictions i.e. 70 MPH speed limit) Additional groundwork to help Protuners
| v303 | 2018 ADM WRX: Fixed bug where the "Intake Temperature Pre-Turbo" monitor could sometimes show a value of -58F for a brief period of time after engine start. ECU did not use the erroneous value so this is a monitor issue only. Added 2019 ADM WRX support.
| v302 | 2017 USDM WRX CVT/MT: Fixed an issue where real-time tuning and real-time map switching was disabled for the "MAF Calibration" table which caused the ECU to always use the reflashed values only for this table. | v301 | | v300 | Supports the latest Subaru ECU revision. Merged Subaru calibration for the latest injector timing changes. | v201 | Fixed bug causing Realtime map switching to not work. Added 2016 USDM WRX 6MT support. Added COBB BigSF Intake support.
| v200 | Realtime tuning/map change feature added to v200 and later OTS maps (also requires latest Accessport firmware update to expose real-time map change function). Launch control (AP and cruise control adjustable) feature added to v200 and later OTS maps (also requires latest Accessport firmware update to expose launch RPM adjustment menu). Flat foot shifting (AP adjustable) feature added to v200 and later OTS maps (also requires the latest Accessport firmware update to expose flat-foot shift RPM adjustment menu). Merged Subaru calibration update for injector timing and other changes. Includes Subaru pre-ignition updates.
| v115 | Renamed Stage1+TBE maps to Stage2 Revised IAT vs. WGDC compensation to reduce underboosting between 32 F / 0 C and -40 F / -40 C Disabled Global A/F Learning #1 adjustment Slight revision to reduce DAM adjustment sensitivity at low loads Corrected issue with OL Enrichment vs. DAM fueling adjustment table
| v114 | Addresses an infrequent brief interruption of torque/power delivery introduced in the v113 maps. | v113 | Adds support for newest factory ECU/ROM update Reduced "rev hang" behavior when changing gears Optimized higher load ignition timing Revised how IAT vs. Ignition Timing compensations are applied at low load and RPM Changed long-term fuel trim behaviors at higher load values Improved AVCS and Requested Torque settings to improve power past 6000 RPM Revised Boost Target and WGDC vs. Baro. Comps to increase boost at high elevations Altered Per-Gear Ignition Timing compensations for 4/5/6th gears at high RPM for better resistance to detonation Slightly richer target AFR at high load and RPM
| v109 | Revised low load/RPM timing to reduce knock corrections Smoothed Boost vs. IAT compensations for more predictable boost targeting Reduced Boost Target at higher RPM to raise knock threshold Adjusted Boost Target and WGDC Compensations for high elevations to address underboosting Added "High Waste Gate" secondary option mapping for cars experiencing persistent underboosting conditions Revised throttle mapping to increase sensitivity at partial accelerator pedal positions based on feedback from Airboy and others Richer target AFR at high load for increased detonation resistance
| v105 | Revised ignition timing, primary fueling, camshaft timing, closed / open loop transition thresholds and boost levels for performance and safety. Optimized throttle mapping for improved take-off and more linear response across accelerator pedal range. Factory fueling and timing strategies streamlined for ease-of-calibration and consistency following a key-off and restart sequence. Per-Gear Timing Compensations revised for safety and enabled for 6th gear (OEM logic only allows for compensating gears 1-5).

v401 | Stage+ NexGen release | v400 | This map was updated to eliminate unnecessary DTC Supression or update versions for parity with other maps/vehicles within the platform | v361 | Adjusted fuel based protection system that operates at low DAM. No impact on normal operation. | v360 | Updated all CVT WRX vehicles to CCF2 ROM Family maps. Among those changes. | v350 | | v302 | 2017 USDM WRX CVT/MT: Fixed an issue where real-time tuning and real-time map switching was disabled for the "MAF Calibration" table which caused the ECU to always use the reflashed values only for this table. | v301 | Fixed bugs associated with v300 maps preventing real-time and launch control feature changes from working. | v300 | Supports latest Subaru ECU revision. | v201 | Fixed bug causing Realtime map switching to not work. Added 2016 USDM WRX CVT support. Added COBB BigSF Intake support.
