Map Notes for 2009-2014 WRX MT North American and ADM Spec
Supported Vehicles:
- Model year 2009-2014 WRX MT (North American, ADM Spec)
*Some Canadian Spec 2009 model year WRXs were 2008 spec car (non 265 models), and have the VF40 turbo found on the 2008 model year WRX. For power figures and gains, please view our 2008 WRX MT map notes.
**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.

Map | Peak Gains* |
---|---|
Stage1 ACN91 | +8% HP / +10% TQ over stock |

Stage1 93 | +13.5% HP / +17% TQ over stock |
Power numbers are from 93 octane mapping. Results may vary. Power as tested on 2009 - 2014 WRX vehicles using these identical calibrations. Generally speaking, the 91 (95 RON) and ACN91 calibrations run slightly lower boost, have a richer fuel curve, and a less aggressive ignition advance map to help compensate for 91 octane fuel; Arizona, California, and Nevada 91 octane fuel; and/or less than ideal atmospheric conditions. The maps designed for 93 (98 RON) octane are the most aggressive.
Stage1
- Intake Requirements: Stock airbox with stock air filter.
- Exhaust Requirements:
- Stock cat-back or COBB Titanium 515140 or Stainless 515132 cat-back exhaust
- Boost Targets:
- ACN91: ~16.0psi peak boost pressure tapering down to ~11.0psi by the 6700RPM redline, +/- 1.0psi
- 91 octane (95 RON) Minimum: ~16.5psi peak boost pressure tapering down to ~11.5psi by the 6700RPM redline, +/- 1.0psi
- 93 octane (98 RON) Minimum: ~17.0psi peak boost pressure tapering down to ~12.0psi by the 6700RPM redline, +/- 1.0psi
Stage1+SF
- Intake Requirements: COBB Tuning SF Intake 715300
- Exhaust Requirements: Stock cat-back or COBB Titanium 515140 or Stainless 515132 cat-back exhaust
- Boost Targets:
- ACN91: ~16.0psi peak boost pressure tapering down to ~11.0psi by the 6700RPM redline, +/- 1.0psi
- 91 octane (95 RON) Minimum: ~16.5psi peak boost pressure tapering down to ~11.5psi by the 6700RPM redline, +/- 1.0psi
- 93 octane (98 RON) Minimum: ~17.0psi peak boost pressure tapering down to ~12.0psi by the 6700RPM redline, +/- 1.0psi
All Stage1 performance maps now include a “HWG” and “LWG” version:
- HWG: Higher wastegate duty cycles (HWG) for use when normal wastegate calibration produces lower than targeted boost (i.e. under boost).
- LWG: Lower wastegate duty cycles (LWG) for use when normal wastegate calibration produces higher than targeted boost (i.e. over boost).
Non-Performance Maps
Anti-Theft Mode
- Will not allow vehicle to start
Economy Mode, Intake+Economy Mode
- Boost Targets: Mechanical Minimum (typically around 6psi - 12psi)
Valet Mode
- Boost Targets: Mechanical Minimum (typically around 6psi - 12psi)
- Rev Limiter: 3200 RPM
Monitoring Boost Levels:
The best way to determine if you are hitting target boost is to watch the TD Boost Error parameter. This parameter is your target boost (including altitude and temperature compensations) minus your actual boost (negative values mean you are over the target by the amount while positive values mean you are under). Ideally you want this value to be between 0 and 1.0 at wide open throttle (WOT), but -1.0 to 1.0 is acceptable assuming that you don’t have any significant knock corrections. Overboosting is more likely to occur in higher gears and with colder outside temperatures, so be sure to verify boost levels during these conditions.
High Altitude:
A quick note for those of you that live at higher altitudes. It is common for turbocharged cars at higher altitudes to run less boost pressure due to lower air pressure and air density. Your turbocharger has to work harder to compress a less dense air mass compared to the same turbocharger at sea level. This must be factored in when determining if your turbocharger is running the proper amount of boost pressure and not being pushed beyond its efficiency range.
Example: If you live in Denver at 5280 ft and are trying to run a peak boost pressure of 15 psi, your turbocharger has to work the equivalent of making ~17.5 psi at sea level.
There are barometric compensations within the factory ECU that lower boost targets as you climb in altitude in an effort to keep the turbocharger in its optimal range.The COBB performance maps utilize these compensations and therefore, it is perfectly normal for the final boost target to be lower than what is listed for your map.
Revision Notes:
Version # | Notes: |
---|---|
v400 | Maps updated to eliminate unnecessary DTC Supression or updated versions for parity with other maps/vehicles within the platform |
v350 | Maps have been updated to eliminate unnecessary DTC suppression. |
v331 | Synchronized map version across all model years, Implemented Per-Gear Timing compensations, Reshaped boost Targets table for better control at higher RPM (reduced need for SLWG mapping), Revised odd factory Per-Cylinder Injector Pulsewidth tables, Updated Primary OL fuel tables, Revised ignition timing tables based on power and detonation concerns, Many minor adjustments (changed per-cylinder timing compensations slightly, disabled trims based on rear O2 sensor, revised closed loop fuel target at idle, etc.) |
v300 | Now compatible with Launch Control and Flat-Foot Shifting (LC/FFS) features (MT only). For complete details on how to enable and use the LC/FFS functionality, please visit this FAQ. These maps have been created with the newly-released Access Tuner Pro 1.9.0.0. Maps created with this version of Access Tuner software require the latest Accessport firmware (version 1.6.4.0-1189 or higher) be installed. Accessport Manager 2.0 will automatically update the Accessport to the latest firmware version and is available for download on the COBB Tuning Support web page. |
v101 | Lowered boost limits slightly on Stage1 91 and ACN91 maps to be more congruent with targeted boost levels. |
v100 | Original Calibration. Adjusted boost, fuel, ignition, camshaft phasing, and base programming logic to improve driving quality and performance. Revised Closed Loop management for improved driving quality. Smoothed out boost related values, improved boost response at lower RPM. Altered intake camshaft phasing parameters in an effort to improve low and mid-range torque and boost response. Smoothed ignition advance mapping for low to mid RPM response. |
