Supported Vehicles:

  • USDM 2007-2009 Legacy GT AT/MT

  • USDM 2007-2009 Legacy GT SpecB MT

  • USDM 2007-2009 Outback XT AT/MT


Map Revision:



2007-09 Legacy GT, Spec B, Outback XT

  • Stage0 v400
  • Stage1 v400






Map Availability: 

Required Accessport Firmware: 

  • V3: 1.7.4.0-17431 or greater



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.

  • Maps designated with "93" are for use with 93 and 94octane fuel or better.
  • Maps designated with "91" are for use with 91 and 92 octane fuel or better.
  • Maps designated with ACN 91 are for use with 91 octane fuel or better fuel found in Arizona, California and Nevada in addition to Canada.

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" octane version 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. 
 

If you are unfamiliar with how to datalog using the Accessport or what to look for, you can find a guide on our website here. 
 

If any knock or detonation is present even when using the appropriate fuel, try reflashing a map that is intended for a lower octane fuel.

C.A.R.B Note

The above Stage1 calibration is legal for use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number:

Peak Gains*

Stage1 ACN91

+2% HP / +4% TQ over stock

Stage1 91+2% HP / +5% TQ over stock
Stage1 93+3% HP / +8% TQ over stock


Stage1

  • Intake Requirements: Stock airbox and stock filter
  • Exhaust Requirements: Stock exhaust
  • Boost Targets: 
    • ACN91: ~15psi peak boost pressure tapering down to ~12.0psi by the 6700RPM redline, +/- 0.8 psi
    • 91 Octane 95 RON Minimum: ~15psi peak boost pressure tapering down to ~12.0psi by the 6700RPM redline, +/- 0.8 psi
    • 93 Octane 98 RON Minimum:  ~15psi peak boost pressure tapering down to ~12.0psi by the 6700RPM redline, +/- 0.8 psi




*Peak gains are measured as the difference between the highest points of the two plots. 

*Largest gains are measured as the largest gain at any single point between the two plots. 

Results may vary. Power as tested on an 2007-2009 LGT and 2007-2009 OXT vehicles using these identical calibrations. Generally speaking, the 91 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 octane are the most aggressive.

All Stage1 performance maps include a “HWG” and “LWG”:

    • 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).  



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:
v400Maps updated to eliminate unnecessary DTC Supression or updated versions for parity with other maps/vehicles within the platform
v350Maps have been updated to eliminate unnecessary DTC suppression or to reflect an updated code base
v301Updated calibration to help prevent turbo over boost conditions and to increase the window for knock feedback activity. This release also corrects an issue with mismatched mapping/vehicle identification for the 2007 LGT AT vehicle.
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 AccessTUNER Pro 1.9.0.0. Maps created with this version of AccessTUNER software require the latest AccessPORT firmware (version 1.6.4.0-1189 or greater) be installed. All AccessPORTs must first be updated before using maps created with this latest AccessTUNER version. 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.

v103The calibration has been updated to eliminate the over boost conditions when the car is driven under heavy loads or held at wide open throttle (WOT) from too low of an RPM. Turbo controls were also enhanced to help prevent an over boost condition.
v101The calibration has been updated to allow the vehicle to achieve the boost targets when driving in colder ambient temperatures. Table changes have been made to limit the fuel cut function that occurs when the engine RPM hit the Rev Limiter.
v100Original Mapping. Adjusted Fuel, Ignition Advance, Boost Control, Camshaft Phasing (AVCS), closed loop control, knock corrections, throttle mapping, and base programming logic. Revised Closed Loop management (REFLASH MAP CHANGE) for improved driving quality. Smoothed out boost related values and improved boost response at lower RPM. Modified the fuel metering calculations for more accurate fueling calculations for the specified fuel.
