1 COBB TUNING AccessPORT Calibration Notes for 2012 Subaru WRX STI Power Output: Stage1+Intake 93 v % HP / +37.3% lb-ft over stock. Power Output: Stage2+Intake 93 v % HP / +46.7% lb-ft over stock. Results may vary. Gains stated by peak numbers. Power as tested on 2011 STI Sedan using identical calibrations.

2 Hardware Requirements: Stage1+Intake - Otherwise stock vehicle with one of the supported intakes listed below. The addition of any other hardware may make the vehicle perform poorly. Hardware Requirements: Stage2+Intake - Otherwise stock vehicle with a one of the supported intakes listed below., tested with a Cobb Tuning turbo-back exhaust system with at least one high-flow catalytic converter. An equivalent turbo-back exhaust system could be used. If the turbo-back exhaust system relieves back-pressure to an excessive point boost creep is possible. If a lesser flowing turbo-back exhaust system is used then boost targets may not be achievable. The addition of any other hardware may make the vehicle perform poorly. Supported Intake Systems: COBB Tuning SF Intake and Airbox (PN B*); maps designated by +SF AEM Cold Air Intake (PN ); maps designated by +AEM Fuel Requirement: This varies by calibration, 93 or 94 octane, 91 or 92 octane, or if you live in Arizona, California, or Nevada, we have a specific calibration for the 91 octane fuel in your state, this calibration is called the Stage1 ACN91 v310. If detonation is present, you should switch to a calibration developed for a lesser quality fuel or your should add a quality octane boost to your fuel. Additional Notes: Additional modifications such as an under drive pulley or recirculating BOV are still within the acceptable modifications for this calibration. YOU MUST USE THE AFOREMENTIONED COBB TUNING SF INTAKE OR AEM COLD AIR INTAKE WITH THE RESPECTIVE +SF OR +AEM MAPPING, ALL OTHER AFTER MARKET INTAKES ARE NOT CERTIFIED AS COMPATIBLE WITH THESE CALIBRATIONS. If any knock or detonation is present even when using the appropriate fuel, try using octane booster or reflashing a map that is intended for a lower octane. Revision Notes: 3.00 and greater These maps have been created with the newly-released AccessTUNER Pro Maps created with this version of AccessTUNER software require the latest AccessPORT firmware (version 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. Map Notes: 3.10 Minor revisions for 2012 model year. Includes minor vehicle usability improvements such as an increase to the Cruise Control Maximum MPH limit 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 Initial release of mapping calibrated to support the COBB Tuning SF Intake and AEM Cold Air Cold Air Intake. 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

3 values,improved boost response at lower RPM. Altered intake and exhaust camshaft phasing parameters in an effort to improve low and midrange torque and boost response. Smoothed ignition advance mapping for low to mid RPM response. Simplified ignition timing strategy to remove undesirable additive/jumping timing behavior. Incorporates boost select feature to enable driver-activated secondary boost target via SI-Drive mode selector switch (S mode is lower boost, S# mode is higher boost). Compatible with AccessPORT Latest Calibration Revision: 3.10 Calibration and Map Notes Updated: 01/17/12 Boost Targets: The boost targets for each map can be seen above in the boost graphs or read below in the various map descriptions.

4 Performance Maps: Stage1+Intake Economy Mode v310 - Intended for 2012 Subaru Impreza WRX STI vehicles with COBB Tuning SF Intake or AEM Cold Air Intake. Requires a minimum of 91 octane petrol. Low boost and lower rev limiter (5400 RPM) for optimal fuel savings. Not a performance calibration and not recommended for aggressive driving. THIS MAP IS NOT INTENDED FOR SPIRITED DRIVING. Stage1+Intake ACN91 v310 Boost Select - Intended for 2012 Subaru Impreza WRX STI vehicles with COBB Tuning SF Intake or AEM Cold Air Intake with a stock or cat-back exhaust running Arizona, California or Nevada 91 octane petrol. Boost Targets: ~17.5psi (S Sharp) or 14.5 psi (S) peak boost pressure tapering down to ~13.0 psi by the 6700 RPM redline, +/- 1.0 psi. Stage1+Intake 91 v310 Boost Select - Intended for 2012 Subaru Impreza WRX STI vehicles with COBB Tuning SF Intake or AEM Cold Air Intake with a stock or cat-back exhaust running 91 or 92 octane petrol. Boost Targets: ~17.5psi (S Sharp) or 14.5 psi (S) peak boost pressure tapering down to ~13.0 psi by the 6700 RPM redline, +/- 1.0 psi. Stage1+Intake 93 v310 Boost Select - Intended for 2012 Subaru Impreza WRX STI vehicles with COBB Tuning SF Intake or AEM Cold Air Intake with a stock or cat-back exhaust running 93 or 94 octane petrol. Boost Targets: ~18psi (S Sharp) or 15 psi (S) peak boost pressure tapering down to ~13.5 psi by the 6700 RPM redline, +/- 1.0 psi. Stage2+Intake Economy Mode v310 - Intended for 2012 Subaru Impreza WRX STi with STOCK FUEL INJECTORS and AEM Cold Air Intake. Requires a minimum of 91 octane fuel. Low boost, increased ignition timing, leaner fuel curve, and lower Rev Limiter for optimal fuel savings. Not a performance calibration and not recommended for aggressive driving. THIS MAP IS NOT INTENDED FOR SPIRITED DRIVING. Rev Limit lowered to 5800 RPM. Stage2+Intake ACN91 v310 Boost Select - Intended for 2012 Subaru Impreza WRX STI vehicles with AEM Cold Air Cold Air Intake System, and a turbo-back exhaust system with high-flow catalytic converter running Arizona, California, or Nevada 91 octane petrol. Boost Targets: ~18.2psi (S#) or 15.5 psi (S) peak boost pressure tapering down to ~15psi by the 7000 RPM redline, +/- 1.0psi. Non-Performance Maps: Stage1+Intake Economy Mode v310 - Intended for 2012 Subaru Impreza WRX STI vehicles with COBB Tuning SF Intake or AEM Cold Air Intake. Requires a minimum of 91 octane petrol. Low boost and lower rev limiter (5400 RPM) for optimal fuel savings. Not a performance calibration and not recommended for aggressive driving. THIS MAP IS NOT INTENDED FOR SPIRITED DRIVING. Stage2+Intake Economy Mode v310 - Intended for 2012 Subaru Impreza WRX STi with STOCK FUEL INJECTORS and AEM Cold Air Intake. Requires a minimum of 91 octane fuel. Low boost, increased ignition timing, leaner fuel curve, and lower Rev Limiter for optimal fuel savings. Not a performance calibration and not recommended for aggressive driving. THIS MAP IS NOT INTENDED FOR SPIRITED DRIVING. Rev Limit lowered to 5800 RPM. * All Stage1 performance maps now include a HWG and LWG version: HWG: Higher wastegate duty cycles (HWG) for use when regular calibration produces lower than targeted boost. LWG: Lower wastegate duty cycle (LWG) for use when regular calibration produces higher than targeted boost.

5 * Graphs may not be those of the 91 or ACN91 maps. Generally speaking, the 91 and ACN91 calibrations run slightly lower boost, have a richer fuel curve, and the ignition advance map is less aggressive to help compensate for the normal 91 or specific Arizona, California, or Nevada 91 octane fuel & atmospheric conditions (i.e. less than ideal). The maps designed for 93 octane are the most aggressive.
