<strong>Map</strong> <strong>Notes</strong> <strong>for</strong><strong>2007</strong> <strong>STI</strong>Supported Vehicles: USDM <strong>2007</strong> <strong>STI</strong><strong>Map</strong> Revision: Stage1 91 v300 Stage2 91 v300 Stage1 93 v300 Stage2 93 v300 Stage1 ACN91 v300 Stage2 ACN91 v300<strong>Map</strong> Availability: Download from the COBB <strong>Tuning</strong> Subaru STi OTS <strong>Map</strong> Database.Required AccessPORT Firmware: 1.6.4.0 or greaterHardware Requirements: Stage1 - Otherwise stock vehicle with the following modifications*: Intake Requirements: Stock airbox or COBB <strong>Tuning</strong> SF Intake Exhaust requirements: Stock exhaust or upgraded cat-back exhaustHardware Requirements: Stage2 - Otherwise stock vehicle with the following modifications*: Intake Requirements: Stock airbox or COBB <strong>Tuning</strong> SF Intake Exhaust requirements: Upgraded turbo-back exhaust*** The addition of any other hardware may make the vehicle per<strong>for</strong>m poorly.* No other intakes, turbochargers, or fuel injectors are certified as compatible with these maps. *** The Stage2 maps were developed using a COBB <strong>Tuning</strong> turbo-back exhaust system with a high-flow catalyticconverter. An equivalent turbo-back exhaust system could also be used. If a lesser flowing turbo-back exhaustsystem is used then boost targets may not be achievable. These maps are NOT designed to be used with anaftermarket race downpipe that does not have a catalytic converter (i.e. catless). Doing so greatly increases thechance <strong>for</strong> boost spikes and boost creep.Additional <strong>Notes</strong>:Additional modifications such as an upgraded panel filter, lightweight crank pulley, aftermarket up-pipe, orrecirculating by-pass valve are still within the acceptable modifications <strong>for</strong> this calibration. If any knock ordetonation is present even when using the appropriate fuel, try reflashing a map that is intended <strong>for</strong> a loweroctane fuel. If your modifications do not match the hardware requirements listed above, you can have a customAccessPORT map made at one of the COBB <strong>Tuning</strong> retail and service centers or one of the many professionalSubaru Pro-Tuners and e-Tuners.2311 W Rundberg Ln.

Fuel Requirements:Each map lists the minimum required octane. A higher octane fuel can be used safely on a mapdesigned <strong>for</strong> lower octane. DO NOT use maps designed <strong>for</strong> higher octane with lower octanefuels. Top Tier gasoline should be used where available.Ca<strong>Map</strong>s designated with “93” are <strong>for</strong> use with 93 and 94 octane fuel or better.<strong>Map</strong>s designated with “91” are <strong>for</strong> use with 91 and 92 octane fuel or better.<strong>Map</strong>s designated with “ACN91” are <strong>for</strong> use with 91 octane fuel found inArizona, Cali<strong>for</strong>nia, and Nevada or better.Typical Stage1 and Stage2 vs. Stock Power:Stage1 ACN91 - +10% HP / +15% TQStage1 91 - +10% HP / +15% TQStage1 93 - +13% HP / +17% TQStage2 ACN91 - +18% HP / +33% TQStage2 91 - +18% HP / +33% TQStage2 93 - +19% HP / +35% TQResults may vary. Power as tested on <strong>2007</strong> STi vehicle using these identical calibrations. Generallyspeaking, the 91 and ACN91 calibrations run slightly lower boost, have a richer fuel curve, and a less aggressiveignition advance map to help compensate <strong>for</strong> 91 octane fuel; Arizona, Cali<strong>for</strong>nia, and Nevada 91 octane fuel;and/or less than ideal atmospheric conditions. The maps designed <strong>for</strong> 93 octane are the most aggressive.2311 W Rundberg Ln. Suite 500 Austin, TX 78758 | Phone: 866.922.3059 | Fax: 512.997.6400 | www.cobbtuning.com

All AccessPORTs must first be updated be<strong>for</strong>e using maps created with this latest AccessTUNERversion. AccessPORT Manager 2.0 will automatically update the AccessPORT to the latest firmware version andis available <strong>for</strong> download on the COBB <strong>Tuning</strong> Support web page.1.04 - Revised calibration <strong>for</strong> more stable ignition timing and optimal per<strong>for</strong>mance. Early transitions to open loopfueling under full throttle <strong>for</strong> better per<strong>for</strong>mance. Modified throttle mapping to smooth out throttle transitions.1.03 - Several calibration revisions were made to the throttle-by-wire system in order to address the followingreported issues:On/Off throttle transitions, the car is slow to accelerate then jumps once you get close to WOT.Downhill throttle hesitations, the car's RPM fluctuations when trying to steady state coast or deceleratedownhill.Dead pedal feel at partial throttle.Hesitations during throttle transitions.1.01 - This calibration has been updated to the latest version. The throttle-by-wire settings were changed topromote smoother throttle transitions. The closed loop control settings were revised to allow <strong>for</strong> a smoothertransition from part throttle to WOT. MIL codes made present by the installation of the MIL Eliminator mechanicalCEL fix have been defeated (see below).1.00 - Original Calibration. Tuned AVCS, Boost, Fuel, Ignition, closed loop control, Dynamic Advance, ThrottleDuty Cycles, and base programming logic to improve drive-ability. Revised Closed Loop management (BASEMAP CHANGE). Revised Boost Control parameters. Smoothed out boost related values, improved boostresponse at lower RPMs. Revised AVCS <strong>Map</strong>ping. Altered intake cam timing parameters in an ef<strong>for</strong>t to improvelow and mid-range torque and boost response. Modified high RPM timing and dynamic advance parameters toallow <strong>for</strong> improved ignition advance learning when using improved octane. Modified Primary Fuel & PrimaryIgnition tables to account <strong>for</strong> the effects of AVCS tuning. Further tuned Dynamic Advance table to promotesmooth transitional (low RPM to high RPM) acceleration. Raised speed limiter. Moved Speed Limits to 186 mph.Increased boost cut to ~21psi at sea level. This calibration has been updated to the latest AccessTUNER file<strong>for</strong>mat, (<strong>for</strong>merly ProTUNER).2311 W Rundberg Ln.
