Supported Vehicles:

  • Some model year 2015-2021 WRX 6MT (North American, ADM Spec) 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.

  • Maps designated with "93" are for use with 93 and 94 octane/98 RON fuel or better.
  • Maps designated with "91" are for use with 91 and 92 octane/95 RON fuel or better. (Recommended for vehicles in Canada running 94 octane or higher)

...

 

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.

Stage1

  • Intake Requirements: Stock airbox and stock air filter

  • Exhaust Requirements: Stock

  • Boost Targets:

    • 91 Octane 95 RON Minimum: ~19.0psi peak boost pressure tapering down as you approach the 6900RPM redline, +/- 1.5psi.

    • 93 Octane 98 RON Minimum: ~19.0psi peak boost pressure tapering down as you approach the 6900RPM redline, +/- 1.5psi.

Stage1+BigSF

  • Intake Requirements: COBB Tuning BigSF Intake and Airbox System 745110 

  • Exhaust Requirements: Stock

  • Boost Targets

    • 91 Octane 95 RON Minimum: ~19.0psi peak boost pressure tapering down as you approach the 6900RPM redline, +/- 1.5psi.

    • 93 Octane 98 RON Minimum: ~19.0psi peak boost pressure tapering down as you approach the 6900RPM redline, +/- 1.5psi.

...

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

Results may vary. Power as tested using these identical calibrations. Generally speaking, the 91 octane calibration has a richer fuel curve and a less aggressive ignition advance map to help compensate for 91 octane fuel and/or less than ideal atmospheric conditions. The map designed for 93 octane is the most aggressive.

  • Maps designated with "91 OCT or 95 RON " are for use with 91 and 92 octane/95 RON fuel or better.

  • Maps designated with "93 OCT or 98 RON" are for use with 93 octane/98 RON fuel or better.

    • 94 octane with 0% Ethanol should run the ACN91 Map.

 

Note

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.

Info

Peak Increase compares the highest value present for each run regardless of RPM

Max HP/TQ is the largest difference when comparing stock vs tuned at a single RPM point

Average HP/TQ refers to the average value present over the entire RPM range
