Map Notes for VA WRX (USDM)
Supported Vehicles:
Model year 2015-2021 WRX 6MT, CVT USDM 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 "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.
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.
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
