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

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

*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 2019 GLI DSG 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.
