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 "ACN91 OCT or 93 RON" are for use with 91 octane fuel found in Arizona, California, and Nevada, Canadian 94 Octane and 94 Octane with 0% ethanol, 93 RON fuel or better.

  • 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. 

 




Dyno results and gains are from first party testing on external dyno and blended 93 octane due to lack of vehicle and fuel availability to COBB for in house testing.

Peak Gains are reported as the absolute maximum value (HP and TQ) between the highest points of two plots.
Max. Gains are reported as the maximum TQ or HP gain at any point across engine speed range.

Non-Performance Maps

Stage 0

  • Stock calibration. Factory map. Does Not Uninstall Accessport.





Closing Warnings and Precautions:

  • Use of inappropriate calibration/modification combinations will promote engine damage.

  • Seek the help of a professional COBB Protuner should your Porsche fall outside of OTS map requirements.

  • Top Tier gasoline should be used where available. Use of lower quality fuels can result in catastrophic engine damage.

  • For track events, we recommend adding at least 2 gallons of 100 octane fuel to battle high track temperatures.
