Turbo, Turbo S

  • Stage0 v107
  • Stage1 v107
  • Stage2 v107


2018 GT2 RS

  • Stage0 v106
  • Stage1 v106


Required Accessport Firmware: 

  • AP3-POR-012: 1.7.3.1-16957 or greater





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.


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.

Non Performance Maps

Stage 0 

  • Stock calibration. Factory map that the car was delivered from Porsche with. 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 Turbo 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.
