Hardware Requirements:

Stage2 requires an exhaust system in order to be used. Intercoolers are recommended on any stage to combat high intake air temps on the Porsche.

Stage3 1000 requires an exhaust system, Cobb1000cc fuel injectors(Discontinued), and upgraded intercoolers.

Stage3 1300 requires an exhaust system, Cobb1300cc fuel injectors(Discontinued), and upgraded intercoolers.

*Stage 3 Maps are available here via Cobb Tuning's Website.  
  • NOTE: Stock and OTS maps are not compatible with iPE Exhaust systems.

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 "100" are for use with 100 octane/104 RON fuel or better.
  • 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.
  • Maps designated with "ACN91" are for use with 91 octane fuel found in Arizona, California, and Nevada or better.
  • Maps designated with "E85" are for use with 85% Ethanol, 15% Gasoline fuel only.


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

    Valet Mode 

    • Rev limiter set to 4000 RPM. Not for use with Stage3. Boost lowered to half of normal.

    Anti-Theft Mode 

    • This map will not allow the vehicle to start.

    Stage 0 

    • Stock calibration. No changes made at all. 



    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 when 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.

    • If using E85 it is your responsibility to ensure you are getting the proper mixture from your station. Many stations change to an E70 blend in the winter.

    Revision Notes:

    Map VersionNotes:
    v104

    Map description fixes. 

    V103:
    v103

    Updated maps to add factory fuel PID oscillation issue to all Stage3 B742 maps as well as Stage1 & Stage2 B742 maps that were fixed in V102.  All 997.1 Turbo maps updated to V103 for conformity, but only B742 Stage3 maps have been modified.

             V102:

    v102

    Updated maps to correct a factory fuel PID oscillation issue unique to B742 ROMS.  All 997.1 Turbo maps updated to v102 for conformity, but B721, B730, B740, B821, and B830 maps are unchanged from V101.

           V101:

    v101

    Improved map stability and map maintenance update for future feature support. Initial launch of Stage3 Maps located on our website.  www.COBBTuning.com

     

    V100:
    v100

     Adjusted load correction, load and torque limits, raised vehicle rev limits, raised vehicle speed limits, brake boosting enabled for 2 seconds. Also increased boost in both normal and sport modes. Made fueling changes as well as timing changes and raised the timer for sport mode to 30 seconds.


    NoteB721, B730, B740, B742 are the operating system for the 997.1 Turbo, B821 and B830 are the operating system for the 997.1 GT2.  These can be found as the first 4 values of your ROM ID.  The ROM ID can be found on the AP under Help → About Accessport  → Installed Vehicle.  Or in Accessport Manager under the AP Info Tab.
