E85 Maps Now Available for Porsche 911 GT3 (997.1)



A recent update for the Porsche platform here at COBB Tuning included significant updates to our Accesstuner for Porsche software to help improve workflow for Certified Protuners utilizing the Accesstuner Pro for Porsche tuning suite. An added bonus to this release is the release of Off The Shelf Maps compatible with E85 fuel for the 997.1 GT3.

Two new maps are now available for the 997.1 911 GT3. Accessports with firmware version or newer. They can also be downloaded from the COBB Website.

Mechanical configuration requirements are the same as existing Stage 1/2 OTS maps, the only change being fuel type.

  • Stage 1 E85 v101.ptm
  • Stage 2 E85 v101.ptm

Additional information can be found on the Map Notes Page.

An example of gains possible using E85 can be seen in the dyno chart below.

    We are not currently working on E85 maps for the 981 cars however it is something we will likely look into in the future.
