Required Accessport Firmware

AP3-POR-015: 1.7.4.2-21848 or Higher

Map Availability:

All maps come pre-installed on the Accessport. Download maps via the COBB Tuning Porsche Map Database

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.
Maps designated with "100 OCT or 105 RON" are for use with 100 octane/105 RON fuel or better.

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.

Peak Increase refers to the point where the output (of hp or torque) is the highest throughout the run
Average HP/TQ refers to the average value present over the entire RPM range
Max Gain is the point with the largest gain over stock

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.
