Required Accessport Firmware

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 102 RON" are for use with 100 octane/102 RON fuel or better.
