There is a new element to the ECU flashing process for vehicles supported by these three Accessports.  Just as COBB did over 10 years ago with it’s first ECU flashes, we will be bringing ECUs in-house in order to unlock them before an Accessport can be installed.  This means the process for installing an Accessport on your 718 or 991.2 vehicles will be a bit more involved than in years past.  Not to fret, we have a system in place to ensure ECUs are shipped and returned in a timely manner.  Customers will be updated at each step along the way, from the initial purchase to receiving the unlocked ECU and Accessport.

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.
