We've noticed a few simple issues that can cause the flashing process with your car to fail. It is critical to watch out for these problems:

  • A 10-12 amp battery charger is CRITICAL to keep the voltage stable when flashing; if the voltage goes too low, it can cause the flash to fail or brick the module.

  • It is CRUTIAL that you connect the 10-12amp battery charger directory to the battery. DO NOT use the quick jump points.

  • If your key's battery gets low and dies or you walk away, the key can become disconnected from the car and cause the ECU to lose flash mode.

  • Make sure to disable Bluetooth on your cellphone, as the process in which it connects to the stereo can also cause the flash to fail.

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 "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.

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.
