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.

Engine Oil Temp Safety

OTS maps have oil temperature safety enabled. Above a temperature of 250°F maximum power will be reduced to reduce the potential for damage caused by excessive oil temperature. Power will be restored once oil temperature falls to a safer level.


Closing Warnings and Precautions:

  • Use of inappropriate calibration/modification combinations will promote engine damage.

  • 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.
