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.

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.
