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.

Monitoring Boost Levels: 

The best way to determine if you are hitting target boost is to watch the TD Boost Error parameter. This parameter is your target boost (including altitude and temperature compensations) minus your actual boost (negative values mean you are over the target by the amount while positive values mean you are under). Ideally you want this value to be between 0 and 1.0 at wide open throttle (WOT), but -1.0 to 1.0 is acceptable assuming that you don’t have any significant knock corrections. Overboosting is more likely to occur in higher gears and with colder outside temperatures, so be sure to verify boost levels during these conditions.

High Altitude: 

A quick note for those of you that live at higher altitudes. It is common for turbocharged cars at higher altitudes to run less boost pressure due to lower air pressure and air density. Your turbocharger has to work harder to compress a less dense air mass compared to the same turbocharger at sea level. This must be factored in when determining if your turbocharger is running the proper amount of boost pressure and not being pushed beyond its efficiency range. 

There are barometric compensations within the factory ECU that lower boost targets as you climb in altitude in an effort to keep the turbocharger in its optimal range.The COBB performance maps utilize these compensations and therefore, it is perfectly normal for the final boost target to be lower than what is listed for your map.

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.
