COBB Custom ECU Features


Towing

COBB's staged performance maps are designed for performance driving and have not been optimized for use when towing.  COBB recommends flashing the Performance Tow or Stage0 ECU calibrations and using the truck's 'Tow' drive mode.




Map Availability: 





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 "87 OCT or 91 RON" are for use with 87 to 90 octane (91 to 94 RON) fuel or better. 
  • Maps designated with "91 OCT or 95 RON" are for use with 91 and 92 octane (95 to 97 RON) fuel or better. It is also recommended to use a 91 OCT or 95RON map when running 94 with 0% ethanol.
  • Maps designated with "93 OCT or 98 RON" are for use with 93 and above octane (98+ RON) fuel or better.

Stage1 91 Oct. or 95 RON+9.10% HP/ +14.93% TQ

+18.17% HP/ +18.17% TQ


Generally speaking, 91 octane calibrations have less aggressive ignition advance to help compensate for lower octane fuel blends. The maps designed for 93 octane are the most aggressive.

Stage1

  • Intake Requirements: Stock airbox with stock/COBB air filter
    • Optional: COBB SF Intake  
  • Intercooler requirements: Stock intercooler
  • Exhaust requirements: Stock exhaust
  • Boost: Dynamic based upon atmospheric conditions, fuel quality, gear, RPM, and drivetrain
    • Fuel Octane 87 (91 RON) Minimum Up to ~16psi +/- 2psi tapering to ~9psi by redline
    • Fuel Octane 91 (95 RON) Minimum Up to ~19psi +/- 2psi tapering to ~13psi by redline
    • Fuel Octane 93 (98 RON) Minimum Up to ~19psi +/- 2psi tapering to ~13psi by redline


Unless otherwise noted the COBB Dynamic Pedal Control is set to 2 for all maps

Maximum gains are measured as the largest gain at any single point between the two plots.

Generally speaking, 91 octane calibrations have a less aggressive ignition advance map to help compensate for lower octane fuel blends. The maps designed for 93 octane are the most aggressive.

Stage2

  • Intake Requirements: Stock airbox with stock/COBB air filter
    • Optional: COBB SF Intake  
  • Intercooler requirements: COBB FMIC
  • Exhaust requirements: Stock exhaust
  • Boost: Dynamic based upon atmospheric conditions, fuel quality, gear, RPM, and drivetrain
    • Fuel Octane 87 (91 RON) Minimum Up to ~16psi +/- 2psi tapering to ~9psi by redline
    • Fuel Octane 91 (95 RON) Minimum Up to ~19.5psi +/- 2psi tapering to ~14psi by redline
    • Fuel Octane 93 (98 RON) Minimum Up to ~19.5psi +/- 2psi tapering to ~14psi by redline


Unless otherwise noted, the COBB Dynamic Pedal Control is set to 2 for all maps

C.A.R.B. Note

The above Stage1 and Stage2 calibrations are legal for use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it and the parts have a California Air Resources Board (CARB) Executive Order (EO) number: 

Maximum gains are measured as the largest gain at any single point between the two plots.

Power output on Performance Tow calibrations will change with vehicle drive mode, with Sport drive mode producing more than Normal and Tow drive modes.  Power and torque in Normal and Tow drive modes is shown in the dotted red and blue lines, respectively.  Power and torque in Sport drive mode is shown in the solid red and blue lines, respectively.  Stock output (regardless of vehicle drive mode) is shown by the dashed lines.  Peak and maximum gains shown here represent the differences between the Performance Tow map in Sport mode vs. stock.

Generally speaking, 91 octane calibrations have a less aggressive ignition advance map to help compensate for lower octane fuel blends. The maps designed for 93 octane are the most aggressive.

Performance Tow

  • Intake Requirements: Stock airbox with stock/COBB air filter
    • Optional: COBB SF Intake  
  • Intercooler requirements: Stock intercooler

Notes on Knock Octane Modifier (KOM):   

  • Knock Octane Modifier (KOM) is a learned variable that will change dependent mainly on knock corrections over time.  KOM can dictate how much load, boost, ignition timing, etc... the truck will run.  The lower the KOM the less the power output.  Ideally this value should be at +1.0 but it can change depending on conditions other than knock.  
  • Knock Octane Modifier (KOM) will be limited to less than or equal to 0 while Engine Coolant Temperature is below 130*F (54.5*C) on COBB OTS maps.  By 135*F (57*C), KOM will return to the retained learned value if it is greater than 0.  It is common to see a KOM of 0 when the vehicle is warming up.  Limiting Knock Octane Modifier during warm up is done to prevent unnecessary strain before the engine has reached a reasonable temperature.   
  • Knock Octane Modifier (KOM) will be limited to -1.0 while Engine Coolant Temperature is above 250*F (121*C) on COBB OTS maps.  This is to prevent heavy load in the case the vehicle begins to overheat due to a mechanical failure.   
  • Knock Octane Modifier and Coolant Temperature are both parameters the Accessport can monitor. 


Closing Warnings and Precautions: 

  • Use of inappropriate calibration/modification combinations will promote engine damage.
  • COBB OTS mapping is NOT designed to be used with upgraded aftermarket boost actuators or solenoids. Doing so may result in much higher than desired boost and potential engine damage. Seek the help of a COBB Accesstuner Professional should your vehicle fall outside of OTS configurations.
  • Top Tier gasoline should be used where available. Use of lower quality fuels can result in catastrophic engine damage.
