Boost Control Corrections

Boost Control Corrections


Duty Cycle Correction

Duty Cycle Overall Correction - When the Mode is set to Closed Loop this will be an overall negative correction to the Base Duty Cycle. When the Mode is set to Open Loop this will be an overall positive or negative correction to the Duty Cycle.  This is found on the right hand side of the current page.

Duty Cycle Air Temp Correction - This table allows for correction to the Base Duty for changes in Air Temperature. Typically hotter air requires slightly more duty, and colder air requires slightly less duty. Up to 2D tuning is available.

Duty Cycle Coolant Temp Correction - This table allows for correction to the Base Duty for changes in Coolant Temperature, over a 2D table.

Duty Cycle Gear Correction - This table allows for correction to the Base Duty for changes in Gear Position, over a 2D table.

Duty Cycle TPS Correction - This table allows for correction to the Base Duty for changes in Throttle Position, over a 2D table.

Duty Cycle Flex Fuel Composition Correction - This table allows for correction to the Base Duty for changes in Flex Fuel Composition (ethanol percentage), over a 2D table.

Duty Cycle Generic Correction - When enabled the Duty Cycle Generic Correction tab will become available. This table allows for any ECU channel to be used for boost control duty correction mapping. Up to 3D mapping is available.

Target Pressure Correction

Target Pressure Corrections are only available when the Boost Control Mode is set to Closed Loop.

Target Pressure Overall Correction - This is an overall negative correction to the Target Pressure. This is found on the right hand side of the current page.

Target Pressure Air Temp Correction - This table allows for a Target Boost correction based on the Air Temperature. This is typically used to add an added level of engine safety by allowing the Target Boost to be lowered for excessively hot intake air temperatures if desired. This is a 2D table.

Target Pressure Coolant Temp Correction - This table allows for a Target Boost correction based on the Coolant Temperature. This is typically used to add an added level of engine safety by allowing the Target Boost to be lowered for excessively hot Coolant Temperatures or for cold engines if desired. This is a 2D table.

Target Pressure Gear Correction - This table allows for a Target Boost correction based on the Gear Position. This is typically used for lowering the Target Boost in the lower gears to assist with traction.. This is a 2D table.

Target Pressure TPS Correction - This table allows for a Target Boost correction based on the Throttle Position.  This is typically used to lower the Target Boost at smaller throttle openings to give the engine a more linear power response to throttle opening. This is a 2D table.

Target Pressure Flex Fuel Composition Correction - This table allows for a Target Boost correction based on the Ethanol%. This is typically used to increase the Target Boost when there is a higher ethanol percentage in the system for added performance. This is a 2D table.

Target Pressure Generic Correction - When enabled the Target Pressure Generic Correction tab will become available. This table allows for a Generic Correction to the Duty Output based on any Custom conditions that the tuner requires. Up to 3D mapping is available.
