General

• Torque Reduction: Master enable/disable for Torque Reduction via cylinder fuel cut.
• Torque Intervention: Enables check between throttle related load and airflow related load calculations.
• Fuel Cut Torque Ratio vs. Requestor: If the Torque Ratio Request is below this value then cylinder fuel cut will be used instead of spark or ETC torque reduction methods. Set to 0.0 to disable cylinder fuel cut.
• Spark Torque Ratio Limit vs. Requestor: Torque Reduction via spark retard will not go below this Torque Ratio, set to 1.0 to disable spark retard torque reduction.

Engine Torque

• Indicated Engine Torque vs. RPM vs. Load: The calibration for the amount of torque(excluding friction and accessory losses) the engine is making for a given RPM and Load.
• Indicated Engine Torque vs. RPM vs. Torque:
• Engine Friction Torque vs. RPM vs. ECT: This is the amount of engine torque lost to friction.
• Engine Inertia Torque:

ETC Torque Management

• ETC Tip-In Torque Rate Max vs. N/V vs. Slip Ratio: This value sets the ETC Tip-in Torque Rate Max value in relation to N/V and the current transmission slip ratio.
• ETC Tip-In Torque Rate Mult vs. Pedal Position vs. VSS: This value multiplies the ETC Tip-in Torque Rate Max value in relation to pedal position and vehicle speed. Higher values raise the tip-in torque limit.
• ETC Torque Reduction RPM vs. Requestor: Below this RPM the ETC may be used for torque reduction for the various modes requested.
• ETC Torque Max vs. RPM: The maximum torque allowed by the ETC in relation to RPM, often used by automatic transmission to limit torque in Park/Neutral.
• ETC Clip Torque vs. Requestor: Amount of clip torque based on the current ETC torque mode.

Oil Overtemp

• Oil Overtemp Disable ECT: Oil Overtemp disable ECT limit.
• Oil Overtemp Enable ECT: Oil Overtemp enable ECT limit.
• Oil Overtemp B Disable ECT: Oil Overtemp disable ECT limit.
• Oil Overtemp B Enable ECT: Oil Overtemp enable ECT limit.
• Oil Overtemp Enable Load: Oil Overtemp enable Load limit.
• Oil Overtemp Enable RPM: Oil Overtemp enable RPM limit.
• Oil Overtemp Enable TPS: Oil Overtemp enable TPS limit.
• Oil Overtemp TqRed Enable OilTemp: Oil Overtemp enable Oil Temp limit.
• Oil Overtemp TqRed Disable OilTemp: Oil Overtemp disable Oil Temp limit.
• Oil Overtemp Torque Ratio vs. ECT: Commanded torque ratio for Oil Overtemp Protection in realtion to ECT.
• Oil Overtemp Torque Ratio vs. RPM: Commanded torque ratio for Oil Overtemp Protection in realtion to RPM.

Turbocharger

• Turbo Logic: Selects if the turbocharger login is executed.
• Turbo Wastegate: Selects if the electronic wastegate hardware is fitted.
• Boost Pressure Sensor: Selects if the boost pressure sensor is fitted.

Wastegate Control

• Turbo Desired Boost: The desired boost pressure.
• Turbo Wastegate Duty Cycle: The commanded openloop wastegate duty cycle, used as the basse for closed loop boost control.
• Turbo Max DC: Wastegate duty cycle is limited to this value.
• Turbo Boost Mult vs. ECT: This value multiplies the Desired Boost and Wastegate Duty Cycle values in relation to engine coolant temperature.
• Turbo Boost Mult vs. Baro: This value multiplies the Desired Boost and Wastegate Duty Cycle values in relation to barometric pressure.
• Turbo Boost Mult vs. TPS: This value multiplies the Desired Boost and Wastegate Duty Cycle values in relation to throttle position.

Boost Threshold

• Turbo On/Off Boost Thresh: This value is the TPS threshold for on/off boost control, when off boost, closed loop boost control is generally disabled.
• Turbo On/Off Boost Hyst: Hysteresis value for on/off boost test.

Proportional Gain

• Turbo Proportional Gain: This is the proportional gain for boost control in relation to the boost error. It is important to have 0 gain at 0 boost error.
• Turbo Proportional Gain On Boost Min: Proportional Gain minimum when on boost.
• Turbo Proportional Gain On Boost Max: Proportional Gain maximum when on boost.
• Turbo Proportional Gain Off Boost Min: Proportional Gain minimum when off boost.
• Turbo Proportional Gain Off Boost Max: Proportional Gain maximum when off boost.

Integral Gain

• Turbo Integral Gain: Integral Gain used for closed loop boost control.
• Turbo Integral Gain On Boost Min: Integral Gain minimum when on boost.
• Turbo Integral Gain On Boost Max: Integral Gain maximum when on boost.
• Turbo Integral Gain Off Boost Min: Integral Gain minimum when off boost.
• Turbo Integral Gain Off Boost Max: Integral Gain maximum when off boost.

Under Boost

• Turbo Underboost Error Thresh: If boost error is greater than this an underboost condition is set.
• Turbo Underboost DC: If an underboost condition is set the wastegate duty cycle is fixed at this value.

Over Boost

• Turbo Overboost Error Thresh: If boost error is less than this an overboost condition is set.
• Turbo Overboost DC: If an overboost condition is set the wastegate duty cycle is fixed at this value.

Turbo Test

• Turbo Test Thresh: If Turbo Test Boost or Turbo Test DC is greater than this then they are used, otherwise they are ignored.
• Turbo Test Boost: If this value is greater than Turbo Test Thresh, then desired boost is fixed a this value.
• Turbo Test DC: If this value is greater than Turbo Test Thresh, then wastegate duty cycle is fixed at this value.

PWM Output

• Wastegate Period: Defines the PWM period for the wastegate control output.

Shift torque Limit

• Turbo Shift Torque Limit 1-2: Torque limit for 1-2 Shift on boost.
• Turbo Shift Torque Limit 2-3: Torque limit for 2-3 Shift on boost.
• Turbo Shift Torque Limit 3-4: Torque limit for 3-4 Shift on boost.
