Curious, when is open and closed loop operation?
Lambda Control
The operation of the closed loop lambda function is defined by the settings in Lambda Constants of the System Editor. The configuration variable is used to enable the closed loop function and also allows selection for feedback to be from either the lambda 1 or 2 inputs or both if the bank configuration option is checked. The following section describes the functions of each of the lambda control varaibles.

The configuration variable is used to enable the closed loop function and also allows selection for feedback to be from either the lambda 1 or 2 inputs or both if the bank configuration option is checked. The following section describes the functions of each of the lambda control varaibles.
- Lambda Configuration - Enable the various lambda control options.
- PID Throttle limit - Sets the minimum throttle angle required to activate closed loop control.
- PID RPM limit - Sets the minimum engine rpm required to activate closed loop contrrol.
- Air Temp limit - Sets the minimum air temp required to activate closed loop control.
- Water Temp limit -Sets the minimum water temp required to activate closed loop control.
- Lean Correction limit - Sets the maximum percent the mixture can be leaned out under closed loop control.
- Rich Correction limit - Sets the maximum percent the mixture can be richened under closed loop control.
- PID Active temp - Sets the minimum sensor resistance required to enable closed loop control. This is only used in temperature compensation mode and must be set to 255 when using an NGK sensor.
- Lambda failed high - Sets the lambda sensor failed high value that disables closed loop control.
- Lambda failed low - Sets the lambda sensor failed low value that disables closed loop control.
- Heater disable temp - Sets the sensor resistance at which the heater circuit is disabled. This is only used in temperature compensation mode and must be set to zero when using an NGK sensor.
- Bank Configuration - Defines which injectors are on each bank of the engine when using independant bank lambda control.
