What lambda corrections do
The main Target Lambda table is your baseline. Lambda corrections sit on top of it and modify its output based on other conditions. Keeping those adjustments separate means your main table stays clean and describes the engine at normal operating temperature, while each correction handles one specific job.
Which corrections are available
| Correction | Status | Typical use |
|---|---|---|
| Coolant temperature | Always on | Richer targets while the engine warms up |
| Air temperature | Always on | Extra safety margin when intake air is hot |
| Generic | Enable from this node | Change the target based on any channel you choose |
| Fuel composition | Enable from this node | Adjust the target with ethanol content on flex fuel |
Once you enable the generic or fuel composition correction here, it shows up in the Lambda Corrections section of the NSP tree alongside the two temperature corrections, which are always there.
Our advice
Tune the main target table first, with the engine fully warm, then add corrections one at a time and confirm each in your logs. That way you always know which table is responsible for the target you're seeing.
