Note| t | to the display fields 1 and 2: |
| t | Low readouts indicate that the engine is running too rich and the lambda control therefore produces a leaner mixture. |
| t | High readouts mean that the engine is running too lean and the lambda control therefore produces a richer mixture. |
| t | add = additive - The effect of the fault (e.g. unmetered air) becomes increasingly less as engine speed rises. In the case of an additive initialisation value the injection period is changed by a fixed rate. This rate is independent of the basic injection period. |
| t | mul = multiplicative - The effect of the fault (e.g. faulty injector) becomes greater as engine speed rises. The multiplicative learned value is a percentage change in the injection period. This change is dependent on the basic injection period. |
