After cleaning the throttle, the Vpecker E4 android initialization is necessary, because the computer to adjust the throttle opening time, there is a memory function, because before the sludge clogging.

In order to ensure the intake air, the computer will automatically adjust the throttle opening, Vpecker E4Air intake is in the normal state. And after cleaning. There is no sludge clogging, if the throttle also maintained the previous opening, then it will cause the intake volume is too large, the consequences are, when the engine jitter, and speed up the weak, the engine failure lights may also point bright.

Why sometimes do you need to do the initial cleaning engine after the throttle can also work properly? It is because the Vpecker E4 WIFI throttle is not too dirty, after cleaning, its intake did not happen much change. However, after the cleaning throttle changes can not be observed by the naked eye, it should be done to initialize.

 Vpecker E4 Android Light Vehicle Comprehensive Diagnostic Tool

After Vpecker E4 cleaning the throttle, the opening time of the throttle will decrease. This shows that the electronic control unit has a learning function.

Not only to check the changes in component parameters, but also to adapt to this change. But how does the electronic control unit know the initial parameters of the component?

 This requires initialization, if not done before initialization, if the electronic control unit received a throttle idle position of the voltage signal, but do not know its opening angle, this is because the electronic control unit does not know the minimum idle position throttle, the largest Idle position of the voltage and other basic parameters.

If the Vpecker E4 diagnosis electronic control unit to know the minimum idle position of the throttle, the maximum idle position, you know the idling throttle potentiometer voltage range, the Vpecker E4 electronic control unit to know the idle throttle potentiometer several intermediate position voltage value to know the idling Throttle potentiometer characteristics.

In this way, when the Vpecker E4 tablet diagnostic tool electronic control unit receives any position of the signal voltage, you can determine the throttle opening. Initialization is to let the electronic control unit to understand the basic characteristics of throttle body basic parameters, so that in the future operation of the process will automatically adjust it with the throttle action.
