6.11 Throttle Matching
This function can utilize the diagnostic scanner to initialize the throttle actuator so that the learning value of the ECU
returns to the initial state. By doing so, the movement of the throttle (or idle motor) can be more accurately controlled,
thus adjusting the intake volume.
It needs to be performed in the following cases:
• After replacing the electronic control unit, the relevant characteristics of the throttle operation have not been stored in
the electronic control unit.
• After the electronic control unit is powered off, the memory of the electronic control unit’s memory is lost.
• After replacing the throttle assembly, you need to match the throttle.
• After replacing or disassembling the intake port, the controlling of the idle speed by the coordination between the
electronic control unit and the throttle body is affected.
• The intake volume, and the idle control behavior has changed while staying at the same throttle opening position,
although the idle throttle potentiometer behavior hasn’t changed.
6.12 Gearbox Matching
This function can complete the self-learning of the gearbox and improve the shift quality.
It needs to be performed in the following cases:
