Why do you want to do computer matching when cleaning the throttle?

Computer matching must be done when cleaning the throttle valve, because the cleaning of the throttle valve must be due to the blockage of the trachea. At this time, the computer cleans the throttle valve according to some relevant matching of the blocked trachea, and the relevant computer matching must be done. Otherwise, it does not meet.

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine.

It is precisely because the electronic throttle has self-adjusting function that it needs to be matched after cleaning. Assuming that the throttle opening is 8% when there is no carbon deposit, the throttle will open wider and wider when there is more carbon deposit. Assuming that it reaches 18%, the carbon deposit is cleared. It is impossible for the cleaned throttle to know that you cleaned the throttle in a short time, so the computer will think that the opening at idle speed is still 18%.

Now that the carbon deposit is gone, the throttle valve is unobstructed, and the opening of 18% will lead to excessive intake, increased idle speed or unstable idle speed. Throttle matching is to restore the computer value to the state of 8% idle opening, which means that the computer and throttle are the same, so everything is normal.

Cable throttle has one more component than electronic throttle, that is, idle motor. The electronic throttle has no idle motor. When the fuel filler door is idling, the throttle baffle of the cable is completely closed, and the air required for idling is entered by the idling motor. Therefore, the cable throttle has no self-adjusting ability. If you don't step on it, it will be completely closed. How much to turn on, whether it is cleaned or not, the computer always thinks that it will be completely closed without stepping on the throttle, and there is no need to match it.
