Does Ruifeng m3 throttle need to match?

The throttle valve of Ruifeng M3 needs to be re-matched after cleaning. After cleaning, if it is not reset, the throttle opening will remain in the state before carbon deposition, and the intake air will increase, resulting in unstable idle speed and excessive speed of the engine.

All models with electronic throttle need to be matched. The electronic throttle has no idle motor, and the throttle is not completely closed at idle speed, so there will be a small opening. If the carbon deposit is washed away, the throttle opening will not decrease immediately, but it will remain open when there is carbon deposit. At this time, there is no carbon deposit, the passage becomes larger and the air intake increases, so the idle speed becomes higher.

Writing the actual throttle data into the computer motherboard is called throttle matching. In order to better adjust the idle speed of the engine, control the fuel injection and adjust the shift point, the computer needs the throttle to input the state data in real time. When the data changes, the computer will automatically adjust the throttle data value. If it exceeds a certain value, the engine will work abnormally. At this time, it is necessary to clean the throttle and write the latest state data of the throttle into the computer board, so that the computer board can adjust its working mode according to the new data.
