What should I pay attention to when changing the independent throttle?

Answer: Avoid inhaling hot air. Naturally aspirated cars can be changed, and so can those with one side of intake and exhaust, but it is a bit troublesome. After everything is ready, put an air flowmeter on the horn and adjust the throttle opening at idle speed to make the speed of each cylinder consistent. Is the speed of the crankshaft, has nothing to do with the opening, only related to the air volume. The independent intake valve was changed, mainly due to the computer. You must use vacuum pressure as data (MAP, Manifold Absolute Pressure Sensor). There is no way to use MAF (mass air flowmeter). Therefore, Honda's car can be easily switched to ITB, because the original factory uses a map. If Nissan and Mitsubishi both use MAF, the computer needs to be greatly changed, Honda only needs to brush rom, and the ROM skills of B series computers can be read.
