Air Flow Meter

Must I get a wide air flow meter to tune a car

Hello

im not sure if you are meaning a wideband sensor monitor or an airflow meter. but I will attempt to reply with both in mind,

a wideband sensor measures the air-fuel ratio

it certainly helps to have a wideband sensor monitor although a narrow-band sensor is also able to be used if a wideband sensor is unavailable.

a air flow meter is used to measure airflow into the engine.

in many factory engines and in most cases will give a finer tune than a map referenced engine.

i hope this helps we have many courses that will teach how this all works
