how does the ECU know when to cut fuel when you over boost? what sensor is it using?

Its determined by the signal from the airflow meter.

it cuts the spark but everyone call its fuel cut. theres a couple things that makes it do it. air temp sensor, i think a coolant sensor? the air flow meter...thats all i can remember
