How does this effect the air and fuel systems?

the ect tells the computer if the engine is cold or hot..when cold the computer will inject way more fuel than it does when hot.[like a choke on a carb]when warm,the computer doesnt give nowhere as much uses this ect to sense the temperature to determine how much fuel to give it.
