How long does it take to clear the ECM when you disconnect the battery?

the reason i ask i bought the granatelli cai kit and the maf harness it came with didnt work. they told me to put it back to stock and wait for them to send a new maf harness. after doing all this and disconnecting the battery i am still getting check engine and running rough. any help is willing to be heard. thanks

AFord techposted that disconnecting the battery for 5-10 minutes is sufficient to clear the ECM.
