I think it's about 20 minutes of driving, which should include both runs at highway speed and some stop and go. If you have a scanner you can check for yourself when the "not ready" code goes away.

You could have a blown fuse. If power is not reaching the "back up" wire on the ECU, it's memory will be cleared (and a "not ready" code set) every time you turn the key off. This same fuse supplies power to the radio so it's kind of common to blow it when installing an aftermarket radio. I don't know offhand exactly which fuse it is though.
