Because of many reasons, my mechanic is doing my cam/crank shaft seals and t-belt and all the other good stuff while he is there. (really want to do it but no time and need it fixed) Anyways, usually he disables the battery to be on the safe side when he begins to work, here's my question, will the SAFC save it's settings or will it reset to defaults when the battery is hooked back up?

The S-AFC has a non-volatile memory so the settings will be saved.
