afc backup, does it have one?

[commador]

hey all. Ive always wondered this. Does the afc have a battery backup or something? I mean, if you need to get a new battery for your car, do you need to reenter all the data, or is it saved? My friend is about to use one and I just though, what if the battery is disconnected??

Are you talking about the SAFC and VAFC? if so, YES, they don't lose the info stored on there unless you initialize all of the info within the unit itself. If you reset the ECU or dissconnect the battery it won't affect it.
