do SC ECU's relearn idle after the battery has been disconnected??

i just disconnected the negative side of my battery and after i hooked it back up and started my car up my idle was very low. (250) my car ran perfectly before the battery disconnection.

i was wondering if this is normal and i have to just drive my car and wait for it to correct itself or is something wrong?

thanks in advance

 

There is a ecu base map that lets the car start "just", it learns as you drive the car.

The auto trans has a "last 15 start memory", which tells the trans how "soft or harsh" to start from a stop, and drop back a gear.
