Default disconnected battery...how long until ecu relearns itself?

Hey guys, I had to disconnect the battery to change out the starter on my car and now the car idles rough....between about 750-1000 rpms. I also just got my ecu back from atp. Other than the idle the car is awesome. But Im not sure if I need to do a throttle body adjustment, cleaning or what, because I didnt have this problem before. Also no check engine lights. My ABS and Brake light are on but I dont think that that is related. Anyone with any ideas, please let me know.
Thanks.
Josh

After reconnecting the battery, turn the key part way, do not crank. Wait 3 minutes for the throttle body to allign, then start. The ECU should relearn within 100 mi.
