I disconnected the battery to reset the computer.

How long does it take for the computer parameters to settle in again.

 

The OBDII computer will have to go through a drive cycle and test all systems before it goes back to a ready status. Usually within a hundred miles. There are many different execution times for the various systems, but 100 miles of normal driving should cover all of them. For those of you that want specifics, here they are.
