REMOVAL
USE THE DRB SCAN TOOL TO REPROGRAM
THE NEW POWERTRAIN CONTROL MODULE
(PCM) WITH THE VEHICLES ORIGINAL IDENTIFICATION
NUMBER (VIN) AND THE VEHICLES
ORIGINAL MILEAGE. IF THIS STEP IS
NOT DONE, A DIAGNOSTIC TROUBLE CODE
(DTC) MAY BE SET.
To avoid possible voltage spike damage to the
PCM, ignition key must be off, and negative battery
cable must be disconnected before unplugging PCM
connectors.
(1) Disconnect negative battery cable at battery.
(2) Remove plastic shields from over four electrical
connectors. Shields snap to connectors.
(3) Carefully unplug four electrical connectors (3)
(Fig. 5) or (Fig. 6) from PCM.
(4) Remove three PCM mounting bolts (1) or (2)
and remove PCM from vehicle.

It won't take that long for the PCM's adaptive memory to learn the new parameters. I'd say within a couple hours max if you are taking short trips during those first hours. It might run a little odd or rough until it gets back in sync.
