Steve- Here is a simplified procedure that works for 5.2 and later Motronic Ferraris. Gleaned from several WSMs. Got tired of typing it so turned it into a word document.
Turn battery disconnect switch off and turn off all accessories (stereo, A/C, etc).
Let engine get completely cold or wait at least 30 minutes.
Insert key in ignition and leave for 30 seconds.
Turn ignition to on and leave for 30 seconds.
Turn ignition off and leave for 30 seconds.
Turn ignition on, wait for Check OK, and start.
Let idle with no input whatsoever for 10 minutes.
Turn accessories back on and drive gently for 10-15 minutes at least.
You will have to insert stereo code, if required.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
