I personally would not freeze the ECM. Moisture trap in the terminals will freeze and when thawed your're inviting corrosion into those terminals. If you remove the motherboard (circuit board) from the box you better wrap it in a electrostatic free material or you'll have a fried motherboard.

I begin by asking how often her oil change schedule and be sure to use the recommended grade. If she's been using say 10w-30 during summer, I suggest to change it now to factory recommended oil grade. Some gas stations are now receiving winter grade fuel, ask your fav station if they have winter grade or go to a station that has winter grade fuel.
