I replied to you Inbox:
AS stated earlier I will need your chassis number to be certain:
If your model is a CS5A 4G93 (1.8L sedan with CVT)
STHCR1D ECU A/T - MR560727
STHC ECU A/T - MR578480 (E6T30780) Estimated cost US$100
or MR593695 (E6T30777)
STPC or STXC ECU A/T MR578481 (E6T30781) or MR593696 (E6T30778)
The items with price I have been able to locate today but do have a time limit to purchase. You have 2 days to decide on that one.
Also 2001 is a transition year so I would need the production month of the car to determine exact ECU. (again exact chassis number will be needed)
Other ECUs may fit, but I will need photos of the ECU showing the connectors. See example here.

MR593695 & MR593696 & MR578480 & MR578481 should have the same connector output, so the difference in going to be in the programming but I have found that to work for others in the past with no noticeable difference.
ITEM 82500 is the ECU.
Happy Hunting.
