I would suggest sticking with a manual transmission ECM to use as a replacement. Yes, The ECM will have a sticker on it with the part/model number. You might want to search the internet to find a company near you that can re-flash them. I've attached pictures below of where it is located on your car and also the Hyundai factory part numbers for the options for your cars ECM. Hope this helps and thanks again for using 2CarPros.
