Description:
FD3S AEM Series 1 ECU, plug and play. Working & tested. I can include a base map to get you going for stock twins much better then what AEM provided. These are still great ECU's for those looking for a PnP setup.
I do not believe this one was ever "updated" by AEM so I suggest sending it out to be updated by FF Chips: https://www.ffchips.com/aem-ems-series-1-2-repair/
Plug and play ECU that can control the stock twins. The base map I will include works great for a stockish car with 850cc primary and 850cc secondary injectors. You will need to wire in a wideband o2 controller/sensor so the ECU can have o2 feedback control.
