Which ECU for the Scion FR-S (ZN6, FA20)?
Every ECU below has a harness for this car. They all run the engine basics; the difference is how many of the stock ECU's other functions each one can still wire, and how much spare I/O is left for add-ons such as boost control or a wideband. “Of 0” counts the stock functions at least one ECU here wires.
No harness has been built for this car yet. The fit check for each ECU is below.

Categories are read from the stock pin names and are a guide; each item shows its full stock name. Power and ground pins aren't compared, since every harness powers and grounds the ECU. Prices aren't considered. Always check the harness's own findings before building.
