Fiesta ST ECU - North America vs Europe

7562 Views 18 Replies 8 Participants Last post by  Drifter
Unlike the Focus ST, which shares the same brand of ECU in both the North American and European cars, the North American Fiesta ST ECUs are manufactured by a different vendor. At least that's the way I understand it.

This of course has the possibility of slowing down the R&D of ECU tuning on the North American cars. It may be a non-issue. But, I just wanted to share the info.

Maybe someone with more direct knowledge will be able to shed some insight.

Well Ford better get moving on this or they will be left behind. Even the no-powah FR-S will be getting a nice hp/torque boost in in the 2015 MY.
