Fiesta ST ECU - North America vs Europe

7559 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.

No worries though, we've got you covered!
Great News!
Isn't Ford Racing going to offer ECU/intake/exhaust upgrades for the FiST that will add power without voiding the warranty??
That remains to be seen. I will keep digging.
In meetings with Ford Racing, I have expressed the need for a factory-backed upgrade path that keeps the warranty intact on more than one occasion. It's not necessarily that they don't want to do it. It's just that it's a labyrinth of issues when you're talking about that type of program.
We have a direct line to mountune so, if and when that would be announced, we'll have the news. However, due to US and European laws being so different, I'd have to say that I wouldn't hold my breath. But, they may surprise us.
