Fiesta ST ECU - North America vs Europe

7566 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.

Phil, contact Jay at Finsport.co.uk. They do the EUDM ecu's and have a flash tool so you can go back to stock.
Its not really an OTS map. You need to download your current map and e-mail it to them. They then look at values stored in YOUR ecu, and adjust accordingly, before they send you a map. Each cars ECU map tables will look different than a stock map off the factory floor.
@phil, loaded the Finsport Stage 2 map this morning. Its amazing what it does to the car.
