Fiesta ST ECU - North America vs Europe

7563 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.

Isn't Ford Racing going to offer ECU/intake/exhaust upgrades for the FiST that will add power without voiding the warranty??
+1 on that!

VW refused to honor the powertrain warranty on my 2011 GTI after it spun a bearing stating alternately, I had a tune (APR) and I competed in it (SCCA autocross). Then APR discovered the oil pressure drops below 10 psi under hard cornering loads...bazinga! But no joy. That's why I'm trading it for a FiST...
