Hi guys

I was reading this old topic about going from 1.25 fiesta to 1.4 .

I wanted to know if this worked??? because im doing the same,but the ford dealer told me that i might have some issues with the car key,he will not reconize the 1.4 ecu and the car may not start.

Did you have any problem doin this? i got a ford fiesta mk6 2003. the 1.4 mk6 engine i wanted to buy looks the same,(same plugs etc)

i'll really aprecciate your help!!

Thanks
