So if i were able to get a ST ecu would i be able to switch it to the SE and be able to get a tuner. If so what parts would i need to change with the ecu??

Interesting. Can’t imagine that the ST strategy would be remotely close to supporting an NA motor where that a tuner could even overcome base difference

I would say it's VERY unlikely the ST ECU would run on the SE. Fueling is way different, timing is probably different due to the ST turbo. It would need to add much for fuel as "boost " would come on. Your SE would get fed to much fuel. Also timing and advice would be off.

I wouldn't do it.

Ford ECU can not be flashed. So I am told. If you find a solution, PLEASE POST IT...

I talked to a local tuner about a year ago (2020) and they said they can not tune the Fiesta SEs (normally aspirated) sadly
