Hello,

I did not find any forum for Fiesta so I post here.

My problem is that I find the screaming treble. I own the Fiesta with the original car audio and Sony speakers :

I heard about "FORscan" that would just give a signal flatter than that sent by my car. Have you ever used or know this software? And how do I know if my car is compatible with it or not?

Thank you in advance !

 

Welcome to the site

FORScan is a great platform for code retrieval, diagnostics, live data streaming, and does offer some programming features. The download is free, but Windows based covers the most options/features. I use FORScan, and I’d suggest looking on their site for model compatibility, and you can try contacting the developer to see about specific programming needs, meaning what they/you can and can’t do. I haven’t heard of being able to change trebble note though..

 

Oh, I heard that FORscan could improve the signal from the OEM.

Too bad...
