Hello

No this is not possible, as the software is written to the PIC and can not be changed

This also does not make sense because there are other ELM interface v1.4 or v1.5 to buy for little money

And why should be wrong for your Ford Mondeo version v2.1 ?????
With Multiecuscan you can read at your Ford no control !!!!

Use times Forscan.org
