Multiecuscan

I have just replaced the EPS in my Niece's Grande Punto 1.3 multijet (90hp) and as soon as I re-connected everything I had lots of different faults pop up on the dashboard, I managed to go through calibration and the power steering appears to work but before I go any further I would like to know the following:-

Some websites suggest the ESP unit requires coding to the car, is this correct and if so can I do this through multiECUscan?

Also is there anything else I should be aware of?

Many thanks

Colin.
