hi this was suprisingly simple with the fiatecuscan software .
1 install full version of fiatecuscan
2 connect green cable to diagnosis plug (side of dash under fuse box)
3 connect elm cable to green cable
4 connect elm to pc
5 start programme and turn ignition on(so dash lights are on)
6 click settings - interfaces tab -scan for interfaces
7 once its scanned it should show a connection on the interfaces window(if not make sure connections are tight and do scan again it took me 3 attempts)
8 now you need to click the test button and it will run a quick test of connection now your set up you can close the settings window
9 now you select vehicle and which system you want to check mine was punto sport 16v and delphi electric steering
10 now click connect
11 this next window shows you all the info on your connected device (power steering)
12 check for errors mine was clear
13 click adjustments
14 start the engine straighten the wheels and click torision setup
15 click execute this took less than 30 secs it says done
16 disconnect everything and try
it worked first time for me but you can do it again and there are also other options to centre the steering wheel and a couple of others.
hope this helps others i done my best to tell what i done and i no it sounds alot but it really only took 5 mins i not a mechanic or anything just a trier and this worked me
