I've posted about this before but I cant remember where. Its a program that you download from the Fiat website onto a USB stick and then put it into the car. It uploads the software to the car and 5 days later pop the stick back into the computer. It will break down all the data and let you know where you can save money by changing gear better, better acceleration ect. Its not really meant for Abarth but it does work.
P.S. when you set it up on your P.C> you have to tell it your driving a grande sporting 120 T-jet.
