Hello

I have a 2005 Fiat punto 1.3 JTD. I have googled for a while and have found some programs to read data from de ECU.
Now, I have come across two questions;

1-> Where to buy the OBD2 cable?(I'm not into making the cable..)where do u advise? i'm from portugal

2-> Is there any program or way to remap the ECU in order to gain torque/power through OBD2?

Thank you all in advance
