I have just taken this picture of my XK8 2005 ECU and I seem to think the NA means this is a North Amercian spec ECU despite being in a UK RHD vehicle.
If I am right how do they differ in terms of specs / what is the impact? Do I try to source a European / UK one and if so which one is recommended?
Thank you in advance!
