2012 KIA RIO 5dr Hatchback, Model: EX, 1.4 CVVT Engine, A/T
Hello! Does anybody know the current ECU version of the 2012 Kia Rio EX HB 5 dr? Does anyone know where to find the ECU version or this is something that the technicians can do? If I will ask my dealer to update it to EURO2 version, has anybody done this? Is it true that if I update it, my fuel consumption will improve? as well as the engine knock issue will be gone?
