Guys the 1.6 engine has two ecu for it the

IAW5NF T-1

IAW5NF T-9

i noticed in eper that it has different countries for each with one saying northern countries while other saying turkey or what not. what is the difference between these two ecus. i am in the process of purchasing one. i also have the 3d dynamic model i dunno if that plays a role also.

i just want to make sure what to watch out for. i mean i have the t-1 and bought the car in greece. if i purchase a t-9 will their be a slight difference in performance in the engine or what not? should i stick to buying a t-1 that came with my car or just get any if i come across it?

Not sure about an ECU, but usually when ePER specifies a different part number for northern countries, it just means that one is more corrosion resistant.

You can change it to T9. About climate there is an update for both ECU`s - it fixed the problem with TB and MAP. When you buy used ECU you need to make it "virgin" before installing it to car to make it read immo and adapt to car.
