i didnt think anything of this when i had my ecu flashed to clear some fault codes a few months ago
my engine is a z18xe and when it was flashed the menu on the machine told me my engine code was z16xe. does this mean that my car is running a z16xe ecu or is it normal for these machines to come up with different codes? it would explain why my car seems a little slower compared to other 1.8's or it could be the hole in my exhaust that is causing it to be slower.
i am very confused by the engine code information though so if anyone can shed any light i would be very grateful. i wouldnt be very happy if my car is running a 1.6 ecu!
