Do you have the check engine lite on? Do you have any codes that tell you the oxygen sensors are bad.
If you have an ECU programmed for the oxygen sensors it will automatically come with the cel lite on. It will read them immediately.
If you dont then perhaps you dont have them programmed into the ECU.
ME, you got a pain in the ass. A engine ECU will need to be looked at to see what country it is actually from and what the standards for that country are.
Tell me what country do you think it is from.
I can do some research to see what if any the ecu hardware should be.
