One of the cylinder is not firing and it was traced to the ECU malfunction. Now I need to change the ECU but my mech is not getting it right as all the ECU he got did not work with my car.
please what are the things to consider to get the right ECU that will work perfectly with my model.

 

You need the exact part number to match your PCM/ECU & it needs to be programmed to the vehicle & most likely the keys programmed to it.

 

Pls where on the ECU will I locate the part number? Could it be the L39L1881D?

 

From the image which one is the part number to request for a replace.
