I was just curious if there are differences in ecu numbers? My original ecu was marked 6574e and my new one which was from a manual as well is labeled 7378e. This Is the number printed on the outside of the covers.
Are these still compatible?
Also I noticed that the ecu board itself is marked different which is something else that concerned me.
The last 4 digits went from 989b and the new ecu is 989c
Here's pics of the two different ecu. My original is the one with the key driver chip. The new one doesn't have the chip installed.
