Hello guys, and for a long time that I wonder, in spite of something you learned about some of the ecu. is this:
depending on models and years,
the various maps of the ecu, you can repeat several times, also 3 as indicated, e.g.: ecm 1/3 etc.
they are all the same.
now what are active?
and the better I lose a lot of time to make them all the same.
someone knows something about it, whether it is necessary to do all of them or not?
