Replacing PCM, part number intercompatibility?
 

I have a manual 2004 at 78k with the dreaded P0610. I
got a great deal on a used
N3Z2 18 881K, but my car has a
N3Z2 18 881L. Does anyon know if these are interchangable?

If it came from another S1 manual it should work. Mazda will have to reprogram it though.
