I wanted To know what the letters on the ecu stand for or mean, mine has ay, exept the y is backwards an ie seen some with a z on them and a few other variations, what does it mean?

the backwards y is a Japanese letter i think.
as fas as what they stand for, iirc there just a lot number. makes it easy to id a re-called ecu for defects.
