I got 03 AT coupe and love it. Sadly I got to car accident and now I have to find the ECU to replace the old damaged one. It is A64-000 LP6 and I was looking for it on Ebay and saw some but not exact number such as A64-000 LN6, A64-000 LP5, A64-000 LK6, A64-000 LN2, A64-000 LN5. I would like to ask what is the last 3 letter and number means? Any one that I mentioned above would be compatible with mine? Could anyone or expert help me with this? Thanks.
