Which Is The Ecu Serial Number?
Pardon me for the dumb question but I got the ECU out of the car and in the process of filling out the form to send it to Hondata. It asks for the ECU serial number. I'm confused which number to put down in the form. Is it the numbers directly on top of the bar code, or is it the one begins with CY-Eh2562a or is it the one that starts with No. 510815?

CY-EH2562A 510815 (per your example)
I just sent them (per your example) 510815 and everything processed just fine.
