I got this JDM FD that has a FAM speed plaque rivetted to the firewall but it has a N3Y7 ecu cover on it and one of the screws has been filled with solder. so they obviously chipped it.
my other one has the n3a7 ecu

just wondering if anyone knew which year the n3y7 is from

searching doesnt show anything google i just find one on ebay for sale

this is the same as mine, theres the solder on the screw, that red sticker is stuck over the stock one

thanks anyways , they're looking for a S5 TII ecu n370.


no one knows?

 

That part number prefix is not from a JDM FD.

Maybe it's a yankee/euro ECU that someone has installed?
