If you are looking at an ECU, how can you tell which MY it is from?

Thanks!

 

i don't know, maybe there is a serial number you can match against a honda database/parts listing...

 

yea, gonna try the parts number thing this week, if everything works out I should be ordering an 02 ecu this Friday... hopefully it works out and I can sell my 00 ecu to someone with a f22 who wants to enjoy 9000 rpms, lol

 

apparently all ap1 ecus have the same part number...

 

here's the part number format

37820-PZX-A09 through A14 these are the newer reflashable ecus 06+

all start with 37820-PZX, the last 3 digits are the ecu's revision level, you can look up the ecu part number for each model year to determine which revsions match up to model year. some times there are more than one ecu revsion for a model year.

 

You can tell year if you have the VIN # with it. I think it's the digit before the T. IE xxxxx3Txxxxx is and MY03
