Default How to tell difference in 86-87 and 88-89 PG7's??????

I serched and couldn't find anything really. Is there someway to tell the differences in the years just by seeing the case? I've read somewhere that one of them has an X stamped on the case and one doesn't i'm just not sure which is which? Anyone have any idea? ....Thanks

or

1st gen CRX Si ecu and 2nd gen (88-89 not 90-91) ecu? Sorry I suck at ecu codes .

86-87 PG7 will have part no. 37820-PG7-66# if it is manual transmission, 37820-PG7-67# if it is automatic and looks like this:



88-89 PG7 will have part no. 37820-PG7-A0# if it is manual transmission, 37820-PG7-A1# if it is automatic and looks like this:

OK well the part number of the one I"m looking at on ebay 3728-PG7-A131 but it has an X stamped on the case like the 86-87. These are the pics of the ecu that are on ebay. in the first one you can see the x stamp and in the second you can see the part number. So... it has a stamp like an 86-87 but a 88-89 part number. Guy says its from an 89. I just wanted to be sure what I was bidding on. Could it have the stamp because its an auto ecu?

he prolly stuck that on there because its in the wrong location....it IS a 86-87, I confronted a guy about selling a 86-87 ECU on ebay before as a "88-89" and he was pissed, I even went so far as to email all the buyers about that, and he got pissed at me when it didnt sell...lol

well looking at the pics again I just noticed that in the pic with the part number it doesn't have the stamp. I'll have to email him and ask for a pic of the build date on the ecu. The seller has over 18000 positive feedback....not sure if he would try to scam on purpose.

it is possible that it is 88-89 ECU with 86-87 cover on it - if it is, however, 37820-PG7-A131 is definitely for automatic transmission

but JLI, look at it man the ID sticker is in the wrong spot, supposed to be centered or near it not on the edge of one of the ends like it is.
