Most likely its a 90-91...open the top cover and look inside. If you see a 28 pin eprom, you are good to go.

Post a picture of the inside of the ECU if you dont understand what I mean.

the date on the side will be accurate, however, keep in mind that sometimes, 1990 model cars were made in 1989, so you might have a chippable ECU that will read 89 on it. (i had one)
