Default PM7 question

first of all, big shout out to Jason, damn that is a lot of well appriciated work to give honda owners a cheap (free) engine management system.
my question is this, i have a dohc zc, the motor stamp reads 88 i believe, but the JDM PM7 ecu was sent seperately and im not sure if it is also an 88.
how can i tell if my ecu is an 88-89 or 90-91
im just trying to find out if i will need an adapter to burn the chips.

my head is spinning right now from all this info ive been cramming in the last 6 hours. a lot of info and lots of it has gone right over my head. im just sticking to the faq and the posts for info as much as i can

No, shouts to you! You inspired my turbo setup.

If the ECU *is* JDM PM7 for sure, it'll be external EEPROM.

You also could just pop the top off of the ECU, snap a pic, and I'll tell ya.

Damn old post here but:

88-89 and 90-91.. both of those generations had the external roms and some also didnt..

When using my pm7 for my b16a, i had to go through 3 pm7 ecu's and ended up getting one from 89 or 88 that had the external rom.. the other 2 didnt have the roms, and were both 88-89 to 90-91
