What kind of modifications do you have done to your engine?
try www.hondata.com they can provide you with some more info.
You would have run and obd-1 ecu (p28 or so) and a jumper (obd2 - obd1).
Unless you have extensive mods done, it's not really worth spending the dough on the ecu. Stay away from the $15 ebay chips they are worthless.
If you do chip your ecu, don't go with a static chip go with something programable so you can make changes in the tune as you make changes to the motor....
