OBD1 is 92-95 for honda's (other companys are a little different but not by much). There is no A or B for OBD1.
OBD2a and OBD2b is when they desided to change it and it goes by the year. 96-98 is A and 98 up is B (or its the other way i never remember)
OBD = On Board Diagnostic (sp?)

more emissions control stuff. i know that obd2 systems use a second 02 sensor after the cat. not sure what the difference in 2a and 2b is tho. for tuning purposes stick to obd1. much easier to tune.
