92-95 Hondas are OBD1
96-98 Hondas are OBD2a
99-01 Hondas are OBD2b

i thought OBD2A was from 96-99
and then 00-01 is OBD2B
yeah i remember my friend's 99 R doesn't have the immobilizer function like my 2000

 

Immobilizer doesn't have any coorralation to the actual changes in the computer on OBD2b ECU's.

Sure it does. Model from 2000 and up Honda/Acura all have immobilizer function
which it only comes in OBD2B ECUs
I personally have not seen one OBD2A with immobilizer in it.
but i might be wrong so .. it's all good^^

 

The immobilizer is only in OBD2b ECU's, correct, but it does not mean that all OBD2b ECU's have the immobilizer. The immobilizer is a separate chip from the processing unit, which is what changed in the OBD2b ECU for emissions.

Try fitting a '99 integra ECU into a '98, doesnt fit.

No it actually does
92-95 OBD1 ECU running 3 plugs
96-99 OBD2A ECU running A, C, D plugs
00-01 OBD2B ECU running A, B, C, plugs

so basically it means 98 and 99 OBD2a plugs right in

 

Good info to have.
