The ems is different for 00-01, so im guessing there were changes to the stock unit too...

What are they?

 

are you talking about the ecu? Cuz a lot of things on the gsr is stamped p72

 

Addition of the immobilizer function.

 

Yes, I was refering to the ECU...

If I buy someone elses ECU does this mean my car theoretically wont start with their ECU?

the harness matches up?

 

Are you asking about OBD 2a and OBD 2b differences? And how to identify which is which?

I believe there is a OBDII-OBDI harness. So it can be done.

Correct. But it is technically OBD2a - OBD1 harness. And OBD2b - OBD1 harness.

 

What is the ECU in an 01 GSR? is it a P72 ODB IIa?

 

I used a harness, and didnt have any problems with the emobilizer....worked great.

It should be a P72 OBD IIb. But you should check the connectors to make sure. If you click the link I posted above....you can see the differences in ECU's from the picture. Oldest on the bottom- Newest on top.

I have a 98 Gsr and that used a P72 OBD2a Ecu. In certain late model 98 GSR's on up they used P72 OBD2b Ecu's.

 

Your 01 Ecu should use the left 3 plugs and have a open space at the end. My OBD2a Ecu has a space in the center.

Correct, however my ecu doesnt have that rubber thing on the left side as the hondata page shows.

The rubber thing on the side isn't anything. Your just looking for the pins for the connector plugs of the harness.

 

do you know if there is anyway to retain the same key code on the immobilizer when switching ecu's?
