P29 Ecu came stock on Si Civics here wich have a DOHC ZC. I Wanted to know if it was obd 1 or 0? How can i check? I'm Mounting my apex'i timer, just wanted to know if it was worth it to pull out the computer.

I know this probably has been answerd before, but i could not find anything.

 

P29 ecu's are OBD1.

 

That's what i have heard, my confusion comes because i cant see the o2 sensor anywhere, my car dosent even come with a catalytic converter.

Ok, i'm really confused, in order for the ECU to be OBD 1 it has to have an o2 sensor, right? So, where is it supose to be?

 

one of 2 places... either on the front part of the header in plain sight, or on the lower part/collector of the header.
From the driver side, look down under your intake manifold and you should be able to see the collector area of the header.. you will see the o2 then.
