Anybody know how to rig the secondary O2 sensor on an all motor OBD2 setup, so the ecu will think i am using it behimd the functioning cat when i am not. The reason I ask this is because i bought a JDM header to replace the cat/manifold crap that i curently have. The header fits fine to the rest of the exhaust under the car with no room for a cat. Now since the #2 O2 sensor doesent effect the A/F ratio but will throw a C.E.L. if unpluged im just trying to figure this out.

 

how bout an o2 sim?

 

get a chipped ecu
