Run without O2 sensor?
I was wondering if its possible to run the car without an o2 sensor?
Besides the CEL comeing on...are there any disadvantages?
The reason why im asking is because i want to monitor my AFR, and was planning on throwing a Wideband in my downpipe....just wondering if its neccesary to weld in a seperate bung
Thanks

U can turn off the O2 in ur ems so it wont throw a code.
Or u can use most widebands as a narrowband to also not throw a code.

Re: Run without O2 sensor? (93supercoupe)
well its actually a WRX, and the EM im using i can turn off the CEL, i was just wondering if it will affect the performance of the car.......cause the car does have two O2 sensors, one in the header, before the turbo, and one after the turbo in the downpipe(where i would like to put the wideband)

and from what i understand, u can run one o2 sensor in an OBD2 car as long as you leave one o2 sensor in that senses the fuel

O i know
but the subaru boards were blocked at work, so i figured id try my luck on here first
and i meant leave one 02 sensor in the manifold, and put the WB in the DP,
and i learned before that the 02 in the manifold controls the fuel(which i will be keeping) and the one in the DP detects the cats effenc, so since im catless, its not problem
