I was thinking about this too because i want to run open downpipe for a while and didn't know what to do about the rear O2 sensor.JRios said:Hey guys,
Ok, I have a 96' B14. What would happen if I were to disconnect the rear O2 besides getting a MIL? Is there any way to eliminate the rear O2 and not get a MIL without have to get my ecu reprogrammed by JWT?? TIA
So if i were to literally just cut the sensor off and ran open downpipe it would be alright??eric96ser said:All the rear o2 sensor does, is make sure the cat is working. The FSM states that it does not effect the AF values the ECU uses.
Yes but you would get an MIL. I just leave mine ziptied above the headshield.daveracer said:So if i were to literally just cut the sensor off and ran open downpipe it would be alright??
