Can a guy get away without O2 simms in an ORY? Can a person edit out the code it will throw w/o the simms.... and if so will that affect performance? Did some searches but my combo of search words is weird i guess....any help is appreciated.

 

You'll be fine... some people trip a SES light when running a ORY w/o O2 sims while others don't (like myself). As you mentioned, you can have the codes for it programmed out either way.

Won't effect performance running without rear O2's.

 

Actually editing out the 02 sims are easier and usally cheaper but not having them as long as the ses light isnt triggered wont hurt performance

 

So i can use my stock O2's in place of the simms? Or do I need some sort of plug for the holes on the collectors and WILL it affect performance if the ses light is on? What happens to performance once the ses light is triggered?

 

You have (2) sets of O2's. (1) before Cats and (1) after... you reuse two of the O2's and connect them to the bungs on the ORY. Most people run O2 extensions to allow for the harness to reach the new location of the O2's on the ORY.

People run O2 sims to simulate the reading that the now non-existant rear O2's send to the PCM, which basically just prevents the SES light from coming on. You will not have another set of bungs on the ORY to plug the last two O2's in either way.

BTW: The SES light will come on more or less as an Emissions related code. It will not effect the performance of the car. I've been running LTs with an ORY for several months now and no O2 sims. It's ran just fine.

 

Cool man, good to know i can get away with it w/o them...95.00 to keep the ses light off aint worth it to me. SO can I use like a hypertech scanner to clear the code if need be or does it need to be "edited"? I had a 98 with macs and a custom aap ory i dont remember him ever sayin he put simms in it and that thing never threw a code...

SO just stick the exisiting O2 in the bung in the header collectors and call it a day?

Thanks man, I appreciate the advice!!
