    Anyone know how to make a o2 simulator for a ls1?

    Ok, I'm getting sick of throwing po134 and po154. I've cleaned the o2s and replaced them twice now wiring is ok. So now I'm just thinking about making my own simulator. I've looked all over and got nothing. I have a set of sims on the back pass the cats I don't have anymore. So if anyone knows how to make them it would be a lot of help to me and others. Thanks

    Those codes mean there is something actually wrong, you can't fool the upstream O2s and even if you did it could end up being a serious problem and mess things up a lot. I wouldn't even try this I would try and find the problem.

    those codes are common with headers.....do you have headers? What O2's are you running and how many miles are on them? You can't just sim the front O2's. You have a couple of options. You could try to wrap the headers to retain more heat and hope that helps, you could try going to bosch 13111 sensors and hope that helps, you can have a tuner set those codes to not turn on the light, you can have a tuner delete those codes altogether, or you can tune the car to run open loop all the time and do away with the O2's. None are real good solutions unfortunately.

    Yea I have long tube headers 1-7/8, and the o2s are only have maybe 3000 miles on them. They are one of the boschs I ran on my ls1 that cost me like 80 bucks a o2. I just did the ls6 swap and all wiring is good cleaned the them up with break cleaner and ran great til a 1000 miles or so. I'm thing tune since ut a different motor
