O2 Simulator for cats?

[supersporter13]

ok I just bought some headers for my 09 X-Runner and with that I got an 02 simulator that I attached to the ECU so that my check engine light will stay off. Where can I get one for my Camaro since I plan on running headers, no cats and TDs and I dont want my engine light on cuz isnt that one of the reason they wont smog your car if ur light is on?

most of our sponsors sell O2 simulators, but essentially any reputable F-body performance website is going to have them

Sims are worthless crap.


Get those rear O2 codes tuned out. That is fail-safe and costs the same.
The sims....hit or miss after a month.


That and sims are illegal in most places. Doubtful many places still sell them.

+1 i agree. get a tune and have your rear o2s deleted out of your computer

how simple is it to use a tuning device? Ive never had one or used one before...

[Mr. Luos]

Find someone local to do it for you. Shop shouldn't charge anymore than what a pair of sims costs anyways.
Local guy that has credits may be able to do it for free.

is there only 2 sensors on board? I thought they had to be kept becuase they also provide another fuunction

[Mr. Luos]

2 on each side.
One front (this must stay) and one rear (that one can go).

Well I guess getting a tune would be the BEST way. I run simms on both my 98 and 96 with no problems. Been on the 98 for over 4 years and the 96 for 2 years. Just got to make sure you zip tie them so they stay up and out of the way.

I had nothing but bad luck with sims. They would always burn out. I had mine tuned by madtunner mail order and have had no probs. Something to do with the cat heat. 98 ta wth stock manifolds,cat delete,and morroso spiralflow dumped under my seat.

I agree, havent even had my LTs, with sims less than a year and already throwing codes. You can send your pcm to Frost and let him tune out the codes for $125 if the price is the same.

I had it tuned out. Works good and you don''t have to worry about it going bad like sims can.

That's the key. Heat is what kills the sims. The ones we sell have the built in diagnostic circuit that illuminates an LED light to tell you they are still working. They are for off-road use only.

The other method is to get your ECU returned as others have mentioned and they just delete the codes associated with the rear O2 sensors from the ECU.
