O2 sensor simulator

Does anyone have a link for a place to buy oxygen sensor simulators? I have had down pipes for awhile now and the SES light is starting to bug me. Www.o2sims.com or whatever it was seems to have vanished from the internet and they are the only ones people seem to have mentioned.

Google area seventy 4, that's what I used and they worked flawlessly.

I've reached out to the tuner to see what can be done as well. Wanna double check to see exactly how they programmed the car. If the second cat is "turned off" I will have no choice but to go get it tuned anyway before it will even read the simulator.

Yes one for each sensor therefore you will need 2. After numerous unsuccessful attempts by my tuner, I ended up using these simulators and they worked great. Occasionally it trips a CEL when I’m driving WOT for extended periods [on track] but simple reset with my phone does the job. For everyday driving and street it’s never tripped a CEL. This simulator should work on all engine platforms, m54, n52, n54/55, and s54.

Yes but for N55 you’ll only need 1. And install should be little easier because N55 is more accessible. If your m54 is anything like mine where the post cat o2 sensor connects underneath the car, you will most likely install on the DME side inside the ECU enclosure. And honestly I prefer that anyway because the sensor is protected from the heat and weather (and remains hidden). Removing the ecu took more time than installing the sensor.

Pictures are down but my brief write up:

Hi all, i ended up buying two simulators from magnum tuning and they work great. They were still pretty expensive but they worked. They were simple to install. I bought the ones that dont have the heater circuit in them as they were way too expensive but i wish that i bit the bullet and bought them for completeness of the mod. I am going to make a small metal box and house the heaters to avoid excessive heat under the hood or perhaps find a suitable resistor (something heavy duty like ceramic) to bypass the heaters.

No codes so they 100% work
