OK. Searched but came up with nothing.

I am aware of what an o2 simulator does, but am not certain as to how it is installed.

I was looking at this one:
http://www.o2simulator.com/index.php...&products_id=8

I have a Random Technologies Cat, that had kept code free for a little while, but since winter, it keeps throwing the efficiency code, everytime I clear it. Rather than go through expense of getting a new cat and weld it in, I think I ready to try the o2 sim.

I've never actually seen one installed, so I am not certain as to what the deal is. It's a tiny box with wires in the pic, so I'm guessing it plugs into where the exisiting o2 sensor is?

Anyone help me out with a bit of knowledge please???

 

You have a PM.

 

PM received! Thank you!

 

Same problem.. PM please?

 

Can one of you please let me in on this? Or maybe post it in the thread? I'm about to install a decat downpipe on my R56 and need to know what the deal is with this simulator.

 

Can someone PM me on which O2 simulator will fit the R56 and how to install it?? thanks!

 

Just use a spark plug non fouler. Much cheaper and no wiring is required, all you need is a 7/8" wrench.

 

Will it work? or does it only work on some cars?

 

It always works.

It moves the sensor out of the exhaust stream.

 

A non-fouler does not work on an R56, or at least mine. I'm trying to find a simulator.

 

I am about to got the o2 simulator route as well. I cannot put an extension into the bung on the supersprint cat, there isn't enough room.

Any suggestions on where I can purchase a sim and how easy or difficult they are to install?

Thanks,
Bryan

 

you have a PM...

Easy to install...

This is nothing but a bypass so you leave your o2 sensor?! right where it is!

 

I have the same problem, can someone PM me HoW instal a o2 Sim. THANKS!

 

Hey guys does the o2 sim work? I am getting a Akrapovic DP for my 2010 R56 JCW and would like the sensor to be fooled rather than remapping the car etc..
Can someone also give me a link to where I can buy one that works?

 

vivid racing in the states offers a 80$ mini cat /90deg adapter I'm not sure about how well they work but worth a try maybe

 

An 02 simulator is nothing more than a ceramic resistor to make the heater circuit complete and show resistance and a cap or resistor across the measurement so it looks like it is reading something in the right voltage range on the sensor circuit.

they did work on older narrowband rear o2, cause I used one on my DSM after I broke the rear o2 off. Once upon a time narrowband we’re significantly cheaper and those were issued 8n the rear cat working YES/NO position.

they generally don’t work on wideband 02 which most cars post 2000 have aft of the cat.


Before you go trying a bunch of fixes, have you tried a new/ known working rear o2. They do fail both on the heater circuit and the measuring circuit and both will throw a code. If you know your o2 is fine, ie tried it in a different car, tried a different on on your car, then you can proceed to things like the right angle spark plug anti fouler, or right angle relocation with mini cat.
