X-Post from the A6/C5 Forum - Which O2 Sensor Simulator do I need? LanceEagle are you out there?

Esquire6 · 01-06-2006, 09:36 AM

I plan to replace my Magna Flow High Flow Cats with the test pipes provided by LabRee and I understand that I'll need O2 Sensor Simulators to avoid a CEL. My question is, which kit(s) do I need? I can't tell from Baker's web site whether I need just the set for the test pipes or will I need something else. I see from LanceEagle's post that he used
"2 PSO2SIM's and 2 O2 Sensor Heater Simulating Resistors". Do I need the same set up? Thanks in advance for the help. I eagerly await this Forum's response(s).

replacing his high flow cats with a test pipe like I plan to do, then I'd have the same parts installed.

Are you guys convinced that the plug fouler solution will work on the S4? You are masking off the secondary sensors. I believe the ECU is expecting reasonable and varying signals from the O2 sensors and it compares them. I remember seeing some data in the VAG output pointing to out of range comparisions. I'll recheck after my PSO2SIM's
get here and installed. I believe that you have to electronicly make the ECU happy, or you will go into Limp mode. That's not worth the few bucks saved. I'll see if I can get an answer to this.

2 O2 Sensor Heater Simulating Resistors to simulate your O2 Sensor Heaters.

You can leave your original O2s connected to their harness' if their heaters are working fine and just not buy/hook up the Heater Simulating Resistors.

For me, I wanted those O2 Sensors gone so I replaced it all.

If you have any other Q's for me feel free to mail me directly. I don't troll a whole lot on here

If his set-up is for just replacing his high flow cats with a test pipe like I plan to do, then I'd have the same parts installed. __________________
