So, my rear o2 currently has the fouler spacer thing-a-ma-jig...so if I remove said rear o2 and fouler, install wideband, and correct the ECU settings, this should do the trick without having to weld another bung for it, correct?

Would you happen to know how much the AFR's can differ? The rear o2 bung is located in the same place as where the factory placement for the rear o2 is. If this will not be an accurate reading, I will further invest in a new Megan DP and HFC. I should have never sold my DP to nsxerz

4 days is enough. any more and i'd probably be dead.

on the plus side, my blackjack winnings covered any out of pocket expenses, so i'm in the black.

giggity.

That is fine for placement. You can't totally remove the rear o2 because you will throw a code for the heater circuit. They are still working on a patch to fix that. Placement really affects reading the correct AFR at the correct RPM. fuel ratio should still be accurate as long as there are no exhaust leaks.

I read somewhere, it might have been posted here, can't you simulate the O2 sensor's heating circuit using a resistor? I have the problem on my car as well, though for the upstream o2 sensor since I replaced it with my wideband.

I also used the spacer technique on the rear O2 sensor to trick the ecu

I can use a resistor to simulate the heater circuit but it gets really hot and can fail over time. They are working on a SW spoof that will require no physical changes.

The only other consideration Timz is running the wire from the wideband o2 sensor if you but it in the rear o2 plug. There is a convenient grommet right near the end of the DP that is great for running that.

i think we should keep tally on how often the rear o2 discussion comes up

turcos you should start a thread with all the info and we should have a mod sticky it
