I've looked into it and I doubt any will work reliably. The O2 sensors are too sensitive in these cars and it will likely trigger a CEL if you get on it.

What do we have for options then. Jb4 support the cel delete yet. Or is bm3 out only option

Not sure what spacer setup Titan Motorsports uses but no cel lights with piggyback setup

Oh yea? I wonder if their module mitigates the CEL

It is a fabspeed precious metal extender. Pretty pricey but if it works its worth it. Wish jb4 could take care of it.

Yea, I think it will work most of the time, but a CEL may trigger under hard driving.

O2 spacers will usually not work for the long time on these ECUs and sensors because they are sensitive and the ECU watches everything. We can fix you with a tune. Hit me up.

These things rock - they are basically mini cats (minus the drawbacks) and you will not get a CEL with it installed.

I've had these installed on several Lambo's I've owned with aftermarket exhausts. No more CEL.

That's super neat, never heard of it but I like it. The only issue is I don't know if it will fit, it's pretty tight down there.

That will get rid of the P0420 Cat efficiency code, but with spacers and stuff I have been getting a P0141 OBD-II Trouble Code: O2 Sensor Heater Circuit Malfunction. These sensors are very very sensitive as previously stated... Imma try one other style and if that doesn't work, I will live with the light until I get tuned... FYI, these are the ones I have tried so far...

1st one I tried with smallest orifice... got P0141 permanent code
2nd one I tried would still not pass P0141 due to being over the ohmic value threshold
3rd one passed p0141 a few times but failed while sitting in traffic today, and also got a P0420 permanent code with it as the orifice is too big
4th one is on the way, it has a built in mini cat to kill the P0420, and hopefully it works to kill the P0141as well... and it will be the last I try

Keen to hear how you go. Are you running a decat dump on the factory tune so far?

Yes, stock tune with Titan downpipe

I've not personally used these (yet) but have heard nothing but good results from other users: https://www.fabspeed.com/universal-o2-spacer-with-catalytic-converter-single/
