Oxygen Sensor Eliminator

[RIII BFT]

I saw this on Ebay and wondered if it was worth trying.
Does anyone have one of these (or similar) fitted and does it actually improve performance?
I have TORS and Cat Bypass fitted.

Clicked on your link and said the item has been removed. I got mine from dyno jet or dyna jet I can't remember which for about $15.

yea the O2 eliminator works as far as getting your engine light to go off.
The one from Dynojet anyway, can't speak for the one that was removed.
Improve HP?
Thats news to me.
I've got a single 3 into 1 pipe with no cat box and no O2 sensor though,
your results may vary....

It keeps the ECU from going into closed loop - using the signal from the O2 sensor to control the fuel. This is necessary when you put in a Power Commander.

If you fatten up the L tables to reduce backfiring in the pipes, the ECU will lean out those changes in closed loop. The O2 controller keeps it from doing that. But you can't change the L tables with the Tuneboy or (free) TuneECU programs, which have options to disable the O2 sensor.

Not necessary. Just uncheck the box and flash the ECU, same thing, for free and 5 minutes of your time.
You absolutely can change the L tables with TuneECU....

^ what he said - no simulator required
Remove sensor & install blanking plug in the bung hole & uncheck the box, save map & download
You can indeed then change the L tables and since sensor is no longer active, closed loop will no longer be able to over-ride those changes
But also note you may HAVE to add a little more fuel as it may be lean without the sensor
The easiest way to change that is to use the trim table
