Oxygen Sensor Extender
Been doing a lot of research on installing an HHO unit in my cars and I was curious if anyone has had good results with an Oxygen Sensor Extender alone?

RE: Oxygen Sensor Extender
I hope you have room for 2. I doubt one is enough.

Since an extender moves the sensor out of the exhaust flow, using several extenders might cool the sensor enough where the heaters may have to run more and eventually fail. Still I'd be using two if I had the room. Blush

RE: Oxygen Sensor Extender
So if the heaters fail, does this mean they don't work?Hmm

Well, Bob, that's just a theory a few of us threw around in an E85 forum.

If the heater fails, you'd need a new sensor.

RE: Oxygen Sensor Extender
Let me rephrase that question. Are the extenders a bad idea because they can damage your oxygen sensors?

IMO, I believe one is ok, two is pushing it, more is foolish.

RE: Oxygen Sensor Extender
Can you get away with JUST using an extender without using ANYTHING ELSE? Will the ECU cooperate?

I've got just one, no EFIE and can't see much difference. My mixture still runs a little above stoich (a little too rich).

RE: Oxygen Sensor Extender
Mine has since come out. No gain and possibly a small decrease (1 mpg) in mileage when I had it installed.

If the heater failed, you will throw a defective heater code. You'd get bogus o2 readings at idle in winter and it would take a lot longer to get the sensor up to proper temps in stop and go driving. I suspect you'd be ok at highway speeds. I don't know if you'd spend more time in open loop or how that works, I can only speculate.
