Which O2 Sensor for LT's?
 

I have Lt's on the Z and I replaced the O2's on the front and have the 02 extensions on them.. the sensors have gone to shit... throwing codes, I've read somewhere that there is a 02 sensor with a long enough cable so I can do away with the extensions. Which one is this and are they anygood?

Thanks

The Denso 'vette rears were not adequate for me with
Jet-Hots (coated) to avoid heater codes. They seem to
be functioning and haven't messed the trims around.
But not a "no codes" fix. Some people seem to have
done better with the Bosch 13111 and some just have
no luck.

it is extremely important that you get coated headers....
as most of the time the bosch 13111's are still hit and miss with uncoated heades....but I have not had a problem yet as long as teh headers are coated

I do have coated LT's...

Thanks for the info... So, the bosch 13111's have the long wires??

Yes, very long.

I sure have :( 16 oxygen sensors in 50K miles.

you might have something else going on if you've been thru 16 sensors...possibly running way too rich and fouling the sensors??
though I would expect you to be fouling plugs too if that was the case...

I've had the same set of 13111's for over 30,000 miles...

Ive tried many things. Adjusted my tune a million different ways. Plugs look great. No black smoke. Idles and drives well except for some minor bucking from the cam. Ive changed my exhaust and made sure I didnt silicon poisin them or anything.

Bosch 13111s last the longest for me, usually about 10K or more before they throw the insufficient switching code. Although ive received a few bosches that threw codes immediately but exchanged them under warranty.

IF you have bucking usually your fueling is not correct..sometimes spark....
I have tuned T-rex cams with no bucking after fueling is correct...

Yes, perhaps at those certain transitional rpms and maps. Ill take care of it when I replace my stolen HPtuners and get wideband.

Anyway, I blew through quite a few o2 sensors before I had the cam. Again, I had no black smoke or anything, and the plugs and o2 sensors visually looked fine.

Thanks for the info, but i dont want to jack this thread.

Exactly. I believe o2 sensor life is greatly related to the tune. I've removed a few ls1 owners fouled o2's, in most cases the car was untuned.

I tuned my car since day one of my LT and o2 install. I have approx. 20k on my Bosch 13111's. No codes yet.

As did I. I have never had LTFTs stray farther than +/- 4 when fully settled. I have never fouled a sensor. They come out a clean dark brown without any carbon buildup. I'm always open to suggestions though...

That has to be frustrating beyond belief. What brand o2's have you gone through? Is it throwing codes or do the o2's appear to be visibly dying when viewed on a scanner? How about brand of gas used? Bring the car by if your ever in the midwest.

It goes something like this

4 stock OEM sensors,
2 Bosch f-body sensors
6 Bosch 13111s (2 were dead right away)
2 Densos
2 Current Bosch 13111s

Theyve all have perfectly acceptable wave forms at cruise. They were all a little slow at idle, which is to be expected. The denso's were slowest of all. My codes are usually "insufficient switching" codes, although ive had a "slow response" or two and a heater failure.
