Default Oxygen sensors for SINGLE TURBO... ADV or NTK?? - 05-21-2019, 09:56 AM

Hello, I am single turbo 6466 doc race kit. As it is known, oem o2 sensors get cooked in the pre turbo atmosphere.
I have been reserching in forums and someones go into ADV ( by motiv) and others go into NTK.

Adv are sold out , 450usd pair and need some special config

NTK are like 330usd pair, and I think no special config.

Also some people use oem bosch sensor + separator

What is your experience single turbos boys??

Can someone clarify this ???

Thank you

I'm running the doc race kit as well. I went with the ADV's initially and it worked for a short period and then kept having issues. I tried to resolve it with Chris but nothing worked. I'm now using the NTK's and everything is working properly. It's really hit or miss with the ADV's. Some guys don't seem to have issues, where others cant resolve it and NTK's end up resolving it.

Update

I installed a pair of NTKs and one get roasted in 200miles.

Now, I will try a "spacer" that moves away the O2 sensor some inches with oem bosch o2 sensor

Been running NTKs with no issues for 40,000 miles now with zero problems. Started single turbo life with a set of ADVs that gave me problems from the first start up until I replaced them. Motiv sent multiple tunes, but nothing corrected the problem. Swapped a set of NTKs in and everything worked perfectly and still is. Having to tear back into the car to swap o2 sensors after going through all the work of a single turbo swap was frustrating to say the least.

Ntks also supposed to be for pre turbo atmosphere and mine failed after 200miles.
I don't know why they fail , I have seen ntk or bosch in big turbo subarus , audis etc where the exhaust manifold gets incandescent red and they don't fail.

I suppose that there is something else killing o2 sensors. May be external temperature?? By the way, I always kill the same sensor ( bank1). Bank2 never fail and it is also in a "unhealthy " atmosphere.

Can you point me to a part number? Which specific NTKs are you running? I'm looking to get proper O2 sensors for my single turbo setup, Doc Race 6266.

Maybe your EGT is too high? You're doing it right using the extenders and syncs, it's an unfortunate effect of running pre turbo o2. But in response to an earlier post, ADV and OEM sensors should be recalibrated when ran pre-turbo. Factory tables are very off.

Ive seen a bunch of people talking about turning the ignition on (without starting the engine) and letting the o2's "warm up" for 45-60 seconds, THEN starting the engine. A bit inconvenient, but after recently having to replace o2's myself, I'm going to give it a try.

I had stock sensors btw. Lasted about 3k miles.

Updates!!!

New bosch o2 sensor + innovate heat sink.

Do some pulls in 3 geard. From 2000 to 4000 4500 rpm ok..then running lean and misfire.
Another pull and the same. Couldn't finish because the car misfire .
Last pull :
30BA dme internal failure
2C3B lambda probe in front of catalitic converted : not plugged
29CC misfire , several cilinders.
( cil 1 2 3)

The car has check engine now and running in 3 cilinders.
Bank 1 afr stack at 20 ( sensor has 20 miles)

I attached some logs... as i said i couldn't run from 2000 to 6500rpm as the car started to misfire

What do you think?? Could be the tune??? It is impossible to burn o2 sensors as me..and know I have this new issues.

I will have the ecu fixed ( injectors integrated circuits???) Then check cil 6.. (injectors / coils/ spark).

What do you think??

If you want them to read accurately, yes.

You had an injector mosfet fail, and need to check your O2 sensor wiring for burns/cuts etc. Alternately the failed mosfet to back 1 injectors could be why you're seeing those readings, so repair the dme first before spending more money imo. Mosfets are cheap and fix the issue permanently.
