Single Turbo peeps... what O2 sensors?

[Scorpstan]

the only sensors what will work are ADV pre turbo sensors.

BOSCH ADV PRE-TURBO O2 SENSOR

Bosch ADV Pre-Turbo O2 Sensor Please Note - use of sensor(s) require you to splice onto an old O2 harness as the ADV's are not available with the correct connector. THIS ITEM IS NON-RETURNABLE

The only sensors?

That's a wild stretch considering I have a lot of miles on NTK, denso, etc. As I said before, ADVs work for some and don't work for others, with zero explanation why. And they seem to burn out in a few years which makes them no better than any regular O2.

With all the table changes required in tune, inconsistency, etc. I do not consider them a viable option. And I don't care what any company that stands to profit from selling the sensor has to say on the matter.

It's not about what a company says, but that Bosch, denso or ntk are just the wrong sensors.

The normal lambdas are not suitable for high temperatures and especially not for high pressures.
This falsifies the afr bet and sooner or later the normal sensors will break.
Regarding changing tables, I don't know what should be so difficult. This is just a click via the mhd app.
I can not understand that some people have problems, but maybe that's because these people took normal ADV and not ADV Pre turbo, or forgot to put one wire of original connector away, or don't flash the adv tables via mhd.

Here are Pics. One with new NTKs and One with ADV Pre turbo Sensors. Last much smoother!

Imagine lecturing a group of single turbo guys who have spent years trying every o2 combination out there in 2020

I ran NTKs at 36 psi on my old setup, AFRs were verified against the dyno wideband using nothing but JB4's built in model for EMAP lambda correction.

If that isn't good enough or you're flash only there's pressure compensation tables which will let you do the same or better. All of this using sensors that technically do not belong pre turbine but are made to work with some tuning tricks.

Please go on lol your love for ADVs is quite amusing given their less than stellar track record.

I think people's experience will depend on the manifold design. It seems to me the speedtech has been good for the O2 sensor market, so if anyone had some input worth considering I think it would be them. I have ADV sensors but my manifold is not the same as everyone else aside from a few, I have the ADE ram horn style manifold. It's been one of the completely trouble free aspects of my car, including the sensors. Never checked or changed them. Full disclosure I've only got like 6k on my kit in the last few years.

best chance of success regarding ecu dummy spits - distance from exhaust port to sensor needs to be the same as each other and as similar to oem as possible.. this is a separate issue to temperature / pressure etc. I'd wager the that the top mount guys are having more problems than the short runner bottom mount guys (which would be counterintuitive from a heat point of view) maybe a survey can be done on that - "are you top or btm mount, do you have have wideband issues?"

This is the manifold I have:

I've never noticed any issues with my primary O2 sensors. I had a secondary O2 go haywire, but that is because I had a problem with my flapper valve which is on the same fuse as the DMTL and the O2 sensors I th ink.

Can't stress that part enough. Very few tuners address this.

I've been running ADV's in a speed tech with a GTX3582R gen II now for almost a year with no problems, they work great. 30 PSI to redline, straight E85 with PI, 12.5 AFR high RPM WOT.

32k on my ADVs from speedtech, no issues to report.

Selling my 02 harness jumper because its all getting parted out (no splice, better signal) if anyone's interested.

Figured out the whole 02 in the downpipe thing... just needed to put a 2j in there.

 

[dmacc]

+1 for ADVs. They fixed my deviating AFR's on my speedtech kit.

This manifold uses the O2 sensor venturi/heat sink which is recommended for placement of the sensors pre turbo, maybe that's why they are trouble free.
