Wideband O2 in place of stock?
 

I just purchased a plx m-500 wideband O2 with datalog. Besides the outputs for datalogging, it has an output for linear and narrowband. I was wondering if I could replace my stock O2 sensor with the wideband sensor on a stock TII ecu or just with an aftermarket ecu.

You can replace the stock O2 sensor with your wideband O2 sesnor, and wire the narrow-band output to the stock )2 wire, to keep your closed-loop cruising functional.

now make sure you are not going to put it anywhere near as close to the turbo as the narrow band though or it will eat through those o2 sensors like crazy. If anything leave the narrow band in just unplugged or weld up the bung and place the bung for the wideband further down from the turbo.

Depends what lambda sensor he uses.

My NTK sensor is fine in stock positioning.

the m-500 comes standard with the bosch wideband oxygen sensor.

My NTK (Over three years old), works fine in the stock location or six inches before the left rear muffler. TechEdge equipment from the land of OZ.

I went ahead and mounted my inferior bosche sensor at the front of my midpipe. The NTK is 3 times as expensive.

Quality costs money.

You realise you have started two identical threads with different titles, plus a third thread with a different question about the same unit?

Are you implying the bosch sensor is not quality?

I am not implying it, I am directly stating it. Compared to the NTK sensor, the bosch lambda sensor is lower quality. Its not as accurate (1.5% less accurate), and its failure rate is significantly higher.

If I am paying $1000+ dollars for a wdieband system, I want to use a quality sensor for it. When it comes to tuning cars for other people, I am not going to spare cost at the price of accuracy, and I think my customers would wish that were so.

Its not debated that the bosch sensor is of lower quality, I don;t see why you raise this as a question.

I paid 300 dollars for the sensor with the plx 300. I don't have a 1000 dollar wideband set up.

There's no doubt that the NTK is superior.

For someone who's not tuning their car on the absolute edge, I just don't believe spending the extra money on the ntk will be of much benefit to them, and that's all.

Okie, you guys are being nuts.

My L1H1 sensor came in a BOSCH box. What is stamped on the side of the sensor. NTK.

Bosch does not make NTK, nor vice versa. Your post has no point.

$300? Ouch... should have been closer to $60. I only pay $160 for my NTK sensors.

We agree that the NTK sensor is superior... by accuracy? 1.5%. Pretty insignificant. By longevity... pretty significant. You can place the NTK sensor 4" from the turbo and be fine, while the bosch unit will die placed so close within a few miles, thus giving the NTK a more accurate reading.

I charge my customers for my tuning, and thus they expect the most accurate readings they can receive. For a single customer buying a wideband, its not worth the extra money for an NTK over the bosch.

I understand....I was just noting that my NTK sensor came in a bosch box...some people might think they have a bosch sensor when it was made by NTK.

Oh.

OK.
