I went to a emerging technolgy's class with my work the other night and they went over a new oxygen sensor that dosn't have swings and holds a constent varable for how much oxygen is in the exhust. Do you think they are going to have a conversion kit for older cars? Does anyone elts have any info on this?

If you were wondering its actully 2 oxygen sensors in one that has a controll air chamber in the middle and they measure how much voltage was required to match the air in the exhust by bringing in oxygen from atmospheric air.

Why do you want to convert to the new one? The new sensor will cost over $300.00 each. And the signal is totally different than the ones that our DME is looking for.

i was just wondering if it was ever going to be a possibility. seems to be a possible mpg plus, small power gain... just thought i would thow it out there

the computer system wouldn't be compatable with the signal of the newer sensor, actually it's not the sensor that swings the mixture it's the computer, the sensors we use just make current up to 1 volt depending on how hot it is and the computer uses that to estamate mixture

You are refering to a wideband O2 sensor, they have been used on quite a few new cars for the past 5 years. Even the turbo VW Beetle uses one.
Due to the fact they are in mass production, you can get the sensor alone for around $50 USD (or lower! )
Here is a place with a low price on the Bosch 021-906-262-B sensor

OXYGEN SENSOR, Beetle, 1.8L, Front 01-04 $38.05 (http://www.1stvwparts.com)

Check out this partial list of cars using a WB O2 sensor (http://www.forparts.com/BoswidebandO2app.htm)

The sensor is not directly compatible with a narrowband (nb) sensor. To use the sensor, you need a microcontroller to accurately control the pump current. One of the best wideband Air-Fuel ratio gauges you can buy (at any price) is the Innovate LM-1. It also has a synthesised narrow band output that you can feed into your DME in place of your regular O2 sensor. This is one of the wideband meters I use for tuning cars.

You can be up and running with one of these for around $300 USD, just 3 or 4 years ago you would be spending over $5K for something with the same accuracy.

Great info!

all i was saying is it seemd to have potential to save fuel and a tad more power... i knew that it wuold need a microcontroler jsut like the maf
