What wideband o2 sensors are you using?

[emperor_lunchbox]

I was wondering what eveyone is using for air/fuel ratio management?

and what O2 sensors are you guys using?

also, are they like engine specific?

im kinda new to this so any information is useful.

thanks.

I bought a PLX Devices wideband O2 with display. Can be found on http://www.lsauto.com or on http://www.plxdevices.com

Will put it to use when my rb gets down in the next week or so.

I dont know if this has been done before but i think its really cool with the wireless datalogging!

I think i will go with either one of those. my question is now, what is the difference between NTK and Bosch?I know that NTK was the standard but does that mean it is better?which do you guys prefer?

NTK was the "standard" because that's all there was a few years ago. The NTK replacement sensors used to cost about as much as standard O2 sensors until the manufacturer realized that they had a monopoly. And that's how the $200 wideband sensor was born.

The new Bosch units (there are at least two models with several variations) use newer technology, heat up faster, and provide the same precision. However, they are used on quite a few cars, and are thus really cheap. Depending on the variation you need, it may be only $30.

The difference in wideband controllers is that most of them were designed in the pre-Bosch wideband era and must use the NTK sensor. The sensors are different, and use different heating routines, so the wideband controller manufacturers would have to develop new software and hardware to control the Bosch sensors.

The Techedge 2.0A wideband is a very nice unit with built-in datalogging that saves in its own memory, and later loads into a pc, or can load directly into a pc. It also uses the $30 sensor and is just as accurate as the $800+ units. The prices are great and customer service is awesome, as they are an Australian company and 99.9% of people in Australia rock

plx devices has a wideband o2 sensor that does wireless datalogging for like 510$ shipped, with the bosch sensor. the other kit they offer that has wireless datalogging is like 630$ and uses the NTK sensor.i was wondering if that will make a difference?

This is the best for the money, hands down.http://www.innovatemotorsports.com/

(Yes I have one, and it rocks):D

Keep that speak and spell to yourself lol. I rock the Zextronic wideband with the Display.

im using a plx m-300. got it for $320 shipped from one of our sponsors. it doesnt datalog but it has a great display and works for my on the fly tunning

[goofynick6]

I'd say datalogging is a must if you care about accuracy of tune....and the NTK unit costs more because the sensors are $180, not $30, and there is no tuning advantage with the expensive unit.

The innovative unit makes you buy a $100 RPM thing that allows datalogging of the rpms vs. a/f, which to me is extremely important for a good tune.

i read about the Zeixtronix and the innovative one in a magazine the other day. I liked them both except the innovative was too large and the zeixtronix didnt have configurable software.I am not sure what that means, but i do know that the models that cost more had that feature.

[74260zt]

Thats the key, everytime theirs a firmware/software update, with the LM-1, they give it to you for download via their website for free

I haven't looked into the Zeixtronix unit yet to see if they offer that feature.The dataloging portion wasn't a selling point for me, as I run the TEC2 standalone, so maybe for that feature, others would be a better choice....

[goofynick6]

True, I'm running just regular ecu with custom EPROM, so I need to be able to datalog.

Nick

[emperor_lunchbox]

what difference does running a regular ECU with an e-prom or a TEC2 have on the datalogging?
