Wideband O2 options?

[turbo98_240sx]

Ok I'm in the market for a Wideband (finaly) And wanted to know witch ones all ya felt was a good bang for the buck, I won't need to datalog it cuz its going to my e-manage but it will need a 0-5v output. I don't want a LM-1 cuz to me there too much $$ for what you get IMO, I don't need anything fancy cuz I'll prob just tune w/ it and take it out as appose to something that I leave in and has a display that is really nice or something. Any sugestions or even a DYI thing wouldn't be so bad if its on the cheaper side and can output 0-5v. Thanks for your help with this, oh I'm not looking to spend more then $200 but then again I know you get what you pay for so maybe as much as $300 for a nice one, or if you know someone with a used one that would be even better. Thanks again,Pat

i've been eyeing that one for a while. im thinking about getting it at some point

[turbo98_240sx]

I too have been eyeing that one and kept it in the back of my mind but how Important is EGT to the KA and tuning? cuz I like the price for what you can get and thanks for the quick response

[dsylvia]

i feel EGT is fairly important with any turbo car. Although wide band is prolly more important.

I was able to get a good deal on a stewart warner EGT gauge and themal coupling unit off of ebay for $50.

i'd personally like it seperate but thats just me. it's prolly sheaper to get it all on one in that unit. cant hurt, knaw mean.

hey thanks for the link I didn't know that kit existed

Analog Wideband Output 0 - 5V

^i wonder if that could be used to plug into the stock O2 sensor wire to replace the stock o2 sensor....

My LM1 came in yesterday. I also ordered the RPM converter.

Im going to tune my fuel map to 14.7 at vacuum, 13.0 at 0 psi, and 11.9 at 7 psi.

The RPM converter is going to save me a ton of headache since it will allow spot tuning. That alone is worth the $429 that I paid for it.

if im not mistaken the stock 02 sensor only reads a small area of the spectrum, a wide band reads a "wider" area of the spectrum which is more accurate. therefore using the stock 02 sensor would be pointless.

you would want to use the simulated narrowband output to replace the stock o2, i did that for a few months and it worked fine. the analog wideband output is more for standalones.

you can do that and get a simulator for the signal to the ECU and just use the wideband to tune the car, but then you would have to keep the wideband in there to monitor the a/f yourself but it is do-able

I guess I should have slowed down and read it all; I just noticed that feature

I would prefer to just replace my stock o2 sensor and not have to weld another bung for the wideband sensor which is why I was looking into that as a key feature.

[turbo98_240sx]

any other sugestions? and thanks for all the help so far this might turn out to be one of the better threads for the noobs hehe j/k kinda

Yeah but I already have the greddy kit witch came with the e-manage so I'm gonna use the secondary MAF input to log the O2 sensor so I don't need any kinda data logging if I didn't have the E-manage I would prob get the LM-1 but its a lil expensive since I don't need all that and I'm going for bang for buck cuz I'm ballin on a budget

It would be nice if they had one unit that would read and display:BOOST / vacWideband O2Timming

Those are like the 3 main things that need to be watched while under WOT....

[Florida240sx]

Hmmm so it would cost 400 for the kit.With the lcd screen..

[turbo98_240sx]

Yeah But I'm betting that I would spend the extra $65 to get the EGT probe, but since I'm useing the E-manage to control boost I wonder if I could input the boost signal to the zextronix display. cuz under those circumstances I would wait a month or so and prob fork over the $491 for the package w/ the screen thing and a bung and EGT prob. but thats only if It can sort out the boost signal from the E-manage, Witch I do belive that it will but I'm gonna double check to make sure. Also I'm thinking I might get the bung and tune it in the stock o2 location and just fake the signal to the ecu but I'm not sure yet because I might just mount the thing permanent and buy something to fake the stock o2 signal or does anyone know where they sell those things I couldn't seem to find it in a search so if anyone knows thanks in advance

[Florida240sx]

You can't splice the wire?I'm knew to this 02....Looks like you can tune multiple cars just need the $60 bosch 02 sensor.

theres no reason to fake the stock signal when you can just use the narrowband output for the stock ecu.the zt-2 uses a 3.5bar map i believe, do you happen to know what the e-manage uses?

No way. Widebands need a controller.

Widebands are expensive. No other way around it. You can go cheap, but, it will be at the sacrafice of options.

Beleive me, Im cheap. If I spent $429 on a wideband it was the best option at X amount of cost.

[turbo98_240sx]

JRL I think what Florida240sx was talking about was just getting the extra harnesses and a spare wideband and using it to tune it and then puttin the unit back on his car, but not using it for keeps just to tune, well thats what I though on second glance it does look like he worded it funny tho so I can't tell but you could just swap the control unit from car to car for 37buz or whatever, if you check it out they even say something like that in the description of the spare harnesses

Skatanic28, I belive that the greddy unit uses a 3 bar (above) absolute sensor but I would have 2 double check that

Edit: I e-mailed them zextronix about a page of questions so I'll post the reply when I get it and maybe my letter if its needed to understand the reply!

Yes EGT is pretty descent, but u cant tune nor rely on it... Especially is the timming gets thrown off... Then u will have one large or several large fireballs heading right for that probe which will make that temp go sky high.. Then ull think that ur running extremely lean, which your NOT...

The wideband is more important and the best to date for tunning purposes as most of us already know what...

That looks like a really good deal. Anyone using it yet?

I guess I mis-understood Florida240. Yeah you can tune several cars with the same sensor. Leaving it in the same car all the time is a bad idea anyway. Tune your car and take it out.

EDIT: Didnt notice that the LCD was a $100+ option. Might as well go with the LM at that point. Without it though its a good deal.

if thats the case, the scaling will not be the same between the sensors. good call on emailing them, they have always been really helpful for me.

ive been running it for about 8 months now, no problems. about the cost thing....i find the zt-2 much better for monitoring than the LM. maybe with that new display/gauge they have that will be much better.
