wideband o2 sensor

[Limbo]

Just wondering if a stock ecu will hook up to one?
I've got a PFC and was thinking about getting one so that i could hook it up and also adjust my cruising A/F ratios. Looking at getting some better economy out of my little sucker.

I've normally seen most people hook them to an A/F reader of some sort.

Now if you wired the wide band sensor to the ECU would i be able to read it like normal? I have a hand controller for PFC if your wondering

Just curious more than anything

Nope... coz the ecu can only comprehend signals between 0-1v

[whtcrx]

No!

you cant do that, you'll need a control unit of somekind.

Stock ECU, (will read past 0-1v) but will CEL past a certain range.
WBo2 sensors have 0-5v resolution.

Take a look at http://www.wbo2.com - Australian Site and developers of many O2 systems.

Most widebands these days come with 2 outputs off the controller

0-1V narrowband,to keep the ecu happy

0-5V wideband for tuning,logging etc

Im not sure what the pfc can take as far as inputs,but this is how i have my s300 setup.

yep pretty much all techedge (wb02.com) stuff has 2 outputs. seems like good value

CRXer, yeah that was what i was looking for. I'm assuming that the PFC should be pretty close to the s300 on input signals, as both read normal signals.

Got any other info on the wideband that you got?

Also do you know if it is still accurate with the the s300?

powerFC wont read a wide band single only narrow band, where as Hondata will read both wide and narrow at the same time, this is one of the many reasons why we upgraded from powerFC to Hondata for the turbo Integra I built.

this might be slightly unrelated but emanage blue/gold reads wideband too incase someones wondering out there =)

bugger

ok figured it out now.
The PFC can run a wide band O2 sensor but it needs to be run with a datalogger.

For those who would like to know more here you go.

I thought that might have been the case with pfc.

Im just using the haltech setup,its a direct ripoff(rebadged) of the innovate LC-1 controller (http://www.innovatemotorsports.com/products/lc1.php),heaps of support available online for the innovate shit + free software downloads(havent checked the haltech website yet,i just went straight to innovate).

You can get it here (http://www.tweakit.net/shop/product_info.php?products_id=1005) from tweakit(they used to be traders on here,but seemed to have disappeared from the list) for about $300.

It is very accurate with the S300(dont use the ELD input btw,for anybody reading this,it throws off the A/F's by about 1 full point).Had a little comparison test to a tuners wideband on the dyno with it.

^^ It probably wasn't wired up corectly.

I'd support Australian Made in this case - techedge products are world class.

R u talking to me?

Yes De Niro :)

just re-read your post about the ELD input.... I didnt know that, I guess that just another one for the bug list :)

haha,yeah the ELD input puts a voltage offset onto the wideband(hardware problem),could prob be fixed internally,but i found the EGR input worked straight off the bat for me,so no need
