Wideband AFR Meters

[B-Man]

Anyone used any of these ??

There this Aussie one - from Tech edge

http://wbo2.com/

AUS $490 in kit form

AUD $700 pre built

(included Bosche WB O2 sensor)

There's this one - LM-1 Air/Fuel Ratio Meter

http://www.innovatemotorsports.com/lm1.php

US$349

Then there's the TurboXS one

http://www.turboxs.com/Tuner/tunerfeat.shtml

$US549

OR has anyone else had experience with other brands ?? (inexpensive ones - not the $1500+++ Motec etc ones)

Cheers,

I was looking at the LM-1 Air/Fuel Ratio Meter, and was thinking about getting one...but have to get my engine probs sorted first.

I suggest staying away from the WB02 meter, i have read bad things as far as accuracy goes

Would I be correct in saying that you would have to use these as a tuning tool only if you have a standard ecu?

What I mean by that is that you would have to have two o2 sensors? The standard one to do its thing with the ecu and the wideband one just to view your air/fuel ratio?

Because a wideband sensor will not work with a standard ecu. Well it dont work with mine anyway, I run without a o2 sensor fitted at all.

FAT - you are correct - I'm looking at one for a tuning tool. Not to connect up to my ECU.

heard great report's about the motoc ones I believe there are also some good ones in the states for much better prices

Ive got an older type bosch lambda metre that i use for circuit racing and find it a great source of information and a long with an oil pressure guage would be a must have in big doller skylines being used on the track . Definatly saved my EJ20 when the fuel pump was about to die as the mixtures started to lean quickly and i just took my foot out of it. Word of caution however only the big doller ( ie motec) sensors have heat correction as i found with mine after 3 laps it heats up and reads a leaner figure but as soon as you cruise it for half a lap and reapply the throttle mixtures are correct again .

Sadly Motec=pricey.

One thing which i wouldnt be too concerned about is if they have temperature compensation. Great if they have it but word of mouth has it isnt critical for accuracy.

This idea didnt go down too well, http://www.skylinesaustralia.com/forums/sh...highlight=money

i have the lm1 type from the usa... have compared it to the dyno af metre and its pretty dam close.....i would have no worries about tuning a car with it .. safe as all the other more expensive ones... has datalogging and good software....

cheers...

Good review on the LM1 Mark.

I was thinking of getting this a few months ago, but wasn't sure on the capability with the Datalogit.

Are you using its own datalogging feature, or have you hooked it up to Datalogit...?

[markr34gtr]

at present just its own datalog ... i believe datalogit is hard to get all the settings right between the two units.. going on what people on the datalogit forum talk about...

but lm1 is pretty cool for the price...

my car runs 11.8 af on the dyno and the same on the road with lm1 in the tail pipe....

so i am happy..... and its fast acting about 10 or 20 times per sec i believe...

the only thing i dont like is the small lcd screen but if you have a laptop its no worries...

cheers....

hi there, I brought, built and use the techedge meter. Its very good, very accurate (compared to the high speed AFR on a dyno dynamics dyno (in fact it uses exactly the same bosch sensor)) and I run it into my PFC datalogit program. Its awesome and allows on road tuning and full datalogging of all your runs When used with the datalogit program of course.

I would highly recommend it

thats what i found on the website.

[funkymonkey]

that's wierd, was reading a japanese article on wideband O2 sensors and they actually rate the WBO2 as good as the grid unit.

[carl h]

the older wbo2 wideband controlers had to be manualy callibrated from what i can gather off of the website but the new ones are spot on now with the big money ones.

ive got a friend who tuned his car with one and then dynoed it and afr's were spot on, ive one on the way here stateside for my car when i swap the rb20 in.
