I read somewhere that the ability to use a wideband is built into the wolf 3d v4+ system. I ordered a V4+ and was wondering what o2 sensor i have to run to use the wideband option.

or i am just crazy and i read something/interpretted something completely wrong?

kevin.

 

I think you interpretted something wrong. I may be mistaken, but most wideband sensors are driven differently (ld01, vw7057, etc). The wolf can display a/f ratios based on input voltage though. However, last I checked this wasnt working properly.

I use a wbo2 wideband controller with the vw7057 sensor. It has a narrowband output from the box that I run to my gauge and my wolf3d. Once wolf datalogging is setup, I will run the wideband output to it so I can get readings.

 

so basically i have to buy a seperate wideband system? and run that to where?

kevin.

 

basically, yeah

 

Umm Nope.

Wideband works.

Check page 15 I believe it is.

 

It looks like the wolf can only power an lsm11?

 

doing further research, the lsm11 doesn't seem to be a true wideband.

There are however other versions of the lsm11 (pm[military] and rm[race version?).

The wolf isnt really driving anything, the wiring diagram simply shows how to hook 12 volts up to the heater and grounds up to the units grounds (signal ground and heater ground) while the signal wire just hooks up to the wolfs signal input.

I am going to post some more information shortly. This sensor is outdated and not used.

 

this sensor is not a real wideband sensor, as i stated before, the wolf has no control for a real UEGO sensor. This sensor is considered a "wide range" sensor. Output is affected by heat and will not be accurate in the range you are trying to tune to. I would not trust this on a turbo car.

heres some more intersting info, max temp - 800c
max sustained temp - 600c

The lsm-11 was designed to be used from 1-2 lambda.

 

As a follow up, it looks like a lot of people use this sensor. However, it will 1: not be accurate below 11.8:1 and 2, be affected by heat that will cause it to give you a reading richer than your actual A/F ratio. Even if you use this in a rotary, you will be operating it in a range of temperature it is not meant for.

Get a real controller like a techedge or FJO or one of the others. Use a real wideband sensor (I have had great luck with the LSU4. From what I understand/hear the NTK L1H1 is also another reliable UEGO sensor). These sensors are designed totally different from the lsm-11 and will function accurately in different temperature conditions and over a wide lambda range (from about 9.5:1 to infinity).

P.S. Please make sure you research what you post when its something that can possibly be blowing up someones motor. thanks

 

Hmm, very interesting...you da man.

 

Umm in MY post I am simply linking the WOLF Tech document. It lists it as a "Wideband" o2 sensor.. not the end all of sensors.. or what you percieve as the "Best"
I agree with some of the information you posted.. no problem there.

However THE ONLY THING that will blow up someone's motor... is if they are stupid.. and try to tune without knowing what they are doing. Random guessing SPECIALLY on a charged motor.. is asking for trouble.

KK Thanks.

 

I agree the documentation says wideband and I actually sent an e-mail to wolf about that. The LSM11 is not a wideband sensor, its just a more accurate heated EGO sensor. I wouldnt trust it.
