Re: Possible to replace primary o2 with a wideband?
In Hondata S300 and also Neptune RTP, you can use your wideband input (B6, D12, etc) as your O2 voltage. You just disable your O2 heater, and then set inverted closed loop with the proper input set as your O2.
Re: Possible to replace primary o2 with a wideband?
stock(even chipped) ecu wont know the readings of the wideband sensor since its only programmed to read the lean/rich.
thats what the wideband controller is for. so you can use it to monitor the afr and send the signal to the ecu as a simple ric/lean.
Re: Possible to replace primary o2 with a wideband?
Just a random question. Does aftermarket 4-wire o2 sensors come WITH the plug? The ones on ebay doesnt look like it does. And also, how would i find one that's longer in wire length?
Re: Possible to replace primary o2 with a wideband?
Went through your other thread and the only input I have is that if you're using a stock tach it won't read rpm as accurate as you might think. At higher rpm it will read different from what a dyno, and aftermarket tach will read.
Also if you run an aftermarket wideban you have to wire it into your engine harness o2 wires to read voltage and send that reading back to the ecu.
I'm not sure 100% on what i'm saying it's just what we have experienced.

It wont. You need hondata or obd1 tuning software with emulator and wideband set to output signal to original ecu o2 sensor input. This is not something that can be explained in a single thread. Took me weeks of reading on pgmfi.org to get comfortable with the lingo and hardware back in the day.
Re: Possible to replace primary o2 with a wideband?
i guess i didnt realize how expensive are the O2 sensors. i had to replace mine last year but i know for sure i didnt pay that price i just cant remember where i bought it from
how is a wideband sensor 2-3 times cheaper than narrowband OEM sensor from honda?
Re: Possible to replace primary o2 with a wideband?
That thread helped me out. I just recently got a code 43, yet my fuel pump and filter are new. I've never changed my O2 sensor, yet it has some exposed wires.
Will driving with a bad O2 sensor cause any damage. I just bought a new header and plan on replacing it next month when I order a new catalytic converter.

Most decent widebands have a simulated narrowband output, you can feed the signal into a stock ECUs so they do not set a code. I've done this for many years. To read the Wideband signal I simply look at the gauge when I want a reading.
A simple chipped ECU operates the same (if closed loop is enabled)
You can disable the O2 in what ever program your ECU is chipped in and run the Wideband signal into the ECU. this will make it possible to log the wideband but if the maps are not perfect you run the risk of running rich or lean without the saftey net of the O2.
You can also purchase a license to run eCtune or Neptune via emulator (ostrich or Demon) and run the wideband signal into the ECU directly.
You can also use above software to run the wideband signal into another analog input of the ECU.
I've run all of these setups in one way or another and the main advantage of feeding the wideband into the ECU is the logging ability. If you're simply curious and want to know what's going on, the narrowband output setup of a wideband works perfectly.
Re: Possible to replace primary o2 with a wideband?
11 has to be chipped
2 has to have datalogging pins in the cn2 port part ofthen yes but to change it a emulator or a burner
Fatalog see the difference in afr % and add it on to the section it's in BM tune uses the Ostrich protocalls I think so works just like it COBRA RTP $ 200 v3n 4
BM tune emulator $120 does everything sopoze too
Rely it's haven one these programs to change the settings to and u can HTS BM TUNE free downloadable and work can data log with simple rs 232 cables
Re: Possible to replace primary o2 with a wideband?
Depending on the type of wideband system you have, some has the option for you to run a 0-1V signal to the stock wiring. This means you can double it as a narrow band. If not, you'll have to run two o2 sensors, and yes - this would mean you'll need two o2 bungs installed.
I know that the AEM wideband only has one output wire that you could either send a 0-5V or a 0-1V depending on the setting you set it to. The 0-5V can be sent to standalone ecu to be used for closed loop operation; 0-1V can be used to simulate a narrowband.
If you don't have a standalone ECU that can use a wideband signal for closed loop (they all should be able to), I would run a second o2 sensor - your mpg will likely suffer combo with poor partial throttle response.
If you are replacing a stock O2 sensor with a WB O2 Sensor. You should be able to hook the stock heater wires up to the WBO2 sensor heater wires. Most WBO2 sensors have heaters as well. Not to mention if you are running an aftermarket EMS or chipped ECU you may also be able to disable the O2 Heater CEL.
