Does anybody happen to know if the Nissan ECU will recognize Wide Band O2 Sensors? Meaning If I replace one of my o2 sensors with a Wide Band O2 Sensor will the ECU pick it up? The reason I ask is because I'm trying to get my ODB II software / tool which is equipped with an A/F monitor feature to work properly. However it only reads from Wide Band O2 sensor data. I've already contacted the maker of the software and he informed me that the software requests the O2 sensor data by asking the ECU what sensors are supported. If the Maxima ECU can recognize the WB02 sensor as such then the software would read it. This is the Harrison OBD II software / tool that I'm referring too. Any help is appreciated.

 

tap and weld the new O2 sensor in your y pipe

 

it might, but it probably wouldn't be able to understand what it's doing.

a regular O2 sensor basically has rich and lean.... there's a VERY sharp line built into the calibration so there's no ramp-up on the voltage from rich to lean. one sees about 1V on the ECU, and the other sees about % or 12 V (depending on the system, ecu, etc).

That translates to a logic high and logic low to the ECU, so unless the ECU has an A/D convertor in it specifically for the O2 sensor, I doubt if the WBO2 will do any good.

The other issue is that WBO2 sensors don't last very long. it would NOT be smart to put one in the car permanently. they have a lifespan of only a few hundred hours of use.. that means for a $300 sensor, you'll probably only get a year of use out of it. yeesh.

 

Try it and find out.

 

I'm very doubtful the the ECU would recognize it but stranger things have happened, never say never.

I have the Harrison OBDII as well and purchased the WBO2 from Tech Edge. Haven't tried it out on the Max yet because its now back to stock until I buy another one. It has a digital readout plus Palm and PC logging capabilities. Also has RPM, EGT etc inputs.

However, we did hook it up on my Son's Talon on Sunday and managed to pull a few more HP of out it at the track so I can hardly wait to get it hooked up on the Maxima.

Still need a S-AFC or similar to change the A/F once you know what it is.

PS The other issue that Matt brough up about the wideband sensors longevity. The WBO2 from Tech Edge uses a VW sensor that is wideband but used in high accuracy mode vs the Honda L1H1. The bottom line is that you get the accuracy and you can use it all the time because its not prone to failure like the normal wideband sensors. Even if you do have to replace it they only cost $28. I plan on running it all the time, just because it looks pretty.

 

So Jime would you recommend the WBO2 from Tech Edge? I've considered purchasing this unit however I haven't talked heard from anyone that has used it. Out of curiosity how did you hook it up to your's son's Talon? Basically I need something that's reliable enough to monitor the A/F ratio so I don't have to go to the dyno all the time. I went this weekend to only find out my car is running very lean. I just reinstalled my Apexi SAFC II so I need to fine tune it a bit. The whole point is to be able to this whenever I need to without scheduling dyno appointments and paying the $125 an hour fee for tuning.

 

the new Innovative unit is getting good reviews..RPM logging comes out in 2-3 weeks! Ordering mine next month...only about $330...$99 more for the RPM "link up"(when released)

I think it would now be a good idea for Harrison to offer an optional external WBO2 connection fo enhanced data logging.

I wonder how long it will be before there is a WBO2 for each cylinder.

 

Nice find...I haven't seen this unit yet. Thanks for the info. I may end up getting this after all...

 

Put your farkin SAFC back in and head back to the dyno.

 

You have to have an O2 bung welded on, preferably at the Y or shortly thereafter to get both sides of the engine. We both had one welded on our cars.
Main reason I want one is that I want to tune on the road or track vs the Dyno because they don't load the same, plus I don't want to pay if I do go to the dyno.

BTW I steered away from the Inovative unit because the RPM wasn't even released and its useless without that. Plus you have to pay for every extra like $100 for the RPM, the Tech Edge comes with all. Tech Edge is approx $360 with everything except the sensor which is $28.

 

The SAFC is back on....If you would like to give me the $125 for the hourly dyno tuning then I'll head back!
