HELLO  ALL ; Has anyone tryed the wide band oxygen sensors over the stock narrow band oxygen sensors ??

 Has anyone noticed if there is any improvement on them in either the performance or the cooling of the motor  , as the manufactures so claims

   THANKS AGAIN ALL , JEFF

Jeff,

You can't do it. The stock sensors are two wire units and the wide-band units are 5-wire units. The other problem is that the ECM software is not programmed to use anything but the narrow-band sensors. It wouldn't know what to do with them if you got them installed.

hello ;  the ad i had seen  , said that they had a wiring harnass adapter that would work and the ECM could be reprogramed...

Here's a couple of pages from Night Rider that might give you some info.

use at your own risk---------what is the extral resistance doing to your ecm??

Should just reduce the voltage, tricking the ECM into adding more fuel. The only problem I see is it's all the time, not just where you really need it. But if your not going for an ECM upgrade of some type, I think a little rich in a few spots would be better than lean and hot.

You can use the wide band sensors 'IF' you use an ignition set up for them or the DTT Twin Scan with SERT for 2008 Touring, which only records data. The latter seems to be a better option then the Auto Tune's. I have used both and much happier with the data record and manual tune using the SERT. But as Chief is saying, you cant use the stock wiring and stock ignition for wide-band units.

how can you get good data using the twin scan logger when using sert on bikes using 2 oxygen sensors? your narrow band oxygen sensors will not be in your pipes, only the twin scan  wide band sensors will be there ?

You might want to look at the thread below, when you make some ATF ratio changes you narrow band O2 sensors are used, the system goes to closed loop.

HELLO;  ALL ,  I have the SE RACE TUNER  on the bike now ,  it  is my understanding that with the wide band o2 sensors and  the adaptable wiring harness    , it all should work when adjusted rite .....  i  was just wandering if anyone had done it yet !!! and if they had noticed any difference  , in either the cooling of the motor and/or the performance ?  thanks

Goliath,

If you have the SERT, then you have what you need to solve the lean running motor. The wideband sensors will not get you anything more. The ECM does not know how to talk to the WB sensors, it only understands the NB sensors.

My suggestion is to leave the sensors alone and take the bike to have the ECM tuned with the SERT. You'll be much better off that way instead of trying to use parts the ECM was not designed to use.

Good luck.

I don't use the narrow band with the twin scan and SERT. I'm using the DTT Wide Band Sensors with the Twin Scan. On 2008 Touring this is the closest option you can get to auto tuning using wide band sensors. Just pointing out the SERT can be used with wide band sensors, IF YOUR USING TWIN SCAN. A lot of people don't like the hassle recording data then making necessary adjustments. I actually like it over autotune because you don't get the fluctuations as you do in autotune and the process actually forces you to learn more about tuning. Besides, i think it's a kick in the arse too.

Goliath, Chief is right on. Best way to understand in layman's terms is NB sensors are basically a on-off switch that work with the Delphi ECM to maintain a preset AFR so they have limitations. Japanese and German bikes that use wide band O2 sensors work with ECM's that accept a continuously variable input to maintain the AFR.  As someone mentioned you can change the ECM that accepts the wb sensors but that is a whole another story. As far as the SERT is concerned, its just an interface that allows you to reprogram your existing delphi ecm. Not to complicate things more but the nb O2 sensors are just one of the inputs into the HD ecm that controls the fuel injectors/ignition.
