Hi All,

I have a 2006 Dyna Street Bob (International model) that doesn't have any O2 sensors. Recently I installed a Power Vision unit and on the first ride I got an Engine problem indication (the Little yellow engine indicator on the speedo console).

I checked the DTC error codes using the Power Vision and saw that I got two errors: that the Front and Back O2 sensors are not responding.
I wasn't surprised... there are no O2 sensors on my bike. I tried turning off the "Closed Loop Option" using the "WinPV" and the "Quick tune" but now success - I ride for 5 min and Vwalla = DTC error .

Does anyone have an idea how to stop the ECM from trying to communicate with the ghost O2 sensors? or has anyone encountered a similar problem?

Thank you!
Adam

 

Just a guess but maybe the map you flashed was for a bike with O2 sensors so the ECM is now looking for them.

If so, see if there is another map you can use from a bike that doesn't have O2's.

Just looked at a stock 2006 Dyna PV map and maybe what you need to do is under the Environment Tab, choose "Closed Loop Minimum Temeprature" and set it to 310 degrees like the instructions say. This takes it out of closed loop so it will not be looking for O2 sensors.

Also, you should likely post this in the Sticky Power Vision topic at top of this section where all the PV experts hang out.

 

Thanks for the help!

I noticed that my WinPV software was out of date so I didn't see the environment tab.
I modified the minimum temperature as you (and the instructions stated) and I'll test it tomorrow.
For some reason the max value is 239 C. I think that will be enough

Much appreciated!!
I'll also look for the Sticky Power Vision topic to post there.

Cheers!

Change your cruise range AFR from 14.6 to 14.2, that will turn off closed loop and will take care of the error as well. This will also provided a better target AF for running without fuel correction.

 

Hi uscanuck,

Don't know why but your solution didn't work. Damn DTC light keeps lighting up.

Thanks for the comment FuelMoto,

Will this setting work with my Setup?
- Arlen Ness Stage I Big Sucker air filter.
- Python 3" Mamba Slip-ons

Thanks again!
Hope it works tomorrow!
