Ready to install new Cobra exhausts and need to know for sure if it is ok to plug the o2 sensers? FP3 for tuning and no idea if a map exists for a 2012 Heritage 103 cu in engine.

 

You don't want to plug the O2 sensors, the bike will use them for auto-tuning. There are plenty of maps out there for Softails with a 103 that will get you in the ballpark..

 

THANKS after the bike is tuned should I leave them in or can I take them out?

 

Just curious, what do you think you would accomplish by taking them out?

 

Actually not sure just my nature to ask a lot of questions. Thanks for your help.

 

They work continuously on a stock bike and will continue to do their job after a tune, so leave well alone!

 

i would think they work the same as in a car, they keep your fuel ratio right, not to rich and not to lean. take them out and i would think you would be all over the place, youd have nothing to detect how the fuel is burning.
