Simple install-comes with instructions.  No tools required, installs in a few minutes.

A Technical Update:

The 2012-13 Sportsters, especially the 883, seem to do a bit better with the XIED's.




HD has changed the fuel maps due to emissions regulations. This has resulted in the 2012-13 Sportsters really liking the extra 2% fuel the XIED provides over the X14iED.




Not that any of the 2012-13 Sportsters will run bad with the X14's, they just respond better to the slightly richer XiED's.




2014-16 Model Update:

The FL-ViED-10 is the best product for all 2014-16 Twin Cam models. 

 2014-16 Sportsters use the XL-ViED-14

They work inline with your existing H-D Bosch narrow band 02 sensors and Delphi ECM to richen the fuel mixtures, adding approximately 6% more fuel to the engine in closed loop mode.

There is an indirect richening of the open loop fuel mixtures through the learning mode, or adaptive fuel value action built into your ECM.  This ensures the richer 13.8-12.5:1 AFR's are ALSO adjusted in heavy/full throttle operation.


With my SE Slip-ons and SE Air Cleaner and a HD Stage 1 download, my 2010 Nightster was still running hot and hesitating at low speed acceleration.  5 minute installing the X14IED's fixed all that.  Fantastic Product! -Matt
