Plug-n-Play Fuel Management Upgrade



The Plug-n-Play XL-ViED-14 richens the Air Fuel Ratio from14.6:1 to a range of 14.3-13.9:1 in closed loop mode.  

This Variable Fuel management upgrade allows you to fine-tune the air fuel mixture with a small screwdriver.

Immediate Benefits:

  • Lower Engine Temperature
  • Lower Exhaust Temperature
  • Improved Throttle Response
  • Reduced Surging
  • Reduced Pinging


Recommended for:

  • Stock Configuration
  • High flow air cleaner
  • High flow exhaust
  • "Stage 1" (both high flow exhaust & air cleaner)


The XL-ViED-14's are a cost effective alternative to an aftermarket tuner & dyno runs.  XL-ViED-14's will cool your bike down and make it run better.



  • Sportster 2014 - Up Models  

These work great with 2014-2017 Sportsters.  On 2018 and up Sportsters they function just as well,increasing the fuel for better running, less lean condition.  But they do throw a CEL and some codes.  This does not impair the function at all, but it is annoying that the CEL is lit and the codes are logged.

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

 2007-2013 Sportsters use the ViED, XiED or the X14iED


They work inline with the smaller H-D Delphi heated narrow band 02 sensors and Delphi ECM to richen the fuel mixtures, adding up to 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.


I like that it allowed me to fine-tune the AFR to my riding style.  Very happy with the cooler, smoother running motor. -Tim

Customer Reviews

Economical, Functional Review by mike
Fit was perfect, easy install,unobtrusive.Have not put on enough miles to see full results yet, But throttle is crisper and does not surge as much.I set front cylinder at 50% and rear at about 60% Another 200 miles will provide more opinion.But for the moneyi recommend this product.
