Plug-n-Play Fuel Management Upgrade



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


  • Touring  2007-2009
  • Softail  2007-2011
  • Dyna  2006-2011
  • Sportster  2007-2013
  • V-Rod  2007-2011


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


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 the stock H-D 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.


Finally my bike is running right. Surging is gone, heat is way down. -Jason


"409” ignition wires provide continuous heat protection up to 600-degrees Fahrenheit

Customer Reviews

Nice product Review by Jim
I installed a set of these on an 09 dyna with open intake and exhaust. Product performs as advertised. It richened the fuel/air mix and my bike runs cooler and stronger with overall better performance. I feel certain a real tuner could do better but not for the price. Most inexpensive, legitimate way get more fuel when running an open intake and exhaust! (Posted on 8/17/2018)
