Plug-n-Play Fuel Management Upgrade



The Plug-n-Play FL-ViED-10 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 FL-ViED-10's are a cost effective alternative to an aftermarket tuner & dyno runs.  FL-ViED-10's will cool your bike down and make it run better.


  • Touring/Trikes 2010-2016 (including the Twin-Cooled Models)
  • Softail  2012-2016
  • Dyna  2012-2016
  • V-Rod  2012-2016

Note:  It is recommended that bikes that have full exhaust system upgrades, or those with the catalytic converter removed, use this FL-ViED-10 product.  Fine tuning of the O2 sensor signals may be required to optimize the fuel mixture when the catalytic converter is not in place.


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


2014-16 Model Update:


2014-16 Sportsters use the XL-ViED-14

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.


"The 'too lean' hesitation at start off was gone. Also gone was the decal popping. Using my highly calibrated dyno-ass I could feel a tad more pull at low end.  

Overall I'm happy. So happy that I'll be ordering another set for wife's '14 Tri-Glide" -Screwball


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

Customer Reviews

Well worth the reasonable cost Review by T103
Easy install. Very good instructions for installation and use. I’ve used them on other bikes and they definitely smooth the throttle operation and help enrich the fuel mixture. (Posted on 6/12/2019)
