A simple, adjustable AFR, plug-n-play fuel management upgrade that fits 2010 and later Harley-Davidson Touring motorcycles, and 2012> Later Dyna, Softail and V-Rod. The FL-VIED-10 needs nothing more than a small screwdriver to fine tune the fuel mixture on your bike.
The FL-VIED-10 can be used on stock bikes, or those with upgraded exhaust and air cleaners.The FL-VIED-10 is recommended for motorcycles that have full exhaust system upgrades or stock exhaust headers with catalytic converters removed. The ability to fine tune closed loop the fuel mixture based on your upgrades make the VIED a universal installation for Riders. You can quickly adapt the mixture to your upgrades and riding style using a simple screw driver.
Nightrider's advanced patented design works inline with the heated Delphi narrow band O2 sensor and Delphi ECM to richen the fuel mixtures. Riders can quickly and simply richen the closed loop fuel mixture on your TC96/103/110 engine from the stock 14.6:1 to 14.4-14:0:1 AFR. The XiED's can add up to 6% more fuel to the engine in closed loop operating mode than a similar unequipped vehicle. There is an indirect richening of open loop fuel mixture's through the learning mode or adaptive fuel value action, ensuring these richer 13.8-12.5:1 AFR's are also adjusted in heavy/full throttle situations. This richer fuel mixture results in benefits that can include:
  • Cooler exhaust temperatures
  • Reduced engine temperatures
  • Improved throttle response
  • Less engine ping
Recommended for HD bikes with OEM emissions downloads. These include:
  • TC96, TC96 Stage 1
  • TC103, TC103 Stage 1, TC103 Stage 2
  • TC110, SE CVO 110
Upgraded exhaust systems including slip-on mufflers and full exhaust changes, and air cleaner upgrades are compatible with the FL-ViED(tm)-10 upgrade.

Finally runs well in hot weather
  Knocking and pinging that usually surfaced in the hottest temps were finally alleviated with the FL-VIED-10. Two up ride in 90 degree plus heat, had no problems during 750 mile ride.The VIED worked well at reccomended setting. Bike is de-cated with SE air cleaner. Previously used competitors more expensive product-V&H, which was problematic. Eliminated that and very now pleased with Xied product.

2015 Low Rider
  Great product, and a good example of the wisdom of Occam’s razor. Sometimes the simplest and least complex approaches are the best. That is certainly the case when it comes to the FL-ViED-10. I had just bought my first Harley and was very disappointed with its rough ride and the capriciousness of the throttle response (and heat). After some investigation, I came to strongly suspect that it had to do with the leanness of the fuel mixture (thanks EPA for more Stalinesque bureaucracy). I researched options and even went to the local Harley dealer to see what they could do. I guess, legally, their hands are tied, unless, of course, you do a stage upgrade or two with new pipes, intakes, cams, and who know what else. Then they’ll gladly take your money and dyno the bike so that it runs like a top. Ka-ching! But for those of us who just want to keep it stock, we’re left hanging. This kinda sucks, considering what this bike cost. Then my Googling brought me to this product. I took a shot. The premise of how it worked seemed to make sense, enough for me to part with some cash. Verdict: I’m really really really really really really really really really really happy with this product. Now my bike runs the way I was expecting it to when I first bought the bike. I came close to trading it in and going back to Kawasakis.

Second Bike
  I originally purchased the VIED for a 2015 Street Bob that had an aftermarket exhaust and a intake with the screamin eagle race tuner. I installed the VIED and it made it run even better. Long story but I traded the Street Bob in for a 2014 Switchback. Of course I took the VIED off and put it on the Switchback. The Switchback has stock exhaust and air box. It runs so well now I don't foresee getting a tuner with different exhaust because it has the power and performance. Wish I would have known about this before I put the money in the Street Bob. Happy, happy, happy.

Love the FL-VIED-10
  Just love the FL-VIED-10 that I purchased to accompany the slip-on V&H Twin-Slash 3" mufflers and Arlen Ness Stage 1 Big Sucker air cleaner installed on my 2014 Harley Davidson Fat Boy. The product works perfect. Have it set at 50% on both the front and rear. The bike runs perfectly. Everything that I read about the product in reviews and on blogs was dead on target. Love the company and its wonderful web-site, too. This is a perfect & economical way to improve performance with a Stage 1 upgrade for sure.
