Fits most 2007 and later H-D (except 10 and later Touring, 2012 Dyna/Softail/V-Rod), including 06 Dyna. The ViED(r) is our universal fuel management device. Its variable AFR design lets you set the fuel mixture for any H-D using the Bosch O2 sensor. A very simple adjustable AFR device for your bike requiring nothing more than a small screwdriver. This is based on our simple plug-n-play fuel management upgrade specifically designed for most Harley-Davidson bikes. Nightrider's unique patented design works with your existing OEM O2 sensor and ECM allowing richer fuel mixtures. Riders can quickly and simply richen the closed loop fuel mixture on your Twin Cam, Sportster or V-Rod engine from the stock 14.6:1 to a 14.3-13.7:1 AFR range.
The richer fuel mixture results in benefits that can include:
  • Cooler exhaust temperatures
  • Reduced engine temperatures
  • Improved throttle response
  • Less engine ping
  • Less low RPM engine surge
Nightrider's advanced patented design works inline with the 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 H-D engine from the stock 14.6:1 to 14.3-13.7:1 AFR. The ViED's can add up to 8% 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.
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
  • XL 883, XL 1200, XR1200, Stage 1 upgrade
  • V-Rod
Upgraded exhaust systems including slip-on mufflers and full exhaust changes, and air cleaner upgrades are compatible with the ViED(r) upgrade.

Abiding Dude
  I ordered the ViED instead of the XiED because even though I was just doing slip-ons and air filter because I wanted to make sure I could get the best possible response. I'm just picky. 1. Shipping was fast 2. Installation was easy 3. I think it is working, basing this on decel popping. The engine has to warm up before you decide if popping is bad enough to dick with. I was getting decel popping in 2nd gear. I wrote tech support asking which way to adjust the screw. He responded in less than a day telling me to make it richer. I adusted a little bit and now I get popping on decel from 1st gear. I have not re-adjusted it yet but I'm hoping that will fix it. I do not expect decel popping in neutral.

Works as advertised
  I've installed the FL-Vied on my 2010 FXDWG (stock AC, stock headers, V&H slash cut slip-ons) and tried various settings. Started with 75%, then went to 50, then 62,5 and now it's back on 75. Regardless of each setting, I still can't get rid of all the popping and backfiring, but as promised by Nightrider it's quite a bit less than before. Good enough I guess... I only hoped it would eliminate the popping/backfiring a tad more than it does now. And no, I don't have any exhaust leaks. Torqued everything down to spec and checked several times. ;-)

Great product
  Very satisfied with this product. With an intake and exhaust the ViED has eliminated all studdering and ping during acceleration on my 2012 sportster forty eight. Much more responsive, completely different bike.

I also install a big sucker air filter system a week later still running 25% the bike runs great thank you Steve I believe having your system using the 02 sensors just makes sense works great

VIED on 2010 Heritage Softail
  I bought this for my wife's bike because I put after market pipes and a stage one air cleaner on her Heritage. I didn't want the popping that is associated with too lean of a mixture in the fuel injection. The bike does not pop out the exhaust and the mileage was at 43 miles per gallon after she ran the first tank of gas out of the bike. Good price and a good product for me.
