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.

  If one takes the time to review closed-loop vs open-loop EFI, etc..,, these are the way to go for a base level upgrade. easy to install, ground wires a bit longer than needed and also seem a bit on the thin side. Engine runs MUCH better, running 13.9 on front and 13.85 on rear cylinders, with K&N RK filter kit, stock 2013 883 Excellent upgrade, most excellent price !

ViED usage
  Installed a basically open exhaust, didn't realize that I'd have to adjust the ECM. So instead of getting a "tune", I just installed these, and leane'd them up a little more than recco'd. Work perfectly, no more pop/fart on decel, and lowers the heat a ton

CVO George
  I have looked at fans, oil cooler fans, and then I found the VIED, XIED'S through your company. I called and talked to who I consider to be the owner or at least the developer of these products and with his recommendation I purchased the VIED for my 2013 CVO Ultra. I had problems constantly with the rear cylinder shutting down on just short local trips through town. The idle was rough and the engine seemed to struggle the hotter the outside temps were....we reach 110 to 120 F here in the desert in the summer. Recently the temps broke and dropped as winter approaches so after I received the vied's I rode the bike in the heat of the day reaching 99 to 102...I know, that is not much cooler. The rear cylinder shut down at the very first stop light I came to and all subsequent lights. I returned home and installed the vied's and set them to 50% and went for another ride. the outside temp was 99 degrees and at first the bike didn't seem much different. As I rode I first noticed the temperature drop on my right thigh. I also started to notice the lack of exhaust popping on decel and in between shifts. As I continued the idle at stop lights seemed to be much smoother and after about 35 minutes of riding it occured to me that the rear cylinder had not shut down at all. I thought I was just not paying attention so I came to the next light....generally a long one and reached it just as it turned yellow so I stopped and waited for the obvious. Almost 4 minutes later the rear cylinder had not shut down. I will ride to and from work this week and then make an adjustment and see where it takes me from here. First impressions are amazing and I recommend to anyone that this is far cheaper than installing fans, oil coolers with fans, although they might be necessary, I think the vied's are the most bang for the buck. Thanks Nightrider!!!

Great item
  I have been running this with a stage 1 air and two into one Rineharts for more than 3 months and 3 thousand miles. It has worked great. The richening of the fuel mixture is noticeable in long distance riding mpg. Any more than a stage 1 setup and you will need to have harley retune the bike or get an aftermarket tuner.
