This is not for HARLEY-DAVIDSON. This is for non-standard applications and upgrades. Fits all narrow band O2 sensors including 1,2 and 4 wire oxygen sensors. The ViED(tm) is our universal closed loop fuel management device. Its variable AFR design lets you set the fuel mixture for any narrow band O2 sensor.
A very simple adjustable AFR device for your vehicle requiring nothing more than a small screwdriver. This is based on our simple plug-n-play fuel management upgrade as extensively used on Harley-Davidson motorcycless. Nightrider's unique patented design works with your existing OEM O2 sensor and most modern ECM's allowing richer fuel mixtures. Users can quickly and simply richen the closed loop fuel mixture on your engine from the stock 14.6:1 to 14.3-13.7:1 AFR range on most engines. The richer fuel mixture results in benefits that can include: cooler exhaust temperatures, reduced engine temperatures, improved throttle response and less engine ping.
Nightrider's advanced patented design works inline with the narrow band O2 sensor and your ECM to richen the fuel mixtures. Riders and Drivers can quickly and simply richen the closed loop fuel mixture on your 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 typically 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
Reduced low RPM engine surge
Universal VIED's are sold EACH. Wiring these units into your vehicle requires cutting OEM wiring. We recommend cutting the O2 sensor wiring rather than the OEM wiring harness. The O2 sensor is less expensive to replace than a wiring harness. Nightrider.com Performance Products cannot guarantee the results of this product because some ECM's may react erratically to the change in bias voltages. Historically most ECM's have reacted as expected when installing VIED's. But how any manufacturer programs their ECM remains something Nightrider cannot control.
