How to Richen Closed Loop EFI

Building an inline enrichment device 

A narrow band O2 sensor (NBO2) is normally intended to only understands a 14.6/14.7:1 air fuel ratio (AFR), providing feedback to the ECM to richen/lean the fuel mixture as the AFR drifts off center. This information is useful on a wide variety of motorcycles and automobiles using narrowband O2 sensors. 

NIGHTRIDER.COM(tm) and Stephen P Mullen have experienced several companies/web sites taking advantage of its good will towards individual Riders and making copies of its Patented product for commercial gain. We no longer provide this technical information for personal use.

 

The XiED(tm) and ViED(tm) inline enrichement devices are "Protected by U.S. Patent Number 7,805,236".

Companies and individuals building these devices for commercial gain are in violation of US Federal Law and International WIPO Treaties. 

Nightrider.com is developing its patented narrow band O2 sensor richening technology for several new motorcycles. In addition to current Harley-Davidson and Buell models, the XiED/ViED technology is being developed for Ducati, Victory and Triumph. We will be offering free test versions of the Ducati and Victory versions to riders in early 2011. If you are interested in testing, please contact Nightrider.com.

 

  Special Notes on the HD NBO2 sensor

You should never solder a O2 sensor wire because the sensor "will breathe" through the cable. The acceptable method of splicing or repairing O2 wiring is with crimp connectors. This information was from Bosch Technical Staff in Europe. Here is the technical description of why you do not solder the connections on the O2 sensor side of the updated wiring.

The outside of the bulb is exposed to the hot gases in the exhaust while the inside of the bulb is vented internally through the sensor body to the outside atmosphere. Older style oxygen sensors actually have a small hole in the body shell so air can enter the sensor, but newer style O2 sensors "breathe" through their wire connectors insulation and have no vent hole.

It's hard to believe, but the tiny amount of space between the insulation/wire and through wire insulation provides enough air to seep into the sensor (for this reason, grease should never be used on O2 sensor leads/connectors because it can block the flow of air). Venting the sensor through the wires rather than with a hole in the body reduces the risk of dirt or water contamination that could foul the sensor from the inside and cause it to eventually fail.

A special thanks to Kristian Heidenfors for all his help and research on the HD Bosch O2 sensor, testing the voltage divider circuit and additional help on SE Race Tuner.

Special Notes on the building these devices

This device is covered by US Patent Law and WIPO Treaty Laws. Any commercial venture to manufacture, sell or distribute this device without appropriate licensing will be subject to legal action. We have no desire to prevent individual riders from building their own DIY circuits. But commercial ventures must obtain appropriate licensing.

Evaluating changes to Software Tuning using dividers

Many riders of Harley-Davidson motorcycles use software tuning programs such as SE Race Tuner, SE Super Tuner, Master Tuner TTS and Techno Research to directly update the Delph ECM. The 2007 and later model motorcycles use closed loop EFI operation. When tuning a bike, riders are often faced with the choice of making a change to the closed loop bias tables or making changes to the VE and AFR tables to alter the fuel ratio of an engine. The ease and simplicity of tuning by maintianing a large closed loop operational area is both prudent from a time management perspective and that this method tends to be emissions friendly. In a tuning environment, it can be an advantage to be able to quickly test CLB table changes without loading the tuning software.

The testing of narrow band O2 sensors can also evaluate changes that will occur as the sensor ages. NBO2 sensor tend to produce higher voltages at the same AFR as they age.

This information is applicable to all motorcycles and automobiles using Narrow Band O2 sensors.


An illegal, unlicensed version of the Nightrider.com ViED* for the Ducati is being sold on another web site. This product is a copy of the Nightrider ViED product. The owner of this web site copied the Nightrider ViED* product and claimed it as his own design. In addition to violating US Patent Law, he violated copyright laws. His unethical and illegal behavior is documented on a Ducati forum after another Rider contacted me about adapting my patent pending product (at the time) for his  Ducati. Shortly afterwards, a ducati o2 manipulator which was an unlicensed version of the Nightrider.com ViED* showed up. Nightrider.com will offer its own, licensed version of the Ducati ViED*/O2 manipulator/fat duc in early 2011 for $60-$70.
Nightrider.com is the originator and Patent Holder for the inline enrichment technology used in the O2 Manipulator. *Protected by U.S Patent 7,805,236.
