EFI Closed Loop Products
Nightrider has developed a variety of products that make alterations to the closed loop fuel mixture of the H-D Delphi ECM ECM. We often get questions about the differences in the products, if the product is compatible with their upgrades or which product is “best” for their particular bike. These tables were created to answer some of those questions.

[1] LC-1 WBO2 is the Nightrider.com supplied Innovate Motorsports LC-1 Wide Band O2 Sensor product with custom cables to adapt it to the H-D wiring harness.
[2] Emissions as tested on 07 FLHX in a certified emissions testing laboratory at Idle. Stock bike versus stock bike with O2 IED. 49-state standards are listed next to tested item. Emissions’ testing shows Hydrocarbons (HC) and Carbon Monoxide (CO). Nitrous Oxide results are not typically tested during state emissions inspections.
[3] Benefits as reported to Nightrider.com, HDForums.com and other online forum groups.
[4] Temperature drops as typically reported by Riders by measuring cylinder heads and exhaust shields. Testing by V-twin oriented magazines reports similar 20 degree results. Temperature drop as measured by thermocouple connected to the exhaust header at the exhaust port are 40-80 degrees. Individual rider results may vary.
[5] MPG change computed based on additional fuel supplied to engine under ideal circumstances. Individual rider results may vary.
[6] As measured on an 07 FLHX by professional riders working for a certified emissions testing laboratory.
[7] Compatibility with 2007>later Harley-Davidson motorcycles has been well established. We can not recommend the use of O2 IED or XiED on 2006 H-D Dyna models. The DYN OiED is specifically for the 2006 Dyna Model bikes.
[8] Tested configurations and results by independent riders can be found at HDForums.com IED thread.

[11] Tested configurations and results by independent riders can be found at HDForums.com IED thread.
[12] Tested configurations and results by independent riders can be found at HDForums.com IED thread.
[13] O2 IED is compatible with SERT, but recommends riders alter Bias Tables to 762 instead.
[14] Advanced Tuning Techniques is possible using custom configured LC-1 programming. Recommend use of Twin Scan II for data logging and data analysis. With SERT, use custom configured Bias Tables. With PCIII, use Nightrider standard LC-1 configuration.
[15] Tuning Guidelines for using the O2 IED with the Power Commander are available.
[16] Technical support at V&H reported that O2 IED and Fuel Pack are compatible according to independent rider contacting company.
[17] Tuning instruction for using the O2 IED with the TFI is available.
[18] V-Rod tested by certified emissions testing laboratory.
[19] The 2009 and later Touring model bikes are approved for use with the FL-XIED, ViED-2, FL-XiED-10, FL-VIED-10, FL-AF XIED-10 and AFXiED.
[20] DYN OiED is specific to 2006 Dyna Models
[21] ViED is a variable ratio IED for all model bikes, allowing AFR’s from 14.5 to 13.6
[22] Buell models using the H-D style 2-wire Narrow Band O2 sensor should be compatible with ViED. The LC-1 WBO2 is compatible with all narrow band O2 sensors. Additional wiring may be required for LC-1 upgrade.
