O2 IED plug-n-play
Our unique "Patent Pending" O2 sensor Inline Enrichment Device (O2 IED) for 2007 and later Harley-Davidson motorcycles with OEM narrow band O2 sensors richens the fuel mixture from 14.7:1 to 14.2:1. By slightly richening the mixture, engine and exhaust temperatures are lowered. The O2 IED will work on Twin Cam, Sportster and V-Rod engines.
This simple, plug-n-play upgrade is inexpensive and can be installed in under 15 minutes. It is the quickest, easist way to reduce engine heat.

LC-1 WBO2 Upgrade
Accurately altering and controlling the closed loop fuel mixture is something that few shops and riders understand. The stock narrow band O2 sensor installed on the 2007 and later Harley-Davidson motorcycles have a very limited range of control over the AFR. Narrow band O2 sensors are only accurate in the 14.0-15.0 range. Wide Band O2 (WBO2) sensors are accurate between 10.0-20.0 AFR ranges.
Air fuel ratios to maximize performance and keep exhaust temperatures as low as practical are in the 13.0-14.0:1. These ratios are considerably richer than the OEM H-D sensors can handle, but are well within the limits of our LC-1 WBO2 upgrade foryour late model H-D motorcycles.
The LC-1 is a programmable Wide Band O2 controller that allows you to set the closed-loop AFR to the ratio of your choice. For most riders, this is in the 13.2-13.5 range, but other AFR's can be choosen.
The LC-1 is also part of a modular tuning system that can provide a level of accuracy in tuning your motorcycle that is similar to that achieved on a Dyno. The LC--1 includes software that allows you to monitor and analyze your existing fuel maps. With the addition of a Scan Tool, you can accurately update your fuel maps using SERT or PowerCommander.
