Variable Inline
Enrichment Device (ViED)
Installation
Patent Pending
Fits 2007 and 2008 Harley-Davidson®
All Twin Cam,
Sportster and V-Rod modes with OEM O2 sensors (including 2006 Dyna)
Made in the USA
A
‘plug-n-play’ upgrade designed to let the engine equipped with OEM oxygen
sensors run at a richer air fuel ratio in closed loop mode ranging from 14.3:1
to 13.7:1. The improved air fuel mixture has generally shown one of more of the
following positive results:
|
·
lower engine temperature
·
decreased exhaust heat
|
·
improved throttle response
·
less engine ‘ping’
|
Installation Instructions
·
Locate Front/Rear O2 sensors
·
Follow wiring 6-8” to black
connector
o
Front Connector may be located
behind a plastic panel
o
Remove the seat for rear sensor on
Dyna
o
Cut any tie wraps holding the
connectors in place
·
Unplug weather-tight connector
·
Plug the IED between O2 sensor and wiring harness
·
Make sure the connectors lock into
each other
·
Tie wrap the IED in place to
prevent it from hitting the exhaust system
Adjustment Instructions
·
Use a Jeweler’s screwdriver to
make adjustments to the Vied
·
Do not force the ViED dial
adjustment
·
Do not make adjustments while the
engine is running. This might cause a temporary Check Engine light
·
Set the initial value based on the
table of known working AFRs
·
If you get transient Check Engine
light, set the AFR approximately .05 to .1 AFR leaner

Notes:
Richer
closed loop AFR values can not be achieved it any exhaust leaks exist. Even the
smaller exhaust leak can cause check engine lights to occur. It is common for
leaks to occur after slip on muffler or exhaust system upgrades have been done
on the bike.
Do
not expose the ViED to high pressure water stream. Keep ViED out of direct water
spray. Wire loom can be used to help protect the dial from water spray.
