Buell VIED Testing Update 28-Aug-2009

I have some test results on the Buell VIED on bikes with the DDFI-3. This covers the 2008-2009 X-series Buell's. The testing was performed by a H-D mechanic in a Dealership in Canada. This was a comprehensive test, providing slightly different results than early model bikes with the DDFI-2. Listed below is his e-mail message back to me:

2009 Touring Bike update Aug-27-2009

For a while it looke like late 2009 production Touring models might be able to use the XiED's. I started a new test period to validate this possibility. After additional testing, I found that these late manufacter bikes were not able to use the Inline Enrichment Devices with any more consistency of results than the earlier 2009 Touring bikes. But during this same time, a lot of new information has been discovered. For 2009 Touring bike Riders, what was discovered is a combination of good and bad news.
 

Possible 09 H-D Touring Bike Wiring Harness Issues

Some Technical people I trust reported a potential wiring and ECM connector problem on the late model Harley-Davidson Touring bikes through other channels. This issues is something that others have probably found on some of TC96/103/110 Touring bikes. These wiring problems can cause Check Engine lights to occur and possible engine running issues.

While any unconfirmed report like this should be treated cautiously by any rider, there is strong circumstantial evidence to support this information. There were reports within 72 hours of additional 12-14 2009 and possbily two 2010 Touring bikes exhibiting the symptoms described in this article.

2010 XIED Availability

The 2010 Dyna, Softail and Sportsters use the current XiED's. These bikes use the same XiED, X14iED, ViED and AFXiED's as the 2007,2008,2009 motorcycles. The various Inline Enrichment Devices provide closed loop fuel mixture richening for the 2010 Harley-Davidsion's to bring the AFR from the OEM 14.6:1 to as rich as 13.7:1, depending upon the product.

XIED on 2009 Touring Bikes Update

There are multiple reports of XIED's being used on late manufacture date 2009 Touring Bikes without any of the issues encountered when the bikes first came out. Here is what we have learned.

Simple Field Test to verify proper XIED operation

I have been asked for a simple way to test the various XIED's so riders can verify they are working correctly.

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. 

Throttle Position Versus MAP

Converting a Throttle Position (TPS) to MAP readings can be confusing.

Carburetor Troubleshooting Guide

This guide covers problems and solutions routinely encountered on stock and mildly modified motorcycle engines. As the horsepower goes up, so does the number of potential situations that impact performance or create problems. When the carburetor is acting up on a performance engine, these basic problems must be eliminated as a source of the problem before going on to performance tuning the carburetor.

Harley Closed Loop Fuel Mixture

The OEM Harley-Davidson closed loop fuel mixture is 14.6:1. On Twin Cam 96 engines, the closed loop range generally covers under 4000 RPMs and under 40% throttle. This is going to be 95+% of the time an average rider spends on his bike. Even the most aggressive rider would find it hard to spend more than 5% of this time in open loop.

Narrow Band O2 Sensor

How the narrow band O2 sensor reacts to the fuel mixture has always been something of a mystery to most riders. It can be a little hard to visualize what is going on when some simply tells you that the output changes based on the fuel mixture changing, which is really the amount of oxygen in the exhaust changing. So we thought we would make all of this a little more "visual" and show some very accurate graphs showing what is really happening  at the O2 sensors.

O2 Sensor Failures On Harley-Davidson Bikes

Nightrider occasionally receives some inside information on what is happening inside Harley-Davidson. We cannot divulge our source of information, so there is no way it can be be verified. But we have always found our 'source' to be quite reliable. The latest information has to do with the number of O2 sensors failures being reported by MOCO.

Recession Tuning and Upgrades

Looking for an inexpensive way to add a cam to your TC96? There are ways to upgrade your bike without breaking the bank if you are innovating and are willing to break with convention. There are some very nice bolt-in cams for the TC-96 engines available that offer the same or better power potential than the HD 103 upgrade does. Because installing cams does not 'break the seal' on the top end of the engine, overall reliability should be maintained and you do not have to worry about some torque sensitive components on the engine (heads/cylinders).
