If you search some of the threads there are some great articles out there that explain with the newer "closed" loop systems it is totally unnecessary to add additional controllers. Obviously the manufactures of these controllers won't tell you that as they want to sell product. The controllers do work in those situations where the conditions diticate that the onboard computer goes to full "default" i.e. wide open throttle. Again do some research on just this forum and save yourself some money. Remember that the opinions expressed from forum members are just that - opinions. Old adages and the old ways of doing things die hard. In most instances these opinions don't reflect the newer technologies. Just my humble opinion.

 

I run XiED's and a FuelPak on both our bikes, and I'm very pleased with the results.

 

Your bike is running too lean. The powdery white plugs are an indication of this. Not a good condition if you're worried about engine health over the long haul.

 

I am worried about engine health over the long haul. And while this lean condition may make my motor still last a million miles, I think slightly richer conditions may make it last 2.
This morning I ordered a set of vieds, which is nightriders adjustable resistor for the o2 sensors. Figure Ill start at the leanest setting ( 14.2-1 ) and go from there.
Surely there is huge debate out there over these things but I think this is a really good product to try out. On jap cruisers I have had a bad experience with the pc3, and a decent experience with the fi2000r. All I really want is to have a little more fuel in the mix.
If I pulled a plug out of my pickup, car, or lawn mower and it looked like this I would be worried, why not my Harley? I know they are designed to be lean, but i'm giving this a shot. Not out much if I'm wrong and I'll post results ;}

 

I think this looks cool, and from what I have read, it is a great alternative to some more pricey devices .

Yes, if I wanted something simple such as the XIED. I would seriously look at the Doebek TFI unit.

 

The dobeck and the electronic jet kit are the same idea as the cobra fi2000r. They simply add fuel differently at different rpm zones, just like main, needle, and idle jets. The vied is the same end result, richer fuel on the stock ecu map. It just goes about doing it a little differently, and a couple hundred bucks cheaper.

 

The xIED's only work in closed loop. They will do nothing under heavy loads and WOT. The computer will simply revert to what is programed from the factory which will be too lean. You have spent thousands getting your bike and accessorizing it. Why cheap out now. Do it the right way. In the long run by the time you add up the time and money you spend on half *** fixes you may as well have done it tight the first time.

 

"The xIED's only work in closed loop. They will do nothing under heavy loads and WOT. The computer will simply revert to what is programed from the factory which will be too lean."

Couldn't have been said better. The operating conditions that most require a richer mixture (open loop) are ignored by the xIED's

 

Besides right after start up while its cold, and wot, when is it not in closed loop? It runs rich (by the smell) when started cold, and I am rarely at wot.
