I have purchased v&h slip ons, a heavy breather and a decatted head pipe for my 2013 SG. The slip ons are already installed with the HD flash. I can't get another $500-$800 from the warden for tuner/tune. I can afford the vieds however, and I just want to know if they will work until I can afford a tuner and dyno run. I really just want more sound as long as it runs as good as it has stock.

 

I have heard good things about them. Not as good as a tuner, but they should richen things up enough to make the bike run better. Don't know what they cost, but you might consider that a Commander V from FuelMoto with a canned load is only 300.00. The load that came with mine might not be perfect, but it is sure close enough for the upgrades I have. Slipons, air cleaner and gutted cat.

yes, fl-vied-10 work. $120.00, easy install.

 

They do what they say they do...they may NOT do what you want them to do.

You need to read the fine print VERY CAREFULLY!

Not trying to bust your chops, but what are you trying to accomplish? Why did you have the HD flash done?

 

I have xl-vied's (non-adjustable) on mine and they do what they promise to do. I did the stage I flash after installing the H-D ventilator and pipes. All told - minus a tuner - the bike runs great and I kept some of my money in my pocket. Others will tell you that you need a tune, and so forth. It all depends on what you want to get. The xl-vied's do not get you every last bit of horsepower and some of the other bennies of a tuner. I was/am fine with that. I ride to enjoy myself, so I'm happy. Your money, your decision.

 

I had them and thought they were working for me, but I think it was just in my head. Decided to just buy the Powervision and am happy with that. If you want to try the Vied's, there are usually some on sale in our classifieds. Sold mine for $70, new they're about $120. Good luck.

 

The HD stage 1 download is around $220 with the dealers labor to down load it for you. Add $120 for the VIED's and you have spent about what a PV or FP3 cost. I read on the Nightridder website that you will loose about 6% in MPG with there products.

 

I didn't notice much difference but I got mine really cheap so it's not a big deal

 

Do they work ?

How do they work ?

I have posted in the past a description of what and how they work with the ECM to adjust the mixture.
Fueled by coffee, but it is pasted below if you want to waste 5 minutes.


You have already paid for an HD flash- it should do whet you want- ?
They sold it to you what did they tell you when you bought it.

I'd suggest that an owner go with 1 system that works, not combining devices which over complicate and may give unexpected results.




I'm at about 15,000 miles on my XIEDS.

still smilin'

XIEDS work for me.

I'll explain what they do.

This applies to the 2007~2009 model bikes ( 2010~2013 use a different but similar sensor incorporating a 12 volt heater circuit)

o2 sensors produce voltage once they warm up to about 600ºF, the voltage is produced by the bi metallic compound(s) reacting to the oxygen content in the exhaust.


a "correct" fuel mixture will produce about .45 volts DC.
More voltage will be produced by a "rich" mixture, less voltage by a "lean" mixture.

the ECM looks for the .45 Volts- if it sees more, it leans out the mixture until the voltage is correct. If it sees less, then it adds fuel until it sees .45 Volts.

The Xied/ Vieds are a simple resistor which trims off a little voltage- so the ECM "thinks" the mixture is slightly lean...so it corrects by making the mixture slightly richer than it would otherwise be.
About 8% richer.

this covers MOST riding conditions- cruising, part throttle.

When the throttle is whacked wide open, the ECM will for a short while refer to preprogrammed maps. when the motor is cold, same thing, the ECM will refer to maps as the o2 sensors have not warmed up and are not providing any voltage.


In my case, the XIEDs are all I need.

I do not plan on future cams, headwork or other performance work- if I were I would likely look at the Thundermax- a more complete solution, it is a replacement ECM.

I am running the XIEDS on my 2009 FLHTC. Ness Big Sucker Intake, Supertrapp Supermegs and no cat header ( stock).
My typical MPG has dropped all the way to 43 MPG from 44 MPG, measured over thousands of miles

the xieds really are just a handful of inexpensive parts, as mentioned in a previous post. The cost of the connectors is probably the highest part of the cost- the retail for everything is probably about $25 for anyone who want to make their own and have figured out the electronic values of the components.
i think they are a fair value- before Xieds, nightrider.com ( Steve Mullen) was a source for great unbiased info on the web for us hobby wrenches.




Some tuner products do not make use of the o2 sensors- in which case the "brain" is always running from maps- there is no feedback loop from the output of the motor (exhaust) to determine if the motor may be running extra rich or extra lean- neither of which are good for performance or longevity.

H-D was 20 years behind the automotive world in finally adding o2 sensors to the EFI system on touring bikes in 2007 ( Buell was much earlier)- a real failing in my opinion.

the o2 sensor provides a very valuable data point to the ECM, surpassed only by the crank sensor.

once in a while in Harley-land, you do not have to spend $500 to get a good result- and if all those savings are added up, eventually you have the funds for a second or third bike- or a 2 or 3 week trip on one of them

They work as advertised. I did the same thing you are doing...Using them long enough to raise funds to do it right with a real tuner. There is no comparision between XEID's and a good reflash tuner that has been set up properly.
