Anyone have experience with the XIED enrichment add-on? Or would I be better investing in a flash/auto tuner to keep the mixture a little richer than stock lean? I plan to keep the intake and exhaust stock. Any other suggestions?

 

just put them on the other day as I don't really have much done. It runs notable better. Also runs cooler. I will put a tuner on at a later date. But for now they work well

 

for many of us with Stage 1 motors, the Nightrider.com xied/vieds work great.

if you plan on motorwork or cams in the future a more complex device will be required.

I have many, many thousands of miles on my bike ( 09 FLHTC) with xieds.

From stock trim to hi flow exhaust and hi flow intake with no cat headers.

Under most riding conditions ( part throttle, cruising) the xieds will make the mixture about 8% richer than it would be otherwise.
My MPG was affected by about 2% ( 44 mpg stock, 43 mpg stage 1 w/ xieds).

The rev limit was left intact, which is ok for me.

Thanks guys. I'm not really concerned about the mpg. The bike runs hot especially on the open road and the baffles look really light tan. Just guessing these things are setup super lean like most new bikes. I'm going to give the XIED's a try. I used to do all the stuff to my bikes but I'm played out on all that. Just want a smooth good runner and stock is fine. Thanks for the info.

 

Get a set of jasons fans for the rest of the heat.

 

For stage 1 they appear to be quite good...

 

what's the theory behind how they work?

 

I have them on my '13. I added an S&S intake and cored out my factory mufflers. I love how they work. Simple, and easy to adjust.
Seazund, they just trick the computer into adding more fuel.

 

the ECM expects to see .45 volts DC from the o2 sensor- that signifies a correct mixture in the cylinder- in real time.

less voltage means the mixture is lean/ more voltage means rich.

so the ecm 'wants' to see .45 volts and will alter the fuel mixture to keep that number constant.

xieds are a simple resistor pack which knocks the .45 VDC down to a lesser value...the ECM responds by making the mixture a little richer to maintain a .45 VDC sensor input.

easy.

What Steve Mullen at Nightrider.com did was figure the values, then build a sturdy, close tolerance unit for us- probably the most expensive parts are the connectors

They have both adjustable and non-adjustable; I don't plan on changing the intake or removing the cat, so the fixed value ones for a stock bike work well for me. I believe I saw some in the classifieds for 50 bucks...
