Hey all, I have these installed on my 12 street bob with big sucker and road rage 2-1. I can't seem to get these to work to my advantage.. I really don't notice an increase in throttle response, etc. I have tried to adjust them all diff ways. Any ideas what I might be doing wrong? Where is the sweet spot? Lol. Maybe I should just get a tune and be done.. Any thoughts? Cheers-

 

Hi,
Only thing I noticed was bike smoother at low speeds, only got slip on's but gonna add big sucker or heavy breather and see if any change

Thanks

I tried them. Didnt have very good luck. Went to a PCV+AT and have never looked back.

 

My autotuner made it happen for my bike.

 

I had them on my SG, got a tune and the bike runs great. I would highly recommend the tune over the XIED's!

 

all the Xieds do is trick you bike into thinking its very lean so it adds more fuel... thats it... get a tuner

 

Xieds are for slipons and air filter upgrade.
Mod further,get tuner.

 

Your upgrades have possible altered set-up beyond the XiED range...it's a band-aid solution vs. total tune. Like other state...(1) get bike tuned (ECM), or (2) get wide-band tuner w/O2 connections so you can adjust for upgrades (current + future).

 

They only work in part throttle conditions when your system in in closed loop. For the most part I believe you will be wasting your money. A PC III can do so much more if you need a tune and for not much money.

 

XiED's are not adjustable, and are not made for your bike. Maybe you have the FL-ViED-10? That is the only adjustable one made for your bike.

Make sure they are grounded per the instructions.

There are thousands that are using these and experience improvement (not as much as a good tune, but still far better than stock). If you have not noticed any improvement, re-check installation-connections, adjust per instructions, if that still yields no improvement you may have a defective pair.

btw, they do have a richening effect on open loop also via the LTFT. Many posts about how that works.





The above say for years 10-11, but are the same for thru 13.

Oh, and check for any exhaust leaks, even the smallest leak will compromise effectiveness.
