FL-VIED on a 2016 FLTRU
In 2011 I had a 2010 FLHTP. I put on the performance headers from V&H (basically a gutted Cat) and stock pipes .
I spent 100's of miles and many communications back and forth with Steve at NightRider.com
After all the minute changes and trials I found out a curious phenomenon... More is not always better.
These FL-VIED's are "Variable" inline regulators the XIED is fixed (at about 55%)
They adjust the Air Fuel Ratio through the O2 sensor feedback to the ECM.
On the 2010 bike I settled on about 15-20%. Which was very hard to select as the dials were so small. I understand that now, the dials are slightly bigger.
The FL-VIED worked very well for my style of conservative riding. The 2010 was not a great year for the ECM factory tuning and minor changes (like Stage One etc) would definitely require some tuning.
Fast forward to the present...
I have a 2016 FLTRU with CVO pipes and a gutted Header. When the bike had the stock header and the CVO pipes it ran very well. But lacked any punch. It was very quiet and only had power over the 3,000 rpm range.
Once I gutted the header... the power band increased but the idle was just (ever so slightly) off smooth. The sound was deeper and louder and the throttle response was a little better. The pickup was a little better but again, until you got up over 3,000 rpm the power band was limited.
I know many have said you do not need any kind of tuning if you just de-cat the header. And they are correct... You don't have to. Mine ran fine... it was nice, quiet and ran great.... BUT.... a little sluggish or slow (if you know what I mean).
So I just ordered the FL-VIED... I should get it next week.
Here's the facts (from nightrider.com)
No. Zero setting is about 1.5-2% more fuel.
25% = 4%, 50=6, 75=8
So at the Zero setting It still pumps more fuel thru the system than stock. and because I have the CVO pipes on I have got more back-pressure than stock... but I gutted the cat so it evened it out a bit... so I am thinking that I need just a very slight adjustment to smooth things out. So I will start at the Zero setting and go up from there if needed.
If I had the cash I would probably go with the Thundermax system that replaces the ECM... but that gets a little technical and other things like the Fp3 or PC5 etc... double or triple the price. Even Jamie at Fuel Moto ... who can simply flash your existing ECM for the mods you have , costs twice as much.
So... for the money and the simplicity of it all... Let the experiment begin.......
